Kelin-Hong/ScrollablePanel

A flexible view for providing a limited rect window into a large data set,just like a two-dimensional RecyclerView. It different from RecyclerView is that it's two-dimensional(just like a Panel) and it pin the itemView of first row and first column in their original location.

# ScrollablePanel --- A flexible view for providing a limited rect window into a large data set,just like a two-dimensional RecyclerView. It different from RecyclerView is that it's two-dimensional(just like a Panel) and it pin the itemView of first row and first column in their original location.  ## Demo ## Apk Download:[ScrollablePanelDemo.apk](art/ScrollablePanelDemo.apk) ## Download ## ```groovy compile 'com.kelin.scrollablepanel:library:1.2.0' ``` ## Usage ## ScrollablePanel is very similar to the RecyclerView and we can use them in the same way. ####1、Initialize ScrollablePanel ```xml <com.kelin.scrollablepanel.library.ScrollablePanel android:id="@+id/scrollable_panel" android:layout_width="match_parent" android:layout_height="match_parent" /> ``` ####2、Adapter This adapter must extend a class called PanelAdapter,We now have to override following methods so that we can implement our logic. ```java public class TestPanelAdapter extends PanelAdapter { private List<List<String>> data; @Override public int getRowCount() { return data.size(); } @Override public int getColumnCount() { return data.get(0).size(); } @Override public int getItemViewType(int row, int column) { return super.getItemViewType(row, column); } @Override public void onBindViewHolder(RecyclerView.ViewHolder holder, int row, int column) { String title = data.get(row).get(column); TitleViewHolder titleViewHolder = (TitleViewHolder) holder; titleViewHolder.titleTextView.setText(title); } @Override public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { return new TestPanelAdapter.TitleViewHolder(LayoutInflater.from(parent.getContext()) .inflate(R.layout.listitem_title, parent, false)); } private static class TitleViewHolder extends RecyclerView.ViewHolder { public TextView titleTextView; public TitleViewHolder(View view) { super(view); this.titleTextView = (TextView) view.findViewById(R.id.title); } } } ``` ####3、Set Adapter ```java @Override protected void onCreate(Bundle savedInstanceState) { ... ... TestPanelAdapter testPanelAdapter = new TestPanelAdapter(); ScrollablePanel scrollablePanel = (ScrollablePanel) findViewById(R.id.scrollable_panel); scrollablePanel.setPanelAdapter(testPanelAdapter); ... ... } ``` ## ChangeLog ## - V1.0.1 (2016-12-01) fix header scroll bug - V1.1.0 (2016-12-21) fix desynchronisation between RV’s & fix dislocation of first column in every row! - V1.2.0 (2016-12-26) Add notifyDataSetChanged & Fix auto reset to original position when first time scroll down! ## License ``` Copyright 2016 Kelin Hong Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.

SimonVT/schematic

Automatically generate ContentProviders

Schematic ========= Automatically generate a ContentProvider backed by an SQLite database. Usage ===== First create a class that contains the columns of a database table. ```java public interface ListColumns { @DataType(INTEGER) @PrimaryKey @AutoIncrement String _ID = "_id"; @DataType(TEXT) @NotNull String TITLE = "title"; } ``` Then create a database that uses this column ```java @Database(version = NotesDatabase.VERSION) public final class NotesDatabase { public static final int VERSION = 1; @Table(ListColumns.class) public static final String LISTS = "lists"; } ``` And finally define a ContentProvider ```java @ContentProvider(authority = NotesProvider.AUTHORITY, database = NotesDatabase.class) public final class NotesProvider { public static final String AUTHORITY = "net.simonvt.schematic.sample.NotesProvider"; @TableEndpoint(table = NotesDatabase.LISTS) public static class Lists { @ContentUri( path = "lists", type = "vnd.android.cursor.dir/list", defaultSort = ListColumns.TITLE + " ASC") public static final Uri LISTS = Uri.parse("content://" + AUTHORITY + "/lists"); } ``` Table column annotations ------------------------ ```java @AutoIncrement @DataType @DefaultValue @NotNull @PrimaryKey @References @Unique ``` Defining an Uri --------------- The ```@ContentUri``` annotation is used when the ```Uri``` does not change. ```java @ContentUri( path = "lists", type = "vnd.android.cursor.dir/list", defaultSort = ListColumns.TITLE + " ASC") public static final Uri LISTS = Uri.parse("content://" + AUTHORITY + "/lists"); ``` If the ```Uri``` is created based on some value, e.g. an id, ```@InexactContentUri``` is used. ```java @InexactContentUri( path = Path.LISTS + "/#", name = "LIST_ID", type = "vnd.android.cursor.item/list", whereColumn = ListColumns._ID, pathSegment = 1) public static Uri withId(long id) { return Uri.parse("content://" + AUTHORITY + "/lists/" + id); } ``` Including in your project ========================= ```groovy dependencies { annotationProcessor 'net.simonvt.schematic:schematic-compiler:{latest-version}' compile 'net.simonvt.schematic:schematic:{latest-version}' } ``` License ======= Copyright 2014 Simon Vig Therkildsen Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.

一个用于app指向性功能高亮的库

# Highlight [  ](https://bintray.com/isanwenyu/maven/Highlight/_latestVersion) 一个用于app指向性功能高亮的库。 有任何意见，欢迎提issue。新建dev分支，欢迎pull request。 ## 效果图 竖屏： <img src="gif/high_light_demo.gif" width="320px"/> 横屏： <img src="gif/highlight3.png" width="320px"/> ## 引入 下载代码，然后： ```xml dependencies { compile project(':highlight') } ``` 或者 ``` compile 'com.isanwenyu.highlight:highlight:1.8.0' ``` 再或者 ``` <dependency> <groupId>com.isanwenyu.highlight</groupId> <artifactId>highlight</artifactId> <version>1.8.0</version> <type>pom</type> </dependency> ``` ## 用法 > 最新用法详情：[https://isanwenyu.github.io/2016/11/23/HighLight-latest-usage/ ](https://isanwenyu.github.io/2016/11/23/HighLight-latest-usage/) ### Next Mode 下一步模式 > Enable next mode and invoke show() method then invoke next() method in HighLight to display tip view in order till remove itself > 调用`enableNext()`开启next模式并显示，然后调用next()方法显示下一个提示布局 直到删除自己 #### 1. 开启next模式并显示 ``` /** * 显示 next模式 我知道了提示高亮布局 * @param view id为R.id.iv_known的控件 * @author isanwenyu@163.com */ public void showNextKnownTipView(View view) { mHightLight = new HighLight(MainActivity.this)// .autoRemove(false)//设置背景点击高亮布局自动移除为false 默认为true // .intercept(false)//设置拦截属性为false 高亮布局不影响后面布局的滑动效果 .intercept(true)//拦截属性默认为true 使下方ClickCallback生效 .enableNext()//开启next模式并通过show方法显示 然后通过调用next()方法切换到下一个提示布局，直到移除自身 // .setClickCallback(new HighLight.OnClickCallback() { // @Override // public void onClick() { // Toast.makeText(MainActivity.this, "clicked and remove HightLight view by yourself", Toast.LENGTH_SHORT).show(); // remove(null); // } // }) .anchor(findViewById(R.id.id_container))//如果是Activity上增加引导层，不需要设置anchor .addHighLight(R.id.btn_rightLight,R.layout.info_known,new OnLeftPosCallback(45),new RectLightShape(0,0,15,0,0))//矩形去除圆角 .addHighLight(R.id.btn_light,R.layout.info_known,new OnRightPosCallback(5),new BaseLightShape(TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,5,getResources().getDisplayMetrics()), TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,5,getResources().getDisplayMetrics()),0) { @Override protected void resetRectF4Shape(RectF viewPosInfoRectF, float dx, float dy) { //缩小高亮控件范围 viewPosInfoRectF.inset(dx,dy); } @Override protected void drawShape(Bitmap bitmap, HighLight.ViewPosInfo viewPosInfo) { //custom your hight light shape 自定义高亮形状 Canvas canvas = new Canvas(bitmap); Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG); paint.setDither(true); paint.setAntiAlias(true); //blurRadius必须大于0 if(blurRadius>0){ paint.setMaskFilter(new BlurMaskFilter(blurRadius, BlurMaskFilter.Blur.SOLID)); } RectF rectF = viewPosInfo.rectF; canvas.drawOval(rectF, paint); } }) .addHighLight(R.id.btn_bottomLight,R.layout.info_known,new OnTopPosCallback(),new CircleLightShape()) .addHighLight(view,R.layout.info_known,new OnBottomPosCallback(10),new OvalLightShape(5,5,20)) .setOnRemoveCallback(new HighLightInterface.OnRemoveCallback() {//监听移除回调 @Override public void onRemove() { Toast.makeText(MainActivity.this, "The HightLight view has been removed", Toast.LENGTH_SHORT).show(); } }) .setOnShowCallback(new HighLightInterface.OnShowCallback() {//监听显示回调 @Override public void onShow(HightLightView hightLightView) { Toast.makeText(MainActivity.this, "The HightLight view has been shown", Toast.LENGTH_SHORT).show(); } }).setOnNextCallback(new HighLightInterface.OnNextCallback() { @Override public void onNext(HightLightView hightLightView, View targetView, View tipView) { // targetView 目标按钮 tipView添加的提示布局 可以直接找到'我知道了'按钮添加监听事件等处理 Toast.makeText(MainActivity.this, "The HightLight show next TipView，targetViewID:"+(targetView==null?null:targetView.getId())+",tipViewID:"+(tipView==null?null:tipView.getId()), Toast.LENGTH_SHORT).show(); } }); mHightLight.show(); } ``` #### 2. 调用next()方法依次显示之前添加到提示布局 最后自动移除 ``` /** * 响应所有R.id.iv_known的控件的点击事件 * <p> * 移除高亮布局 * </p> * * @param view */ public void clickKnown(View view) { if(mHightLight.isShowing() && mHightLight.isNext())//如果开启next模式 { mHightLight.next(); }else { remove(null); } } ``` #### 3. 下一步回调监听 ``` /** * 下一个回调监听 只有Next模式下生效 */ public static interface OnNextCallback { /** * 监听下一步动作 * * @param hightLightView 高亮布局控件 * @param targetView 高亮目标控件 * @param tipView 高亮提示控件 */ void onNext(HightLightView hightLightView, View targetView, View tipView); } ``` #### 4. mAnchor根布局完成回调监听(页面加载完成，自动显示) > 针对下方问题4的优化方案 在Activity或Fragment onCreated方法中构造HighLight > 通过mAnchor.getViewTreeObserver().addOnGlobalLayoutListener(this)实现 ``` /** * 当界面布局完成显示next模式提示布局 * 显示方法必须在onLayouted中调用 * 适用于Activity及Fragment中使用 * 可以直接在onCreated方法中调用 * @author isanwenyu@163.com */ public void showNextTipViewOnCreated(){ mHightLight = new HighLight(MainActivity.this)// .anchor(findViewById(R.id.id_container))//如果是Activity上增加引导层，不需要设置anchor .autoRemove(false) .enableNext() .setOnLayoutCallback(new HighLightInterface.OnLayoutCallback() { @Override public void onLayouted() { //mAnchor界面布局完成添加tipview mHightLight.addHighLight(R.id.btn_rightLight,R.layout.info_gravity_left_down,new OnLeftPosCallback(45),new RectLightShape()) .addHighLight(R.id.btn_light,R.layout.info_gravity_left_down,new OnRightPosCallback(5),new CircleLightShape()) .addHighLight(R.id.btn_bottomLight,R.layout.info_gravity_left_down,new OnTopPosCallback(),new CircleLightShape()); //然后显示高亮布局 mHightLight.show(); } }) .setClickCallback(new HighLight.OnClickCallback() { @Override public void onClick() { Toast.makeText(MainActivity.this, "clicked and show next tip view by yourself", Toast.LENGTH_SHORT).show(); mHightLight.next(); } }); } ``` ### Nomarl Mode 普通模式 对于上面效果图中的一个需要高亮的View，需要通过下面的代码 ``` /** * 显示我知道了提示高亮布局 * @param view id为R.id.iv_known的控件 * @author isanwenyu@163.com */ public void showKnownTipView(View view) { mHightLight = new HighLight(MainActivity.this)// .autoRemove(false)//设置背景点击高亮布局自动移除为false 默认为true .intercept(false)//设置拦截属性为false 高亮布局不影响后面布局的滑动效果 而且使下方点击回调失效 .setClickCallback(new HighLight.OnClickCallback() { @Override public void onClick() { Toast.makeText(MainActivity.this, "clicked and remove HightLight view by yourself", Toast.LENGTH_SHORT).show(); remove(null); } }) .anchor(findViewById(R.id.id_container))//如果是Activity上增加引导层，不需要设置anchor .addHighLight(R.id.btn_rightLight,R.layout.info_known,new OnLeftPosCallback(45),new RectLightShape()) .addHighLight(R.id.btn_light,R.layout.info_known,new OnRightPosCallback(5),new CircleLightShape(0,0,0)) .addHighLight(R.id.btn_bottomLight,R.layout.info_known,new OnTopPosCallback(),new CircleLightShape()) .addHighLight(view,R.layout.info_known,new OnBottomPosCallback(10),new OvalLightShape(5,5,20)); mHightLight.show(); // //added by isanwenyu@163.com 设置监听器只有最后一个添加到HightLightView的knownView响应了事件 // //优化在布局中声明onClick方法 {@link #clickKnown(view)}响应所有R.id.iv_known的控件的点击事件 // View decorLayout = mHightLight.getHightLightView(); // ImageView knownView = (ImageView) decorLayout.findViewById(R.id.iv_known); // knownView.setOnClickListener(new View.OnClickListener() // { // @Override // public void onClick(View view) { // remove(null); // } // }); } ``` anchor()指你需要在哪个view上加一层透明的蒙版，如果不设置，默认为android.R.id.content。也就是说，该库支持局部范围内去高亮某些View. addHighLight包含3个参数： * 参数1：需要高亮view的id，这个没什么说的 * 参数2：你的tip布局的layoutId，也就是箭头和文字，你自己编写个布局，参考demo即可。 * 参数3：是个接口，接口包含一系列的位置信息，如下 ```xml /** * @param rightMargin 高亮view在anchor中的右边距 * @param bottomMargin 高亮view在anchor中的下边距 * @param rectF 高亮view的l,t,r,b,w,h都有 * @param marginInfo 设置你的布局的位置，一般设置l,t或者r,b */ ``` 哈，提供了一堆的位置信息，但是你要做的，只是去设置leftMargin和topMargin；或者rightMargin和bottomMargin。 目前看起来，我觉得位置信息够了，当然如果你有想法欢迎提出。 哈，是不是参数比较多，看着烦，如果你图省事，可以提供一个枚举，提供4个或者8个默认的位置，这个事呢，dota1群`@李志云`已经完成~认识的话可以去找他。 * 参数4：高亮形状 抽象类BaseLightShape(dx,dy,blurRadius) ```xml /** * @param dx 水平方向偏移 * @param dy 垂直方向偏移 * @param blurRadius 模糊半径 默认15px 0不模糊 */ ``` 两个抽象方法： ``` /** * reset RectF for Shape by dx and dy. 根据dx，dy重置viewPosInfoRectF大小 * @param viewPosInfoRectF * @param dx * @param dy */ protected abstract void resetRectF4Shape(RectF viewPosInfoRectF, float dx, float dy); /** * draw shape into bitmap. 绘制高亮形状到传递过来的图片画布上 * @param bitmap * @param viewPosInfo * @see zhy.com.highlight.view.HightLightView#addViewForEveryTip(HighLight.ViewPosInfo) * @see HightLightView#buildMask() */ protected abstract void drawShape(Bitmap bitmap, HighLight.ViewPosInfo viewPosInfo); ``` BaseLightShape的实现类：RectLightShape（矩形）、CircleLightShape（圆形）、OvalLightShape（椭圆），具体实现请查看代码 ## Question 问题 1. 添加的提示布局怎么在屏幕中水平居中显示（垂直居中类似） > 提示布局根布局`android:layout_width="match_parent"` `android:gravity="center_horizontal"` > 自定义定位参数`rightMargin=0` 2. 怎么针对同一个高亮控件添加多个提示布局 > `addHighLight` 多次添加 第一个参数使用同一个控件id即可 3. 高亮布局显示后 底层布局有变化 怎么更新高亮布局 > `mHighLight.getHightLightView().requestLayout()` 掉用后高亮布局会重新布局及绘制 4. ~~页面加载完成，自动显示，应该放在哪里调用？~~ **v1.8.0及以后版本建议使用`setOnLayoutCallback`方式 老版本使用下面方案** ``` @Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus); //界面初始化后显示高亮布局 mHightLight.show(); } 或者: getWindow().getDecorView().getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() { @Override public void onGlobalLayout() { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) { getWindow().getDecorView().getViewTreeObserver() .removeOnGlobalLayoutListener(this); } //界面初始化后显示高亮布局 initHightLight(); mHightLight.show(); } }); ``` 5. ~~如果使用viewpager非第一页高亮布局 有可能定位到屏幕外~~ **v1.7.2版本已修复 具体方案参考#21** > 感谢 @liyanxi 提供的方案 会更新到 [README.md](https://github.com/isanwenyu/Highlight/blob/master/README.md) ``` //自定义高亮形状 final HighLight.LightShape mLightShape = new BaseLightShape() { @Override protected void resetRectF4Shape(RectF viewPosInfoRectF, float dx, float dy) { //重置viewPosInfoRectF 模掉屏幕宽度 得到真实的left viewPosInfoRectF.offsetTo(viewPosInfoRectF.left % DeviceUtil.getScreenDispaly(getActivity())[0], viewPosInfoRectF.top); } ...... ``` ## Changelog 更改历史 See details in [CHANGELOG.md](CHANGELOG.md) file. ## 致谢 - 感谢android day day dota1群，苏苏，提供的图片资源。 - thx for `李志云@dota1`的测试、修改、提议。 - thx for [@zj593743143](https://github.com/zj593743143)的测试和建议

kaz-Anova/StackNet

StackNet is a computational, scalable and analytical Meta modelling framework

# StackNet This repository contains StackNet Meta modelling methodology (and software) which is part of my work as a PhD Student in the computer science department at [UCL](http://www.cs.ucl.ac.uk/home/). My PhD was sponsored by [dunnhumby](http://www.dunnhumby.com/). StackNet is empowered by [H2O](https://github.com/h2oai/h2o-3)'s [agorithms](http://docs.h2o.ai/h2o/latest-stable/h2o-docs/data-science.html) (**NEW**) There is a [Python implementation of StackNet](https://github.com/h2oai/pystacknet) StackNet and other topics can now be discussed on [FaceBook](https://www.facebook.com/StackNet/) too : ## Contents - [What is StackNet](#what-is-stacknet) - [How does it work](#how-does-it-work) - [The Modes](#the-modes) - [Some Notes about StackNet](#some-notes-about-stacknet) - [Algorithms contained](#algorithms-contained) - [Algorithm's Tuning parameters](#algorithms-tuning-parameters) - [Run StackNet](#run-stacknet) - [Installations](#installations) - [Command Line Parameters](#command-line-parameters) - [Data Format](#data-format) - [Commandline Train Statement](#commandline-train-statement) - [Commandline predict Statement](#commandline-predict-statement) - [Examples](#examples) - [Run StackNet from within Java code](#run-stacknet-from-within-java-code) - [Potential Next Steps](#potential-next-steps) - [Reference](#reference) - [News](#news) - [Special Thanks](#special-thanks)  ## What is StackNet StackNet is a computational, scalable and analytical framework implemented with a software implementation in Java that resembles a feedforward neural network and uses Wolpert's stacked generalization [1] in multiple levels to improve accuracy in machine learning problems. In contrast to feedforward neural networks, rather than being trained through back propagation, the network is built iteratively one layer at a time (using stacked generalization), each of which uses the final target as its target. The Sofware is made available under MIT licence. [1] Wolpert, D. H. (1992). Stacked generalization. *Neural networks*, 5(2), 241-259. ## How does it work Given some input data, a neural network normally applies a perceptron along with a transformation function like relu, sigmoid, tanh or others. The StackNet model assumes that this function can take the form of any supervised machine learning algorithm Logically the outputs of each neuron, can be fed onto next layers. The algorithms can be classifiers or regressors or any estimator that produces an output.. For classification problems, to create an output prediction score for any number of unique categories of the response variable, all selected algorithms in the last layer need to have outputs dimensionality equal to the number those unique classes. In case where there are many such classifiers, the results is the scaled average of all these output predictions and can be written as: ## The Modes The stacking element of the StackNet model could be run with two different modes. ### Normal stacking mode The first mode (e.g. the default) is the one already mentioned and assumes that in each layer uses the predictions (or output scores) of the direct previous one similar with a typical feedforward neural network or equivalently: ### Restacking mode The second mode (also called restacking) assumes that each layer uses previous neurons activations as well as all previous layers neurons (including the input layer). Therefore the previous formula can be re-written as: The intuition behind this mode is derived from the fact that the higher level algorithm has extracted information from the input data, but rescanning the input space may yield new information not obvious from the first passes. This is also driven from the forward training methodology discussed below and assumes that convergence needs to happen within one model iteration. The modes may also be viewed bellow:  ## K-fold Training The typical neural networks are most commonly trained with a form of backpropagation, however, stacked generalization requires a forward training methodology that splits the data into two parts – one of which is used for training and the other for predictions. The reason this split is necessary is to avoid overfitting . However splitting the data into just two parts would mean that in each new layer the second part needs to be further dichotomized increasing the bias as each algorithm will have to be trained and validated on increasingly fewer data. To overcome this drawback, the algorithm utilises a k-fold cross validation (where k is a hyperparameter) so that all the original training data is scored in different k batches thereby outputting n shape training predictions where n is the size of the samples in the training data. Therefore the training process consists of two parts: 1. Split the data k times and run k models to output predictions for each k part and then bring the k parts back together to the original order so that the output predictions can be used in later stages of the model. 2. Rerun the algorithm on the whole training data to be used later on for scoring the external test data. There is no reason to limit the ability of the model to learn using 100% of the training data since the output scoring is already unbiased (given that it is always scored as a holdout set). The K-fold train/predict process is illustrated below:  It should be noted that (1) is only applied during training to create unbiased predictions for the second layers model to fit one. During the scoring time (and after model training is complete) only (2) is in effect. All models must be run sequentially based on the layers, but the order of the models within the layer does not matter. In other words, all models of layer one need to be trained to proceed to layer two but all models within the layer can be run asynchronously and in parallel to save time. The k-fold may also be viewed as a form of regularization where a smaller number of folds (but higher than 1) ensure that the validation data is big enough to demonstrate how well a single model could generalize. On the other hand higher k means that the models come closer to running with 100% of the training and may yield more unexplained information. The best values could be found through cross-validation. Another possible way to implement this could be to save all the k models and use the average of their predicting to score the unobserved test data, but this has all the models never trained with 100% of the training data and may be suboptimal. ## Some Notes about StackNet StackNet is (commonly) **better than the best single model it contains in each first layer** however, its ability to perform well still relies on a mix of strong and diverse single models in order to get the best out of this Meta modelling methodology. StackNet (methodology - not the software) was also used to win the [Truly Native](http://blog.kaggle.com/2015/12/03/dato-winners-interview-1st-place-mad-professors/ ) data modelling competition hosted by the popular data science platform Kaggle in 2015 StackNet in simple terms is also explained in [kaggle's blog](http://blog.kaggle.com/2017/06/15/stacking-made-easy-an-introduction-to-stacknet-by-competitions-grandmaster-marios-michailidis-kazanova/) Network's example:  StackNet is made available now with a handful of classifiers and regressors. The implementations are based on the original papers and software. However, most have some personal tweaks in them. ## Algorithms contained ### Native - [AdaboostForestRegressor](/parameters/PARAMETERS.MD#adaboostforestregressor) - [AdaboostRandomForestClassifier](/parameters/PARAMETERS.MD#adaboostrandomforestclassifier) - [DecisionTreeClassifier](/parameters/PARAMETERS.MD#decisiontreeclassifier) - [DecisionTreeRegressor](/parameters/PARAMETERS.MD#decisiontreeregressor) - [GradientBoostingForestClassifier](/parameters/PARAMETERS.MD#gradientboostingforestclassifier) - [GradientBoostingForestRegressor](/parameters/PARAMETERS.MD#gradientboostingforestregressor) - [RandomForestClassifier](/parameters/PARAMETERS.MD#randomforestclassifier) - [RandomForestRegressor](/parameters/PARAMETERS.MD#randomforestregressor) - [Vanilla2hnnregressor](/parameters/PARAMETERS.MD#vanilla2hnnregressor) - [Vanilla2hnnclassifier](/parameters/PARAMETERS.MD#vanilla2hnnclassifier) - [Softmaxnnclassifier](/parameters/PARAMETERS.MD#softmaxnnclassifier) - [Multinnregressor](/parameters/PARAMETERS.MD#multinnregressor) - [NaiveBayesClassifier](/parameters/PARAMETERS.MD#naivebayesclassifier) - [LSVR](/parameters/PARAMETERS.MD#lsvr) - [LSVC](/parameters/PARAMETERS.MD#lsvc) - [LogisticRegression](/parameters/PARAMETERS.MD#logisticregression) - [LinearRegression](/parameters/PARAMETERS.MD#linearregression) - [LibFmRegressor](/parameters/PARAMETERS.MD#libfmregressor) - [LibFmClassifier](/parameters/PARAMETERS.MD#libfmclassifier) ### Native - Not fully developed - knnClassifier - knnRegressor - KernelmodelClassifier - KernelmodelRegressor ### Wrappers - [XgboostRegressor](/parameters/PARAMETERS.MD#xgboostregressor) - [XgboostClassifier](/parameters/PARAMETERS.MD#xgboostclassifier) - [LightgbmRegressor](/parameters/PARAMETERS.MD#lightgbmregressor) - [LightgbmClassifier](/parameters/PARAMETERS.MD#lightgbmclassifier) - [FRGFRegressor](/parameters/PARAMETERS.MD#frgfegressor) - [FRGFClassifier](/parameters/PARAMETERS.MD#frgfClassifier) - [OriginalLibFMClassifier](/parameters/PARAMETERS.MD#originallibfmclassifier)(**New**) - [OriginalLibFMRegressor](/parameters/PARAMETERS.MD#originallibfmregressor)(**New**) - [VowpaLWabbitClassifier](/parameters/PARAMETERS.MD#vowpalwabbitclassifier)(**New**) - [VowpaLWabbitRegressor](/parameters/PARAMETERS.MD#vowpalwabbitregressor)(**New**) - [libffmClassifier](/parameters/PARAMETERS.MD#libffmclassifier)(**New**) ### H2O - [H2ODeepLearningClassifier](/parameters/PARAMETERS.MD#h2odeeplearningclassifier) - [H2ODeepLearningRegressor](/parameters/PARAMETERS.MD#h2odeeplearningregressor) - [H2ODrfClassifier](/parameters/PARAMETERS.MD#h2odrfclassifier) - [H2ODrfRegressor](/parameters/PARAMETERS.MD#h2odrfregressor) - [H2OGbmClassifier](/parameters/PARAMETERS.MD#h2ogbmclassifier) - [H2OGbmRegressor](/parameters/PARAMETERS.MD#h2ogbmregressor) - [H2OGlmClassifier](/parameters/PARAMETERS.MD#h2oglmclassifier) - [H2OGlmRegressor](/parameters/PARAMETERS.MD#h2oglmregressor) - [H2ONaiveBayesClassifier](/parameters/PARAMETERS.MD#h2onaivebayesclassifier) ### Python #### Sklearn(**New**) - [SklearnAdaBoostClassifier](/parameters/PARAMETERS.MD#sklearnadaboostclassifier) - [SklearnAdaBoostRegressor](/parameters/PARAMETERS.MD#sklearnadaboostregressor) - [SklearnDecisionTreeClassifier](/parameters/PARAMETERS.MD#sklearndecisiontreeclassifier) - [SklearnDecisionTreeRegressor](/parameters/PARAMETERS.MD#sklearndecisiontreeregressor) - [SklearnExtraTreesClassifier](/parameters/PARAMETERS.MD#sklearnextratreesclassifier) - [SklearnExtraTreesRegressor](/parameters/PARAMETERS.MD#sklearnextratreesregressor) - [SklearnknnClassifier](/parameters/PARAMETERS.MD#sklearnknnclassifier) - [SklearnknnRegressor](/parameters/PARAMETERS.MD#sklearnknnregressor) - [SklearnMLPClassifier](/parameters/PARAMETERS.MD#sklearnmlpclassifier) - [SklearnMLPRegressor](/parameters/PARAMETERS.MD#sklearnmlpregressor) - [SklearnRandomForestClassifier](/parameters/PARAMETERS.MD#sklearnrandomforestclassifier) - [SklearnRandomForestRegressor](/parameters/PARAMETERS.MD#sklearnrandomforestregressor) - [SklearnSGDClassifier](/parameters/PARAMETERS.MD#sklearnsgdclassifier) - [SklearnSGDRegressor](/parameters/PARAMETERS.MD#sklearnsgdregressor) - [SklearnsvmClassifier](/parameters/PARAMETERS.MD#sklearnsvmclassifier) - [SklearnsvmRegressor](/parameters/PARAMETERS.MD#sklearnsvmregressor) #### Keras - [KerasnnClassifier](/parameters/PARAMETERS.MD#kerasnnclassifier) - [KerasnnRegressor](/parameters/PARAMETERS.MD#kerasnnregressor) #### Generic for user defined scripts (**New**) - [PythonGenericClassifier](/parameters/PARAMETERS.MD#pythongenericclassifier) - [PythonGenericRegressor](/parameters/PARAMETERS.MD#pythongenericregressor) ## Algorithm's Tuning parameters For the common models, have a look at: [parameters](/parameters/PARAMETERS.MD) ## Run StackNet You can do so directly from the jar file, using Java higher than 1.6. You need to add Java as an environmental variable (e.g., add it to PATH). The basic format is: ``` Java –jar stacknet.jar [train or predict] [task=regression or classification] [parameter = value] ``` ## Installations This sections explains how to install the different external tools StackNet uses in its ensemble. ### Install Xgboost Awesome xgboost can be used as a subprocess now in StackNet. This would require privileges to save and change files where the .jar is executed. It is already pre-compiled for windows(64), mac and linux. **verify that the 'lib' folder os in the same directory where the StackNet.jar file is**. By default it should be there when you do `git clone` for linux and mac you most probably need to change privileges for the executable : ``` cd lib/ cd linux/ cd xg/ chmod +x xgboost ``` You can test that it works with : `./xgboost` It should print : `Usage: <config>` In windows and mac the behaviour should be similar. After executing `xgboost` from inside the `lib/your_operation_system/xg/` you should see the: `Usage: <config>` If you don't see this, then you need to compile it manually and drop the executables inside `lib/your_operation_system/xg/` . You may find the follwing sources usefull: - [mac](https://www.ibm.com/developerworks/community/blogs/jfp/entry/Installing_XGBoost_on_Mac_OSX?lang=en) - [windows1](https://stackoverflow.com/questions/33749735/how-to-install-xgboost-package-in-python-windows-platform) ,[windows2](https://www.ibm.com/developerworks/community/blogs/jfp/entry/Installing_XGBoost_For_Anaconda_on_Windows?lang=en) - [linux](https://gist.github.com/DanielBeckstein/932087ee116cc2f72bfc6e3e078e899d) Small Note: The user would need to delete the '.mod' files from inside the `model/` folder when no longer need them. StackNet does not do that automatically as it is not possible to determine when they are not needed anymore. **IMPORTANT NOTE:** This implementation does not include all Xgboost's features and the user is advised to use it directly from source to exploit its full potential. Also the version included is 6.0 and it is not certain whether it will be updated in the future as it required manual work to find all libraries and files required that need to be included for it to run. The performance and memory consumption will also be worse than running it directly from source. Additionally the descritpion of the parameters may not match the one in the offcial website, hence it is advised to use [xgboost's online parameter thread in github](https://github.com/dmlc/xgboost/blob/master/doc/parameter.md) for more information about them. ### Install lightGBM [lightGBM](https://github.com/Microsoft/LightGBM) can be used as a subprocess now in StackNet. This would require privileges to save and change files where the .jar is executed. It is already pre-compiled for windows(64), mac and linux. **Verify that the 'lib' folder is in the same directory where the StackNet.jar file is**. By default it should be there when you do `git clone` for linux and mac you most probably need to change privileges for the executable : ``` cd lib/ cd linux/ cd lightgbm/ chmod +x lightgbm ``` You can test that it works with : `./lightgbm` It should print something in the form of: ``` [LightGBM] [Info] Finished loading parameters [LightGBM] [Fatal] No training/prediction data, application quit Met Exceptions: No training/prediction data, application quit ``` In windows and mac the behaviour should be similar. After executing `lightgbm` from inside the `lib/your_operation_system/lightgbm/` you should see the: `[LightGBM] [Info] Finished loading parameters...` If you don't see this, then you need to compile it manually and drop the executables inside `lib/your_operation_system/lightgbm/` . You may find the follwing sources usefull: [Install LightGBM](https://github.com/Microsoft/LightGBM/wiki/Installation-Guide) Small Note: The user would need to delete the '.mod' files from inside the `model/` folder when no longer need them. StackNet does not do that automatically as it is not possible to determine when they are not needed anymore. **IMPORTANT NOTE:** This implementation does not include all LightGBM's features and the user is advised to use it directly from source to exploit its full potential. it is not certain whether it will be updated in the future as it required manual work to find all libraries and files required that need to be included for it to run. The performance and memory consumption will also be worse than running it directly from source. Additionally the descritpion of the parameters may not match the one in the offcial website, hence it is advised to use [LightGBM's online parameter thread in github](https://github.com/Microsoft/LightGBM/blob/master/docs/Parameters.md) for more information about them. ### Install H2O Algorithms All the required jars are already packaged within the StackNet jar, however the user may find them inside the repo too. No special installation is required , but experimentally system protection might be blocking it , therefore make certain that the StackNet.jar is in the exceptions (firewall). Additionally the first time StackNet uses an H2o Algorithm within the ensemble it takes more time (in comparison to every other time) because it sets up a cluster . ### Install Fast_rgf [fast_rgf](https://github.com/baidu/fast_rgf) can be used as a subprocess now in StackNet. This would require privileges to save and change files where the .jar is executed. It is already pre-compiled for windows(64), mac and linux. **Verify that the 'lib' folder is in the same directory where the StackNet.jar file is**. By default it should be there when you do `git clone` for linux and mac you most probably need to change privileges for the executable : ``` cd lib/ cd linux/ cd frgf/ chmod +x forest_train chmod +x forest_predict ``` You can test that it works with : `./forest_train` It should print something in the form of: ``` using up to x threads ``` In windows and mac the behaviour should be similar. After executing `forest_train` from inside the `lib/your_operation_system/frgf/` you should see the: `using up to x threads...` If you don't see this, then you need to compile it manually and drop the executables inside `lib/your_operation_system/frgf/` . If you need to make the compilling manually for windows, you may find useful to download cmake fom : [Install cmake](https://cmake.org/download/) and use **mingw32-make.exe** as a compiler. Small Note: The user would need to delete the '.mod' files from inside the `model/` folder when no longer need them. StackNet does not do that automatically as it is not possible to determine when they are not needed anymore. **IMPORTANT NOTE:** This implementation does not include all fast_rgf's features and the user is advised to use it directly from source to exploit its full potential. it is not certain whether it will be updated in the future as it required manual work to find all libraries and files required that need to be included for it to run. The performance and memory consumption will also be worse than running it directly from source. Additionally the descritpion of the parameters may not match the one in the offcial website, hence it is advised to use [fast_rgf's online parameter thread in github](https://github.com/baidu/fast_rgf/tree/master/examples) for more information about them. ### Install Sklearn Algorithms To install [Sklearn](http://scikit-learn.org/stable/) in StackNet you need **python higher-equal-to 2.7**. Python needs to be found in **PATH** as StackNet makes subprocesses in the command line. This would require privileges to save and change files where the .jar is executed. **verify that the 'lib' folder is in the same directory where the StackNet.jar file is** Once Python is installed and can be found on PATH, the user needs to isnstall **sklearn version 0.18.2** . The following should do the trick in linux and mac. ``` pip install scipy pip install sklearn ``` For an easier installation in windows, the user could download [Anaconda](https://www.continuum.io/downloads) and make certain to check the **Add Anaconda's python to PATH** when it shows up during the installation. All sklearn python scripts executed by StackNet are put in `lib/python/` ### Install Python Generic Algorithms This a new feature that allows the user to run his/her own models as long as all libraries required can be found in his/her system when calling python. Assuming python is installed as explained in sklearn version above, the user may have a look inside **lib/python/**. The scripts **PythonGenericRegressor0.py** and **PythonGenericClassifier0.py** are sample scripts that show how to format these models. The '0' is the main hyper parameter (called index) of the model PythonGenericRegressor (or PythonGenericClassifier). The data gets loaded in sparse format, but after this the user could add whetver he/she wants. One could make many scritps and name them PythonGenericRegressor1,PythonGenericRegressor2...PythonGenericRegressorN and call them as: ``` PythonGenericRegressor index:1 seed:1 verbose:False PythonGenericRegressor index:2 seed:1 verbose:False PythonGenericRegressor index:N seed:1 verbose:False ``` Once again **Verify that the 'lib' folder in the same directory where the StackNet.jar file is**. ### Install original libfm [libFM](https://github.com/srendle/libfm) can be used as a subprocess now in StackNet. This would require privileges to save and change files where the .jar is executed. It is already pre-compiled for windows(64), mac and linux. Note for windows libfm is compiled with [cygwin](https://www.cygwin.com/) **Verify that the 'lib' folder is in the same directory where the StackNet.jar file is**. By default it should be there when you do `git clone` for linux and mac you most probably need to change privileges for the executable : ``` cd lib/ cd linux/ cd libfm/ chmod +x libfm ``` You can test that it works with : `./libfm` It should print something in the form of: ``` libFM Version: 1.4.2 ... ... ``` In windows and mac the behaviour should be similar. After executing `libfm` from inside the `lib/your_operation_system/libfm/` you should see the same. If you don't see this, **then you need to compile it manually** and drop the executables inside `lib/your_operation_system/libfm/`. You may find the follwing sources usefull: [libfm manual](http://www.libfm.org/libfm-1.42.manual.pdf) **IMPORTANT NOTE:** This implementation may not include all libFM features plus it actually uses a version of it **that had a bug** on purpose. You can find more information about why this was chosen in the following [python wrapper for libFM](https://github.com/jfloff/pywFM). It basically had this bug that was allowing you to get the parameters of the trained models for all training methods. These parameters are now extracted once a model has been trained and the scoring uses only these parameters (e.g. not the libFM executable). Also, multiclass problems are formed as binary 1-vs-all. Bear in mind the [licence of libfm](https://github.com/srendle/libfm/blob/master/license.txt). If you find it useful, cite the following paper : Rendle, S. (2012). Factorization machines with libfm. *ACM Transactions on Intelligent Systems and Technology (TIST)*, 3(3), 57.Chicago . [Link](http://www.csie.ntu.edu.tw/~b97053/paper/Factorization%20Machines%20with%20libFM.pdf) ### Install vowpal wabbit [vowpal wabbit](https://github.com/JohnLangford/vowpal_wabbit) can be used as a subprocess now in StackNet. This would require privileges to save and change files where the .jar is executed. It is already pre-compiled for windows(64) and linux. **Mac** was more difficult than expected and generally there is a lack of expertise working with Mac. If someone could help here, please email me at kazanovassoftware@gmail.com. For mac, you have to install vowpal wabbit from source and drop the executable in `lib/mac/vw/`. Consider [the following link](https://github.com/JohnLangford/vowpal_wabbit#mac-os-x-specific-info). `brew install vowpal-wabbit` will most probably do the trick. If that does not work, you may execute the`lib/mac/vw/script.sh`. This is not advised though as it will override some files you may have already installed - use it as a last resort. **Verify that the 'lib' folder is in the same directory where the StackNet.jar file is**. By default it should be there when you do `git clone` for linux and mac you most probably need to change privileges for the executable : ``` cd lib/ cd linux/ cd vw/ chmod +x vw ``` You can test that it works with : `./vw` It should print something in the form of: ``` Num weight bits = 18 learning rate = 0.5 initial_t = 0 ... ``` In windows and mac the behaviour should be similar. After executing `vw` from inside the `lib/your_operation_system/vw/` you should see the same. If you don't see this, **then you need to compile it manually** and drop the executables inside `lib/your_operation_system/vw/`. You may find the follwing sources usefull: [Download suggestions](https://github.com/JohnLangford/vowpal_wabbit/wiki/Download) **IMPORTANT NOTE:** This implementation may not include all Vowpal Wabbit features and the user is advised to use it directly from the source. Also the version may not be the final and it is not certain whether it will be updated in the future as it required manual work to find all libraries and files required that need to be included for it to run. The performance and memory consumption will also be worse than running directly. Additionally the descritpion of the parameters may not match the one in the website, hence it is advised to use [VW's online parameter thread in github](https://github.com/JohnLangford/vowpal_wabbit/wiki/Command-line-arguments) for more information about them. ### Install libffm [libffm](https://github.com/guestwalk/libffm) can be used as a subprocess now in StackNet. This would require privileges to save and change files where the .jar is executed. It is already pre-compiled for windows(64), mac and linux. **Verify that the 'lib' folder is in the same directory where the StackNet.jar file is**. By default it should be there when you do `git clone` for linux and mac you most probably need to change privileges for the executable : ``` cd lib/ cd linux/ cd libffm/ chmod +x ffm-train chmod +x ffm-predict ``` You can test that it works with : `./ffm-train` It should print something in the form of: ``` usage: ffm-train [options] training_set_file [model_file] options: -l <lambda>: set regularization parameter (default 0.00002) -k <factor>: set number of latent factors (default 4) -t <iteration>: set number of iterations (default 15) ``` You should also test that it works with : `./ffm-predict` It should print: ``` usage: ffm-predict test_file model_file output_file ``` In windows and mac the behaviour should be similar. After executing `ffm-train` or `ffm-predict` from inside the `lib/your_operation_system/libffm/` you should see the same results. If you don't see this, then you need to compile it manually and drop the executables inside `lib/your_operation_system/libffm/` . You may find the follwing sources usefull: [Install libffm](https://github.com/guestwalk/libffm) . Search for `Installation ...` and `OpenMP and SSE ...` Small Note: The user would need to delete the '.mod' files from inside the `model/` folder when no longer need them. StackNet does not do that automatically as it is not possible to determine when they are not needed anymore. **IMPORTANT NOTE:** This implementation may not include all libffm features and the user is advised to use it directly from the source. Also the version may not be the final and it is not certain whether it will be updated in the future as it required manual work to find all libraries and files required that need to be included for it to run. The performance and memory consumption will also be worse than running directly . Additionally the descritpion of the parameters may not match the one in the website, hence it is advised to use libffm online parameter thread in github for more information about them. Also, multiclass problems are formed as binary 1-vs-all. ## Command Line Parameters Command | Explanation --- | --- task | could be either **regression** or **classification**.</li> sparse | True if the data to be imported are in sparse format (libsvm) or dense (false) has_head | True if train_file and test_file have headers else false model | Name of the output model file. pred_file | Name of the output prediction file. train_file | Name of the training file. test_file | Name of the test file. output_name | Prefix of the models to be printed per iteration. This is to allow the Meta features of each iteration to be printed. Defaults to nothing. data_prefix | prefix to be used when the user supplies own pairs of [X_train,X_cv] datasets for each fold as well as an X file for the whole training data. This is particularly useful for when likelihood features are needed or generally features than must be computed within cv. Each train/valid pair is identified by prefix_train[fold_index_starting_from_zero].txt/prefix_cv[fold_index_starting_from_zero].txt and prefix_train.txt for the final set. For example if prefix=mystack and folds=2 then stacknet is expecting 2 pairs of train/cv files. e.g [[mystack_train0.txt,mystack_cv0.txt],[mystack_train1.txt,mystack_cv1.txt]]. It also expects a [mystack_train.txt] for the final train set. These files can be either dense or sparse ( when 'sparse=True') and need to have the target variable in the beginning. If you use **output_name** to extract the predictions, these will be stacked vertically in the same order as the cv files. indices_name | A prefix. When given any value it prints a .csv file for each fold with the corresponding train(0) and valiation(1) indices stacked vertically .The format is “row_index,[0 if train else 1 for validation]”. First it prints the train indices and then the validation indices in exactly the same order as they appear when modelling inside StackNet. input_index (**New**) | Name of file to load in order to form the train and cv indices during kfold cross validation. This overrides the internal process for generating kfolds and ignores the given folds. Each row needs to contain an integer in that file. Row size of the file needs to be the same as the `train_file`. It should not contain headers. one line=one integer - the indice of the validation fold the case belongs to.[There is an example](/example/manual_index/EXAMPLE.MD) include_target (**New**) | True to enable printing the target column in the output file for train holdout predictions (when `output_name` is not empty). test_target | True if the test file has a target variable in the beginning (left) else false (only predictors in the file). params | Parameter file where each line is a model. empty lines correspond to the creation of new levels verbose | True if we need StackNet to output its progress else false threads | Number of models to run in parallel. This is independent of any extra threads allocated from the selected algorithms. e.g. it is possible to run 4 models in parallel where one is a randomforest that runs on 10 threads (it selected). metric | Metric to output in cross validation for each model-neuron. can be logloss, accuracy or auc (for binary only) for classification and rmse ,rsquared or mae for regerssion .defaults to 'logloss' for classification and 'rmse' for regression. stackdata | True for restacking else false seed | Integer for randomised procedures bins | A parameter that allows classifiers to be used in regression problems. It first bins (digitises) the target variable and then runs classifiers on the transformed variable. Defaults to 2</li>. folds | Number of folds for re-usable kfold ### Parameters' File In The parameter file, each line is a model. When there is an empty line then any new algorithm is used in the next level. This is a sample format. Note this file accepts comments (`#`). Anything on the right of the `#` symbol is ignored.(**New**) ``` LogisticRegression C:1 Type:Liblinear maxim_Iteration:100 scale:true verbose:false RandomForestClassifier bootsrap:false estimators:100 threads:5 logit.offset:0.00001 verbose:false cut_off_subsample:1.0 feature_subselection:1.0 gamma:0.00001 max_depth:8 max_features:0.25 max_tree_size:-1 min_leaf:2.0 min_split:5.0 Objective:ENTROPY row_subsample:0.95 seed:1 GradientBoostingForestClassifier estimators:100 threads: offset:0.00001 verbose:false trees:1 rounding:2 shrinkage:0.05 cut_off_subsample:1.0 feature_subselection:0.8 gamma:0.00001 max_depth:8 max_features:1.0 max_tree_size:-1 min_leaf:2.0 min_split:5.0 Objective:RMSE row_subsample:0.9 seed:1 Vanilla2hnnclassifier UseConstant:true usescale:true seed:1 Type:SGD maxim_Iteration:50 C:0.000001 learn_rate:0.009 smooth:0.02 h1:30 h2:20 connection_nonlinearity:Relu init_values:0.02 LSVC Type:Liblinear threads:1 C:1.0 maxim_Iteration:100 seed:1 LibFmClassifier lfeatures:3 init_values:0.035 smooth:0.05 learn_rate:0.1 threads:1 C:0.00001 maxim_Iteration:15 seed:1 NaiveBayesClassifier usescale:true threads:1 Shrinkage:0.1 seed:1 verbose:false XgboostRegressor booster:gbtree objective:reg:linear num_round:100 eta:0.015 threads:1 gamma:2.0 max_depth:4 subsample:0.8 colsample_bytree:0.4 seed:1 verbose:false XgboostRegressor booster:gblinear objective:reg:gamma num_round:500 eta:0.5 threads:1 lambda:1 alpha:1 seed:1 verbose:false RandomForestClassifier estimators=1000 rounding:3 threads:4 max_depth:6 max_features:0.6 min_leaf:2.0 Objective:ENTROPY gamma:0.000001 row_subsample:1.0 verbose:false copy=false ``` **Tip**: To tune a single model, one may choose an algorithm for the first layer and a dummy one for the second layer. StackNet expects at least two algorithms, so with this format the user can visualize the performance of single algorithm inside the K-fold. For example, if I wanted to tune a Random Forest Classifier, I would put it in the first line (layer) and also put any model (lets say Logistic Regression) in the second layer and could break the process immediately after the first layer kfold is done: ``` RandomForestClassifier bootsrap:false estimators:100 threads:5 logit.offset:0.00001 verbose:false cut_off_subsample:1.0 feature_subselection:1.0 gamma:0.00001 max_depth:8 max_features:0.25 max_tree_size:-1 min_leaf:2.0 min_split:5.0 Objective:ENTROPY row_subsample:0.95 seed:1 LogisticRegression verbose:false ``` ## Data Format For **dense** input data, the file needs to start with the target variable followed by a comma, separated variables like: 1,0,0,2,3,2.4 0,1,1,0,0,12 For **sparse** format , it is the same as libsvm (same example as above) : 1 2:2 3:3 4:2.4 0 0:1 1:1 4:12 **warning**: Some algorithms (mostly tree-based) may not be very fast with this format) If test_target is false, then the test data may not have a target and start directly from the variables. A **train** method needs at least a **train_file** and a **params_file**. It also needs at least two algorithms, and the and last layer must not contain a regressor unless the metric is auc and the problem is binary. A **predict** method needs at least a **test_file** and a **model_file**. ## Commandline Train Statement Java –jar stacknet.jar **_train_** **task=classification** **sparse**=false **has_head**=true **model**=model **pred_file**=pred.csv **train_file**=sample_train.csv **test_file**= sample_test.csv **test_target**=true **params**=params.txt **verbose**=true **threads**=7 **metric**=logloss **stackdata**=false **seed**=1 **folds**=5 **bins**=3 Note that you can have train and test at the same time. In that case after training, it scores the test data. ## Commandline predict Statement Java -jar stacknet.jar **_predict_** **sparse**=false **has_head**=true **model**=model **pred_file**=pred.csv **test_file**=sample_test.csv **test_target**=true **verbose**=true **metric**=logloss ## Examples - [Kaggle-Quora-sparse](/example/Quora_kaggle_sparse/README.MD) - [Kaggle-TwoSigma](/example/twosigma_kaggle/EXAMPLE.MD) - [Kaggle-TwoSigma Random Forest using the Library](/example/twosigma_kaggle_java_rf/EXAMPLE.MD) - [Kaggle-Amazon Classification challenge and use of data_prefix](/example/example_amazon/EXAMPLE.MD) - [Kaggle-Zillow regerssion example](/example/zillow_regression_sparse/README.MD) - [Example_with_index](/example/manual_index/EXAMPLE.MD) - [Example_H2OWorld](/example/H2OWorld_StackNet_Example/EXAMPLE.MD) ## Run StackNet from within Java code If we wanted to build a 3-level stacknet on a binary target with desne data, we start with initializing a _StackNetClassifier_ Object: ```java StackNetClassifier StackNet = new StackNetClassifier (); // Initialise a StackNet ``` Which is then followed by a 2-dimensional String array with the list of models in each layer along with their hyperparameters in the form of as in "_estimator [space delimited hyper parameters]_" ```java String models_per_level[][]=new String[][]; {//First Level {"LogisticRegression C:0.5 maxim_Iteration:100 verbose:true", "RandomForestClassifier bootsrap:false estimators:100 threads:25 offset:0.00001 cut_off_subsample:1.0 feature_subselection:1.0 max_depth:15 max_features:0.3 max_tree_size:-1 min_leaf:2.0 min_split:5.0 Objective:ENTROPY row_subsample:0.95", "LSVC C:3 maxim_Iteration:50", "LibFmClassifier maxim_Iteration:16 C:0.000001 lfeatures:3 init_values:0.9 learn_rate:0.9 smooth:0.1", "NaiveBayesClassifier Shrinkage:0.01", "Vanilla2hnnclassifier maxim_Iteration:20 C:0.000001 tolerance:0.01 learn_rate:0.009 smooth:0.02 h1:30 h2:20 connection_nonlinearity:Relu init_values:0.02", "GradientBoostingForestClassifier estimators:100 threads:25 verbose:false trees:1 rounding:2 shrinkage:0.1 feature_subselection:0.5 max_depth:8 max_features:1.0 min_leaf:2.0 min_split:5.0 row_subsample:0.9", "LinearRegression C:0.00001", "AdaboostRandomForestClassifier estimators:100 threads:3 verbose:true trees:1 rounding:2 weight_thresold:0.4 feature_subselection:0.5 max_depth:8 max_features:1.0 min_leaf:2.0 min_split:5.0 row_subsample:0.9", "GradientBoostingForestRegressor estimators:100 threads:3 trees:1 rounding:2 shrinkage:0.1 feature_subselection:0.5 max_depth:9 max_features:1.0 min_leaf:2.0 min_split:5.0 row_subsample:0.9", "RandomForestRegressor estimators:100 internal_threads:1 threads:25 offset:0.00001 verbose:true cut_off_subsample:1.0 feature_subselection:1.0 max_depth:14 max_features:0.25 max_tree_size:-1 min_leaf:2.0 min_split:5.0 Objective:RMSE row_subsample:1.0", "LSVR C:3 maxim_Iteration:50 P:0.2" }, //Second Level {"RandomForestClassifier estimators:1000 threads:25 offset:0.0000000001 verbose=false cut_off_subsample:0.1 feature_subselection:1.0 max_depth:7 max_features:0.4 max_tree_size:-1 min_leaf:1.0 min_split:2.0 Objective:ENTROPY row_subsample:1.0", "GradientBoostingForestClassifier estimators:1000 threads:25 verbose:false trees:1 rounding:4 shrinkage:0.01 feature_subselection:0.5 max_depth:5 max_features:1.0 min_leaf:1.0 min_split:2.0 row_subsample:0.9", "Vanilla2hnnclassifier maxim_Iteration:20 C:0.000001 tolerance:0.01 learn_rate:0.009 smooth:0.02 h1:30 h2:20 connection_nonlinearity:Relu init_values:0.02", "LogisticRegression C:0.5 maxim_Iteration:100 verbose:false" }, //Third Level {"RandomForestClassifier estimators:1000 threads:25 offset:0.0000000001 verbose=false cut_off_subsample:0.1 feature_subselection:1.0 max_depth:6 max_features:0.7 max_tree_size:-1 min_leaf:1.0 min_split:2.0 Objective:ENTROPY row_subsample:1.0" } }; Alternatively, we could load directly from a file : String modellings[][]=io.input.StackNet_Configuration("params.txt"); StackNet.parameters=models_per_level; // adding the models' specifications ``` The remaining parameters to be specified include the cross validation training schema, the Restacking mode option, setting a random state as well as some other miscellaneous options: ```java StackNet.threads=4; // models to be run in parallel StackNet.folds=5; // size of K-Fold StackNet.stackdata=true; // use Restacking StackNet.print=true; // this helps to avoid rerunning should the model fail StackNet.output_name="restack";// prefix for each layer's output.

Cleveroad/FanLayoutManager

Using Fan Layout Manager you can implement the horizontal list, the items of which move like fan blades

#FanLayoutManager [](https://github.com/sindresorhus/awesome) <img src="https://www.cleveroad.com/public/comercial/label-android.svg" height="20"> <a href="https://www.cleveroad.com/?utm_source=github&utm_medium=label&utm_campaign=contacts"><img src="https://www.cleveroad.com/public/comercial/label-cleveroad.svg" height="20"></a>  ## Welcome to Fan Layout Manager for Android by Cleveroad Fan Layout Manager is a new library created at Cleveroad. Our ideas don’t come from nowhere, everything we invent results from the difficulties we overcome. This exactly what happened — we were fighting uniformity! Since traditional view of the simple horizontal list isn’t impressive anymore, we decided to suggest our vision adding some colours and a completely new motion path.  #####Check out the animation <strong><a target="_blank" href="https://www.youtube.com/watch?v=P0r37_tXeMc">Fan Layout Manager for Android on YouTube</a></strong> in HD quality. Cleveroad gladly shares its creation with everyone who wants to add some visual spice to their Android apps. Take Fan Layout Manager and create! Using Fan Layout Manager you can implement the horizontal list, the items of which move like fan blades (in a circular way of a radius to your choice). To give a slightly chaotical effect to the motion, it’s possible to set an angle for the list items. So, every implementation of the library can be unique. [](https://www.cleveroad.com/?utm_source=github&utm_medium=label&utm_campaign=contacts) ### Installation ### by Gradle: ```groovy compile 'com.cleveroad:fan-layout-manager:1.0.5' ``` ### Setup and usage ### Use default FanLayoutManager in code: ```JAVA fanLayoutManager = new FanLayoutManager(getContext()); recyclerView.setLayoutManager(fanLayoutManager); ``` You can **select/deselect** item using: ```JAVA fanLayoutManager.switchItem(recyclerView, itemPosition); // select/deselect fanLayoutManager.deselectItem(); // just deselect ``` **Get selected item position**: ```JAVA fanLayoutManager.getSelectedItemPosition(); // return selected item position fanLayoutManager.isItemSelected(); // true if item was selected ``` To customize ***FanLayoutManager*** we provide settings: ```JAVA FanLayoutManagerSettings fanLayoutManagerSettings = FanLayoutManagerSettings .newBuilder(getContext()) .withFanRadius(true) .withAngleItemBounce(5) .withViewWidthDp(120) .withViewHeightDp(160) .build(); fanLayoutManager = new FanLayoutManager(getContext(), fanLayoutManagerSettings); recyclerView.setLayoutManager(fanLayoutManager); ``` `.withFanRadius(boolean isFanRadiusEnable)` - you can enable displaying items in fan style.</p> `.withAngleItemBounce(float angleItemBounce)` - added rendom bounce angle to items from [0.. angleItemBounce).</p> `.withViewWidthDp(float viewWidthDp)` - custom item width. default 120dp.</p> `.withViewHeightDp(float viewHeightDp)` - custom item height. default 160dp.</p> You can *remove bounce angle* effect for selected item: ```JAVA public void straightenSelectedItem(Animator.AnimatorListener listener); ``` and you can *restore bounce angle* effect for selected item: ```JAVA public void restoreBaseRotationSelectedItem(Animator.AnimatorListener listener) ``` You can collapse views using: ```JAVA public void collapseViews(); ``` ## Changelog See [changelog history]. ## Support If you have any questions regarding the use of this tutorial, please contact us for support at info@cleveroad.com (email subject: «FanLayoutManager for Android.

takahirom/PreLollipopTransition

Simple tool which help you to implement activity and fragment transition for pre-Lollipop devices.

# PreLollipopTransition  [](https://android-arsenal.com/api?level=14) Simple tool which help you to implement activity and fragment transition for pre-Lollipop devices.  ## Download In your app build.gradle add ```groovy dependencies { compile 'com.kogitune:pre-lollipop-activity-transition:1.x.x' } ``` [  ](https://bintray.com/takahirom/maven/PreLollipopTransition/_latestVersion) ## Code ### Activity Start Activity in first activity. ```java findViewById(R.id.imageView).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { final Intent intent = new Intent(MainActivity.this, SubActivity.class); ActivityTransitionLauncher.with(MainActivity.this).from(v).launch(intent); } }); ``` Receive intent in second activity. ```java @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_sub); ActivityTransition.with(getIntent()).to(findViewById(R.id.sub_imageView)).start(savedInstanceState); } ``` #### If you want the exit animation, you can do like this. ```java private ExitActivityTransition exitTransition; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_sub2); exitTransition = ActivityTransition.with(getIntent()).to(findViewById(R.id.sub_imageView)).start(savedInstanceState); } @Override public void onBackPressed() { exitTransition.exit(this); } ``` #### If you want to use `startActivityForResult`, you should do below. 1. Use `createBundle()`. 2. Put Extra to intent. 3. Call overridePendingTransition after `startActivityForResult`. ```java Bundle transitionBundle = ActivityTransitionLauncher.with(MainActivity.this).from(v).createBundle(); intent.putExtras(transitionBundle); startActivityForResult(intent, REQUEST_CODE); // you should prevent default activity transition animation overridePendingTransition(0, 0); ``` ### Fragment Start fragment transition in first fragment. ```java @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.support_fragment_start, container, false); v.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { final EndFragment toFragment = new EndFragment(); FragmentTransitionLauncher .with(view.getContext()) .image(BitmapFactory.decodeResource(getResources(), R.drawable.photo)) .from(view.findViewById(R.id.imageView)).prepare(toFragment); getFragmentManager().beginTransaction().replace(R.id.content, toFragment).addToBackStack(null).commit(); } }); return v; } ``` Start animation in second fragment. ```java @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.support_fragment_end, container, false); final ExitFragmentTransition exitFragmentTransition = FragmentTransition.with(this).to(v.findViewById(R.id.fragment_imageView)).start(savedInstanceState); exitFragmentTransition.startExitListening(); return v; } ``` If you want to pass argument to second fragment, you should use `Fragment#getArguments()` after call prepare(). ```java final EndFragment toFragment = new EndFragment(); FragmentTransitionLauncher .with(view.getContext()) .image(BitmapFactory.decodeResource(getResources(), R.drawable.photo)) .from(view.findViewById(R.id.imageView)).prepare(toFragment); toFragment.getArguments().putString("stringArgKey", "this is value"); getFragmentManager().beginTransaction().replace(R.id.content, toFragment).addToBackStack(null).commit(); ``` ## Sample  ## Contributors * [shiraji](http://www.github.com/shiraji) * [lovejjfg](https://github.com/lovejjfg) ## Thanks Sample Photo Luke Ma https://www.flickr.com/photos/lukema/12499338274/in/photostream/ DevBytes: Custom Activity Animations https://www.youtube.com/watch?v=CPxkoe2MraA ## License This project is released under the Apache License, Version 2.0. * [The Apache License, Version 2.0](http://www.apache.org/licenses/LICENSE-2.0)

spring-projects/spring-loaded

Java agent that enables class reloading in a running JVM

# Welcome to Spring-Loaded ## What is Spring Loaded? Spring Loaded is a JVM agent for reloading class file changes whilst a JVM is running. It transforms classes at loadtime to make them amenable to later reloading. Unlike 'hot code replace' which only allows simple changes once a JVM is running (e.g. changes to method bodies), Spring Loaded allows you to add/modify/delete methods/fields/constructors. The annotations on types/methods/fields/constructors can also be modified and it is possible to add/remove/change values in enum types. Spring Loaded is usable on any bytecode that may run on a JVM, and is actually the reloading system used in Grails 2,3,4 (on java 8). # Installation 1.3.0 has now been released! 1.3.0 Enables support for Grails 4.0.4+ Running on Java 8 (Java 11 is not yet supported and is in Development) 1.2.6 snapshots are in this repo area (grab the most recently built .jar): <a href="https://repo.spring.io/webapp/#/artifacts/browse/tree/General/libs-snapshot-local/org/springframework/springloaded/1.2.6.BUILD-SNAPSHOT">repo.spring.io</a> The download is the agent jar and needs no further unpacking before use. # Running with reloading java -javaagent:<pathTo>/springloaded-{VERSION}.jar -noverify SomeJavaClass The verifier is being turned off because some of the bytecode rewriting stretches the meaning of some of the bytecodes - in ways the JVM doesn't mind but the verifier doesn't like. Once up and running what effectively happens is that any classes loaded from jar files (dependencies) are not treated as reloadable, whilst anything loaded from .class files on disk is made reloadable. Once loaded the .class file will be watched (once a second) and should a new version appear SpringLoaded will pick it up. Any live instances of that class will immediately see the new form of the object, the instances do not need to be discarded and recreated. No doubt that raises a lot of questions and hopefully a proper FAQ will appear here shortly! But in the meantime, here are some basic Qs and As: Q. Does it reload anything that might change in a class file? A. No, you can't change the hierarchy of a type. Also there are certain constructor patterns of usage it can't actually handle right now. Q. With objects changing shape, what happens with respect to reflection? A. Reflection results change over time as the objects are reloaded. For example, modifying a class with a new method and calling `getDeclaredMethods()` after reloading has occurred will mean you see the new method in the results. *But* this does mean if you have existing caches in your system that stash reflective information assuming it never changes, those will need to be cleared after a reload. Q. How do I know when a reload has occurred so I can clear my state? A. You can write a plugin that is called when reloads occur and you can then take the appropriate action. Create an implementation of `ReloadEventProcessorPlugin` and then register it via `SpringLoadedPreProcessor.registerGlobalPlugin(plugin)`. (There are other ways to register plugins, which will hopefully get some documentation!) Q. What's the state of the codebase? A. The technology is successfully being used by Grails for reloading. It does need some performance work and a few smacks with a refactoring hammer. It needs upgrading here and there to tolerate the invokedynamic instruction and associated new constant pool entries that arrived in Java 7. # Working with the code git clone https://github.com/spring-projects/spring-loaded Once cloned there will be some projects suitable for import into eclipse. The main project and some test projects. One of the test projects is an AspectJ project (containing both Java and AspectJ code), and one is a Groovy project. To compile these test projects in Eclipse you will need the relevant eclipse plugins: AJDT: update site: `https://download.eclipse.org/tools/ajdt/42/dev/update` Groovy-Eclipse: update site: `https://dist.springsource.org/snapshot/GRECLIPSE/e4.2/` After importing them you can run the tests. There are two kinds of tests, hand crafted and generated. Running all the tests including the generated ones can take a while. To run just the hand crafted ones supply this to the JVM when launching the tests: -Dspringloaded.tests.generatedTests=false NOTE: When running the tests you need to pass `-noverify` to the JVM also. Two launch configurations are already included if you are importing these projects into eclipse, which run with or without the generated tests. A gradle build script is included, run './gradlew build' to rebuild the agent - it will be created as something like: `springloaded/build/libs/springloaded-1.3.0.BUILD-SNAPSHOT.jar` # Can I contribute? Sure! This is based on the original Spring Source Project work done by Andy Clement. As Spring was moving away from spring-loaded in favor of spring-dev-tools (a more basic alternative), Community efforts were made to update spring-loaded to work in more recent builds of Grails.

Play video in ListView or RecyclerView

listview recyclerview video-player

[](https://github.com/waynell/VideoListPlayer) [](https://jitpack.io/#waynell/VideoListPlayer) # VideoListPlayer VideoListPlayer实现了在列表控件（ListView, RecyclerView）中加载并播放视频，并支持滑动时自动播放/暂停的功能 利用该项目，可以轻松实现类似Instagram的视频播放功能 **注意：最低支持API 14以上** #效果预览   #Changelogs **v.14** 1. 支持更多类型的scaleType，详见 [Android-ScalableVideoView](https://github.com/yqritc/Android-ScalableVideoView) 2. 加入 `getCurrentPosition()` 和 `getDuration()` 接口 **v1.3** 1. fix在多类型列表元素中出现视频无法正常播放的bug **Demo 更新** 1. 增加在ListView中播放视频的示例 2. ListView和RecyclerView中支持多类型view type展示 **v1.2** 1. fix NPE bugs **v1.1** 1. 自动播放/停止功能性能优化 2. 视频播放加入声音开关控制，默认播放视频关闭声音，点击视频开启声音 3. fix在4.1.1以下无法播放视频的bug #基本用法 添加gradle依赖 repositories { maven { url "https://jitpack.io" } } dependencies { compile 'com.github.waynell:VideoListPlayer:1.4' } 在xml布局中加入以下代码 <com.waynell.videolist.widget.TextureVideoView android:id="@+id/video_view" android:layout_width="match_parent" android:layout_height="300dp" /> 然后设置视频路径地址，最后调用start()方法开始播放视频 videoView.setVideoPath(mVideoPath); videoView.start(); 视频播放是异步的，可以通过设置MediaPlayerCallback回调监听播放事件 view.setMediaPlayerCallback(this); 监听事件如下 void onPrepared(MediaPlayer mp); void onCompletion(MediaPlayer mp); void onBufferingUpdate(MediaPlayer mp, int percent); void onVideoSizeChanged(MediaPlayer mp, int width, int height); boolean onInfo(MediaPlayer mp, int what, int extra); boolean onError(MediaPlayer mp, int what, int extra); #滑动时自动播放/停止的功能 首先，你必须实现ListItem接口来获取item被激活或取消激活的事件回调 public interface ListItem { // 当前item被激活 void setActive(View newActiveView, int newActiveViewPosition); // 当前item被取消 void deactivate(View currentView, int position); } 其次，实现ItemsProvider接口返回当前列表总数和列表中某一位置的ListItem实例 public interface ItemsProvider { ListItem getListItem(int position); int listItemSize(); } 最后添加以下代码实现可见比的计算，以RecyclerView为例 ItemsProvider itemProvider; ListItemsVisibilityCalculator calculator = new SingleListViewItemActiveCalculator(itemProvider, new RecyclerViewItemPositionGetter(layoutManager, mRecyclerView);); mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() { @Override public void onScrollStateChanged(RecyclerView recyclerView, int newState) { mScrollState = newState; if(newState == RecyclerView.SCROLL_STATE_IDLE && !mListItems.isEmpty()){ mCalculator.onScrollStateIdle(); } } @Override public void onScrolled(RecyclerView recyclerView, int dx, int dy) { mCalculator.onScrolled(mScrollState); } }); # 网络视频的本地缓存 请参考demo工程的实现 #实现原理 请参见我的博客 [视频在滑动列表中的异步缓存和播放](http://blog.waynell.com/2016/03/21/video-loader/) #Thanks [VideoPlayerManager](https://github.com/danylovolokh/VideoPlayerManager) 滑动自动播放/暂停的功能基于项目优化而来

It works on Activity/Fragment/Dialog/PopupWindow or any other view. Presently, UETool provides the following functionalities: - Move any view on the screen (selecting view repeatedly will select its parent's view) - Show/edit normal view's attributes such as TextView's text, textSize, textColor etc. - Show two view's relative positions - Show grid for checking view alignment - Support Android P - Show view's current Fragment - Show activity's Fragment tree - Show view's view holder name if it exist - Easily customize any view's attributes you want simply, such as business parameters - If you are using Fresco's DraweeView, UETool shows more properties like ImageURI, PlaceHolderImage, CornerRadius etc. - If the view selected by UETool isn’t what you want, you can check ValidViews to choose which target view you want ## UETool's Effects: <div> <img width="270" height="480" src="https://github.com/eleme/UETool/blob/master/art/move_view.gif"/> <img width="270" height="480" src="https://github.com/eleme/UETool/blob/master/art/show_image_uri.gif"/> <br/> <img width="270" height="480" src="https://github.com/eleme/UETool/blob/master/art/relative_position.gif"/> <img width="270" height="480" src="https://github.com/eleme/UETool/blob/master/art/show_gridding.png"/> </div> ## ATTRIBUTE LIST | Attribute | Value Sample | Editable | | --- | --- | --- | | Move | if you checked it, you can move view easily | | | ValidViews | sometimes target view which UETool offered isn’t you want, you can check it and choose which you want | | | Class | android.widget.LinearLayout | | | Id | 0x7f0d009c | | | ResName | btn | | | Clickble | TRUE | | | Focoused | FALSE | | | Width(dp) | 107 | YES | | Height(dp) | 19 | YES | | Alpha | 1.0 | | | PaddingLeft(dp) | 10 | YES | | PaddingRight(dp) | 10 | YES | | PaddingTop(dp) | 10 | YES | | PaddingBottom(dp) | 10 | YES | | Background | #90000000 <br/> #FF8F8F8F -> #FF688FDB <br/> [PICTURE] 300px*300px | | | **TextView** | | | | Text | Hello World | YES | | TextSize(sp) | 14 | YES | | TextColor | #DE000000 | YES | | IsBold | TRUE | YES | | SpanBitmap | [PICTURE] 72px*39px | | | DrawableLeft | [PICTURE] 51px*51px | | | DrawableRight | [PICTURE] 36px*36px | | | DrawableTop | [PICTURE] 36px*36px | | | DrawableBottom | [PICTURE] 36px*36px | | | **ImageView** | | | | Bitmap | [PICTURE] 144px*144px | | | ScaleType | CENTER_CROP | | | **DraweeView** | | | | CornerRadius | 2dp | | | ImageURI | https://avatars2.githubusercontent.com/u/1201438?s=200&v=4 | | | ActualScaleType | CENTER_CROP | | | IsSupportAnimation | TRUE | | | PlaceHolderImage | [PICTURE] 300px*300px | | | | | | ## HOW TO USE ### Installation ```gradle allprojects { repositories { ... maven { url 'https://jitpack.io' } } } dependencies { debugImplementation 'com.github.eleme.UETool:uetool:1.3.4' debugImplementation 'com.github.eleme.UETool:uetool-base:1.3.4' releaseImplementation 'com.github.eleme.UETool:uetool-no-op:1.3.4' // if you want to show more attrs about Fresco's DraweeView debugImplementation 'com.github.eleme.UETool:uetool-fresco:1.3.4' } ``` ### Usage #### Show floating window ```java UETool.showUETMenu(); UETool.showUETMenu(int y); ``` #### Dismiss floating window ```java UETool.dismissUETMenu(); ``` #### Filter out unwanted views from selection ```java UETool.putFilterClass(Class viewClazz); UETool.putFilterClass(String viewClassName); ``` #### Customize your view ```java // step 1, implement IAttrs public class UETFresco implements IAttrs { @Override public List<Item> getAttrs(Element element) { } } // step 2, put in UETool UETool.putAttrsProviderClass(Class customizeClazz); UETool.putAttrsProviderClass(String customizeClassName); ``` ## License [MIT](http://opensource.org/licenses/MIT)

videlalvaro/gifsockets

Real Time communication library using Animated Gifs as a transport™

# gifsockets "This library is the websockets of the '90s" - Somebody at Hacker News. This library shows how to achieve realtime text communication using GIF images as transport.  The interesting part is that you can even use IE6 with this library and get the data in Real Time (TM). Of course this should have been delivered as an April's Fools joke but sadly we are in mid September here in the northern hemisphere. See it in action in this video: [https://vimeo.com/49447841](https://vimeo.com/49447841). ## How does it work The idea is pretty simple. We use Animated Gif images to stream data in real time to the browser. Since a gif image doesn't specify how many frames it has, once the browser opens it, it will keep waiting for new frames until you send the bits indicating that there's no more image to fetch. Pretty simple uh! And yes. It works in IE6. ## Usage The usage now is a bit rudimentary and manual. Feel free to improve it and send a PR. ```bash $ git clone git://github.com/videlalvaro/gifsockets.git $ cd gifsockets $ lein deps % lein repl ``` Then perform the following commands on the Clojure REPL. ```clojure ;; in the repl do the following to import the libs (use 'gifsockets.core) (use 'gifsockets.server) ;; ;;Then we declare the tcp server (def server (tcp-server :port 8081 :handler gif-handler)) (start2 server) ;; wait for a browser connection on port 8081 ;; go and open http://localhost:8081/ in Safari or IE6 ;; In Chrome it works a bit laggy and in Firefox it doesn't work at all ;; ;; Now let's create the gif encoder that we use to write messages to the browser. (def encoder (create-gif (.getOutputStream client))) ;; ;;Now we are ready to send messages to that browser client (add-message encoder "Hello gif-sockets") ;; now you should see a GIF image with the new message on it. (add-message encoder "Zup zup zup") (add-message encoder "And so forth") ;; ;; Now let's clean up and close the connection (.finish encoder) (.close client) ``` As you can see from the code this handles only one connection in what is called an UPoC (Uber Proof Of Concept). ## Possible uses: All joking aside I think this is a very low tech way to have say, a website where you could tail logs for instance and you need to do it with a browser that have zero websockets support or something like that. Or what about progress bars for stuff that your server is doing in the background, say, while it resizes an image? Yes. You need _gifsockets_. ## NOTE: If you need a good library for real time communications on the web then I would recommend using [sockjs](https://github.com/sockjs). ## License Copyright © 2012 Alvaro Videla The following classes: - AnimatedGifEncoder.java - GifDecoder.java - LZWEncoder.java - NeuQuant.java Were taken from this website: [http://www.fmsware.com/stuff/gif.html](http://www.fmsware.com/stuff/gif.html).

mzule/FantasySlide

Another sliding menu base on DrawerLayout

drawerlayout menubar sidebar

# FantasySlide [](https://bintray.com/mzule/maven/fantasy-slide/_latestVersion) [](https://android-arsenal.com/api?level=15) <a href="http://www.methodscount.com/?lib=com.github.mzule.fantasyslide%3Alibrary%3A1.0.4"><img src="https://img.shields.io/badge/Methods and size-core: 142 | deps: 15054 | 24 KB-e91e63.svg"/></a> [](http://android-arsenal.com/details/1/4309) 一个 DrawerLayout 的扩展,具有帅气的动画与创新的交互。一次手势完成滑出侧边栏与选择菜单。欢迎下载 demo 体验。 <https://raw.githubusercontent.com/mzule/FantasySlide/master/demo.apk> ## 效果  ## 使用方法 ### 添加依赖 ``` groovy compile 'com.github.mzule.fantasyslide:library:1.0.5' ``` ### 调用 调用方法基本与 DrawerLayout 一致. 本项目支持左右 (start left end right) 侧边栏同时定义。 ``` xml <com.github.mzule.fantasyslide.FantasyDrawerLayout xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/drawerLayout" android:layout_width="match_parent" android:layout_height="match_parent"> <ImageView android:layout_width="match_parent" android:layout_height="match_parent" android:scaleType="centerCrop" android:src="@drawable/fake" /> <com.github.mzule.fantasyslide.SideBar android:id="@+id/leftSideBar" android:layout_width="200dp" android:layout_height="match_parent" android:layout_gravity="start" android:background="@color/colorPrimary" app:maxTranslationX="66dp"> <!-- 这里是 SideBar 的子视图--> </com.github.mzule.fantasyslide.SideBar> <!-- 如果需要的话，可以添加右侧边栏--> </com.github.mzule.fantasyslide.FantasyDrawerLayout> ``` 1. 最外层的 FantasyDrawerLayout 的使用与官方的 DrawerLayout 完全一致。 2. SideBar 用来包装每一个菜单项，SideBar 本质上可以当做一个 vertical 的 LinearLayout 来使用。 3. 效果图上的文字变色是表示该菜单处于 hover 状态, hover 状态默认会设定 view 的 pressed 状态为 true。可以通过 Listener 来改写, 下文会有详细说明。 4. 详细参考 <https://github.com/mzule/FantasySlide/blob/master/app/src/main/res/layout/activity_main.xml> ## 进阶 ### maxTranslationX 通过设置 maxTranslationX 可以设置菜单项动画的最大位移。仅有在采用默认 Transformer 时才有效。 ``` xml <com.github.mzule.fantasyslide.SideBar ... app:maxTranslationX="88dp"> ``` 一般情况下，左边的侧边栏 maxTranslationX 为正数，右边的侧边栏 maxTranslationX 为负数。 ### Listener 支持设置 Listener 来监听侧边栏菜单的状态。 ``` java SideBar leftSideBar = (SideBar) findViewById(R.id.leftSideBar); leftSideBar.setFantasyListener(new SimpleFantasyListener() { @Override public boolean onHover(@Nullable View view) { return false; } @Override public boolean onSelect(View view) { return false; } @Override public void onCancel() { } }); ``` 1. Hover 是指上面效果图中，高亮的状态，此时手指仍在屏幕上 move. 默认的 hover 处理逻辑是设置 view 的 pressed 状态为 true. 重写 onHover(View) 方法返回 true 可以改写默认逻辑。 2. Select 是指 hover 状态时手指离开屏幕，触发 select 状态。默认的处理逻辑是调用 view 的 onClick 事件。重写 onSelect(View) 方法返回 true 可以改写默认逻辑。 3. Cancel 是指手指离开屏幕时，没有任何 view 触发 select 状态，则为 cancel，无默认处理逻辑。 ### Transformer 项目设计了一个 Transformer 接口，供调用者自定义菜单项的动画效果。使用方法类似于 ViewPager 的 PageTransformer. ``` java class DefaultTransformer implements Transformer { private float maxTranslationX; DefaultTransformer(float maxTranslationX) { this.maxTranslationX = maxTranslationX; } @Override public void apply(ViewGroup sideBar, View itemView, float touchY, float slideOffset, boolean isLeft) { float translationX; int centerY = itemView.getTop() + itemView.getHeight() / 2; float distance = Math.abs(touchY - centerY); float scale = distance / sideBar.getHeight() * 3; // 距离中心点距离与 sideBar 的 1/3 对比 if (isLeft) { translationX = Math.max(0, maxTranslationX - scale * maxTranslationX); } else { translationX = Math.min(0, maxTranslationX - scale * maxTranslationX); } itemView.setTranslationX(translationX * slideOffset); } } ``` ## 感谢 动画效果参考自 dribbble. <https://dribbble.com/shots/2269140-Force-Touch-Slide-Menu> 在此感谢。 另外，demo 里面 MainActivity 的右边栏实现了类似原作的菜单动画效果。具体可以参考相关代码。 ## 许可 Apache License 2.0 ## 联系我 任何相关问题都可以通过以下方式联系我。 1. 提 issue 1. 新浪微博 http://weibo.com/mzule 1. 个人博客 https://mzule.github.io/ 1. 邮件 "mzule".concat("4j").concat("@").concat("gmail.com")

jfree/jfreechart

A 2D chart library for Java applications (JavaFX, Swing or server-side).

charts data-visualization java2d javafx swing

JFreeChart ========== Version 2.0.0, not yet released. [](https://maven-badges.herokuapp.com/maven-central/org.jfree/jfreechart) Overview -------- JFreeChart is a comprehensive free chart library for the Java&#8482; platform that can be used on the client-side (JavaFX and Swing) or the server side, with export to multiple formats including SVG, PNG and PDF.  The home page for the project is: http://www.jfree.org/jfreechart JFreeChart requires JDK 11 or later. For Java 8 support, check the `v1.5.x` branch. The library is licensed under the terms of the GNU Lesser General Public License (LGPL) version 2.1 or later. JavaFX ------ JFreeChart can be used with JavaFX via the `JFreeChart-FX` extensions: https://github.com/jfree/jfreechart-fx Demos ----- A small set of demo applications can be found in the following projects here at GitHub: * [JFree-Demos](https://github.com/jfree/jfree-demos "JFree-Demos Project Page at GitHub") * [JFree-FXDemos](https://github.com/jfree/jfree-fxdemos "JFree-FXDemos Project Page at GitHub") A more comprehensive set of demos, plus the JFreeChart Developer Guide, is a reward at most tiers of the [JFree sponsorship](https://github.com/sponsors/jfree) program. Thanks for supporting the JFree projects! For Developers -------------- ### Using JFreeChart To use JFreeChart in your projects, add the following dependency to your build tool: <dependency> <groupId>org.jfree</groupId> <artifactId>jfreechart</artifactId> <version>1.5.3</version> </dependency> ### Building JFreeChart You can build JFreeChart using Maven by issuing the following command from the root directory of the project: mvn clean install The build requires JDK 11 or later. ### Migration When migrating from JFreeChart 1.0.x to JFreeChart 1.5.0, please be aware of the following API changes: * all the classes from JCommon that are used by JFreeChart have integrated within the JFreeChart jar file within a different package than before (you will need to change your imports); * many methods `getBaseXXX()/setBaseXXX()` have been renamed `setDefaultXXX()/getDefaultXXX()`; * the `ChartUtilities` class has been renamed `ChartUtils`; * all the classes relating to pseudo-3D charts have been removed, as much better 3D charts are offered by [Orson Charts](https://github.com/jfree/orson-charts) so we prefer not to maintain the pseudo-3D chart code within JFreeChart; * the `SegmentedTimeline` class has been removed due to being (a) complex, (b) not always being correct and, as a result, generating too many support requests; * the `org.jfree.chart.utils.ParamChecks` class has been renamed `org.jfree.chart.utils.Args`. Please refer to [Issue 66](https://github.com/jfree/jfreechart/issues/66) for additional info. History ------- ##### Version 2.0 (not yet released) - use `ThreadLocal` for calendars in time series datasets ([#171](https://github.com/jfree/jfreechart/pull/171)); - added `valueVisible` flag to `MeterPlot` ([#231](https://github.com/jfree/jfreechart/pull/231));

The session is scheduled for 6.45pm to 7.35pm on Wednesday 3 June. This release contains: - updates to the `ChartPanel` class to support copying charts to the clipboard, panning and mouse-wheel zooming, and an overlay mechanism that supports crosshairs; - enhancements to the auto-range calculation for axes, providing the ability to use subranges only and also to skip hidden series; - updates for many of the `CategoryItemRenderer` implementations to ensure that they respect the `seriesVisible` flags; - an improvement to the `TimeSeries` class so that it is no longer necessary to specify the time period type in the constructor; - a new `SamplingXYLineRenderer` for improving the performance of time series charts with large datasets; - the `XYSeries/XYSeriesCollection` classes now cache the minimum and maximum data values to improve the performance of charts with large datasets; - entities are now created for the chart, data area and axes, allowing mouse clicks to be detected for these regions; - added a bar alignment factor to the `XYBarRenderer` class; - a new `errorIndicatorStroke` field for the `StatisticalLineAndShapeRenderer` and `XYErrorRenderer` classes; - added a new `HeatMapDataset` interface, `DefaultHeatMapDataset` implementation, and a `HeatMapUtilities` class to make it easier to create heat map charts; - there is a new flag to allow an `XYDataImageAnnotation` to be included in the automatic range calculation for the axes; - additional attributes in the `XYTextAnnotation` class; - added a `sampleFunction2DToSeries()` method to the `DatasetUtilities` class; - some changes to the `ChartPanel` class that help to work around a regression in JRE 1.6.0_10 relating to drawing in XOR mode. Regarding this final point: * the default value for the `useBuffer` flag has changed to true, which means that all charts will, by default, be rendered into an off-screen image before being displayed in the `ChartPanel`; * the zoom rectangle is drawn using XOR mode *only* when the `useBuffer` flag has been set to false. For most usage, this should improve performance (but at the cost of using more memory for each `ChartPanel` used in your application); ###### Bug Fixes - 2690293 : Problem with Javascript escape characters; - 2617557 : `StandardDialScale` ignored `tickLabelPaint`; - 2612649 : `Stroke` selection in plot property editor; - 2583891 : `SWTGraphics2D.fillPolygon()` not implemented; - 2564636 : `Month` constructor ignores Locale; - 2502355 : `ChartPanel` sending multiple events; - 2490803 : `PeriodAxis.setRange()` method doesn't take into account that the axis displays whole periods; In addition, a bug in the `SlidingCategoryDataset` class has been fixed, the correct outline paint is now used by `GradientXYBarPainter`, a new method has been added to the `ImageMapUtilities` class to escape special characters in Javascript strings to avoid problems with the OverLIB and DynamicDrive tooltips, and there are some important fixes in the `LogAxis` class.

The Data Transfer Project makes it easy for people to transfer their data between online service providers. We are establishing a common framework, including data models and protocols, to enable direct transfer of data both into and out of participating online service providers.

data data-portability portability transfer

# Data Transfer Project ## Overview The Data Transfer Project makes it easy for people to transfer their data between online services. We provide a common framework and ecosystem to accept contributions from service providers to enable seamless transfer of data into and out of their service. ## Who We Are Data Transfer Project (DTP) is a collaboration of organizations committed to building a common framework with open-source code that can connect any two online service providers, enabling a seamless, direct transfer of data. We want all individuals across the web to be in control of their data. ## More info * [Repository master branch](https://github.com/google/data-transfer-project) * [Developer documentation](Documentation/Developer.md) * [Contributing](CONTRIBUTING.md) * [Code of Conduct](CODE_OF_CONDUCT.md) ## Current State Data Transfer Project is in its early stages, and we are actively looking for partner organizations and individuals to contribute to the project. We are continuing to define the architecture and implementation. Since the code is in active development, please do thorough testing and verification before implementing. ## Contact Info Please contact [dtp-discuss@googlegroups.com](mailto:dtp-discuss@googlegroups.com) with any questions or comments. ## About Us The Data Transfer Project was formed in 2017 to create an open-source, service-to-service portability platform so that all individuals across the web could easily move their data between online service providers. The partners in the Data Transfer Project believe portability and interoperability are central to innovation. Making it easier for individuals to choose among services facilitates competition, empowers individuals to try new services and enables them to choose the offering that best suits their needs. We anticipate the Data Transfer Project solution will make a particularly big impact in global markets where downloading or uploading data is expensive and/or slow. The Data Transfer Project eliminates the need to download data at all. Instead, data is transferred directly between service providers. #### DTP is early-stage open source code that is built and maintained entirely by DTP community members.

zmxv/react-native-sound

React Native module for playing sound clips

# react-native-sound [][npm] [][npm] [][npm] [npm]: https://www.npmjs.com/package/react-native-sound React Native module for playing sound clips on iOS, Android, and Windows. Be warned, this software is alpha quality and may have bugs. Test on your own and use at your own risk! ## Feature matrix React-native-sound does not support streaming. See [#353][] for more info. Of course, we would welcome a PR if someone wants to take this on. In iOS, the library uses [AVAudioPlayer][], not [AVPlayer][]. [#353]: https://github.com/zmxv/react-native-sound/issues/353 [AVAudioPlayer]: https://developer.apple.com/documentation/avfoundation/avaudioplayer [AVPlayer]: https://developer.apple.com/documentation/avfoundation/avplayer Feature | iOS | Android | Windows ---|---|---|--- Load sound from the app bundle | ✓ | ✓ | ✓ Load sound from other directories | ✓ | ✓ | ✓ Load sound from the network | ✓ | ✓ | Play sound | ✓ | ✓ | ✓ Playback completion callback | ✓ | ✓ | ✓ Pause | ✓ | ✓ | ✓ Resume | ✓ | ✓ | ✓ Stop | ✓ | ✓ | ✓ Reset | | ✓ | Release resource | ✓ | ✓ | ✓ Get duration | ✓ | ✓ | ✓ Get number of channels | ✓ | | Get/set volume | ✓ | ✓ | ✓ Get system volume | ✓ | ✓ | Set system volume | | ✓ | Get/set pan | ✓ | | Get/set loops | ✓ | ✓ | ✓ Get/set exact loop count | ✓ | | Get/set current time | ✓ | ✓ | ✓ Set speed | ✓ | ✓ | ## Installation First install the npm package from your app directory: ```javascript npm install react-native-sound --save ``` Note: If your react-native version is >= 0.60 then linking is done automatically. If your react-native version is < 0.60 then link it using: ```javascript react-native link react-native-sound ``` **If you encounter this error** ``` undefined is not an object (evaluating 'RNSound.IsAndroid') ``` you may additionally need to fully clear your build caches for Android. You can do this using ```bash cd android ./gradlew cleanBuildCache ``` After clearing your build cache, you should execute a new `react-native` build. If you still experience issues, **know that this is the most common build issue.** See [#592][] and the several issues linked from it for possible resolution. A pull request with improved documentation on this would be welcome! [#592]: https://github.com/zmxv/react-native-sound/issues/592 ### Manual Installation Notes Please see the Wiki for these details https://github.com/zmxv/react-native-sound/wiki/Installation ## Help with React-Native-Sound * For react-native-sound developers [![][gitter badge]](https://gitter.im/react-native-sound/developers) * For help using react-native-sound [![][gitter badge]](https://gitter.im/react-native-sound/Help) [gitter badge]: https://img.shields.io/gitter/room/react-native-sound/developers.svg?format=flat-square ## Demo project https://github.com/zmxv/react-native-sound-demo ## Player <img src="https://github.com/benevbright/react-native-sound-playerview/blob/master/docs/demo.gif?raw=true"> https://github.com/benevbright/react-native-sound-playerview ## Basic usage First you'll need to add audio files to your project. - Android: Save your sound clip files under the directory `android/app/src/main/res/raw`. Note that files in this directory must be lowercase and underscored (e.g. my_file_name.mp3) and that subdirectories are not supported by Android. - iOS: Open Xcode and add your sound files to the project (Right-click the project and select `Add Files to [PROJECTNAME]`) ```js // Import the react-native-sound module var Sound = require('react-native-sound'); // Enable playback in silence mode Sound.setCategory('Playback'); // Load the sound file 'whoosh.mp3' from the app bundle // See notes below about preloading sounds within initialization code below. var whoosh = new Sound('whoosh.mp3', Sound.MAIN_BUNDLE, (error) => { if (error) { console.log('failed to load the sound', error); return; } // loaded successfully console.log('duration in seconds: ' + whoosh.getDuration() + 'number of channels: ' + whoosh.getNumberOfChannels()); // Play the sound with an onEnd callback whoosh.play((success) => { if (success) { console.log('successfully finished playing'); } else { console.log('playback failed due to audio decoding errors'); } }); }); // Reduce the volume by half whoosh.setVolume(0.5); // Position the sound to the full right in a stereo field whoosh.setPan(1); // Loop indefinitely until stop() is called whoosh.setNumberOfLoops(-1); // Get properties of the player instance console.log('volume: ' + whoosh.getVolume()); console.log('pan: ' + whoosh.getPan()); console.log('loops: ' + whoosh.getNumberOfLoops()); // Seek to a specific point in seconds whoosh.setCurrentTime(2.5); // Get the current playback point in seconds whoosh.getCurrentTime((seconds) => console.log('at ' + seconds)); // Pause the sound whoosh.pause(); // Stop the sound and rewind to the beginning whoosh.stop(() => { // Note: If you want to play a sound after stopping and rewinding it, // it is important to call play() in a callback. whoosh.play(); }); // Release the audio player resource whoosh.release(); ``` ## Notes - To minimize playback delay, you may want to preload a sound file without calling `play()` (e.g. `var s = new Sound(...);`) during app initialization. This also helps avoid a race condition where `play()` may be called before loading of the sound is complete, which results in no sound but no error because loading is still being processed. - You can play multiple sound files at the same time. Under the hood, this module uses `AVAudioSessionCategoryAmbient` to mix sounds on iOS. - You may reuse a `Sound` instance for multiple playbacks. - On iOS, the module wraps `AVAudioPlayer` that supports aac, aiff, mp3, wav etc. The full list of supported formats can be found at https://developer.apple.com/library/content/documentation/MusicAudio/Conceptual/CoreAudioOverview/SupportedAudioFormatsMacOSX/SupportedAudioFormatsMacOSX.html - On Android, the module wraps `android.media.MediaPlayer`. The full list of supported formats can be found at https://developer.android.com/guide/topics/media/media-formats.html - On Android, the absolute path can start with '/sdcard/'. So, if you want to access a sound called "my_sound.mp3" on Downloads folder, the absolute path will be: '/sdcard/Downloads/my_sound.mp3'. - You may chain non-getter calls, for example, `sound.setVolume(.5).setPan(.5).play()`. ## Audio on React Native - [The State of Audio Libraries in React Native (Oct. 2018)][medium] - [react-native-audio-toolkit][] - [react-native-video][] (also plays audio) - [Expo Audio SDK][] - [#media on awesome-react-native][#media] [medium]: https://medium.com/@emmettharper/the-state-of-audio-libraries-in-react-native-7e542f57b3b4 [react-native-audio-toolkit]: https://github.com/react-native-community/react-native-audio-toolkit [react-native-video]: https://github.com/react-native-community/react-native-video [expo audio sdk]: https://docs.expo.io/versions/latest/sdk/audio/ [#media]: http://www.awesome-react-native.com/#media ## Contributing Pull requests welcome with bug fixes, documentation improvements, and enhancements.

VoltDB/voltdb

Volt Active Data

What is Volt Active Data? ==================== Thank you for your interest in Volt Active Data! Volt Active Data provides reliable data services for today's demanding applications. A distributed, horizontally-scalable, ACID-compliant database that provides streaming, storage, and real-time analytics for applications that benefit from strong consistency, high throughput and low, predictable latency. Volt Active Data and Open Source ==================== 2023: Volt Active Data’s Open Source version is now frozen -------------------- At the end of 2022 we stopped updating this Github repo. While this code exists, and can be used, it is not an ‘official’ version of Volt. It does not receive updates. We will not provide any form of support for it, and if you end up buying Volt you will need to move to the official version. Evaluating Volt using this version -------------------- This version is provided for students, hobbyists, and researchers interested in testing an ultra-fast, scalable ACID database. But all new and production-ready features are available through the commercial product from https://www.voltactivedata.com. If you are looking at using Volt in a real-world business context, then we would strongly recommend that you speak to us directly. We have lots of experience helping people evaluate data platforms, and can set you up with demonstration clusters on AWS running representative workloads. We know from experience that this drastically cuts down the time needed to get to a ‘Go/No Go’ decision. Bear in mind that a lot of our customers are doing complicated things like cross center data replication, kubernetes or very high transactions per second, and we can help you see these features in action without you having to build a deployment from scratch. Different Versions -------------------- Volt Active Data offers the fully open source, AGPL3-licensed Community Edition of Volt Active Data through GitHub here: https://github.com/voltdb/voltdb/ Trials of the enterprise edition of Volt Active Data are available from the Volt Active Data website at the following URL: https://www.voltactivedata.com The Community Edition has full application compatibility and provides everything needed to run a real-time, in-memory SQL database with datacenter-local redundancy and snapshot-based disk persistence. The commercial editions add operational features to support industrial-strength durability, manageability, and availability, including per-transaction disk-based persistence, multi-datacenter replication, elastic online expansion, live online upgrade, etc. For more information, please visit the Volt Active Data website. https://voltactivedata.com VoltDB Branches and Tags ==================== The latest development branch is _master_. We develop features on branches and merge to _master_ when stable. While _master_ is usually stable, it should not be considered production-ready and may also have partially implemented features. Code that corresponds to released versions of Volt Active Data are tagged "voltdb-X.X" or "voltdb-X.X.X". To build corresponding OSS VoltDB versions, use these tags. Building Volt Active Data ==================== Information on building Volt Active Data from this source repository is maintained in a GitHub wiki page available here: https://github.com/VoltDB/voltdb/wiki/Building-VoltDB First Steps ==================== From the directory where you installed Volt Active Data, you can either use bin/{command} or add the bin folder to your path so you can use the Volt Active Data commands anywhere. For example: PATH="$PATH:$(pwd)/bin/" voltdb --version Then, initialize a root directory and start a single-server database. By default the root directory is created in your current working directory. Or you can use the --dir option to specify a location: voltdb init [--dir ~/mydb] voltdb start [--dir ~/mydb] [--background] To start a SQL console to enter SQL DDL, DML or DQL: sqlcmd To launch the web-based Volt Management Console (VMC), open a web browser and connect to localhost on port 8080 (unless there is a port conflict): http://localhost:8080. To stop the running Volt Active Data cluster, use the shutdown command. For commercial customers, the database contents are saved automatically by default. For open-source users, add the --save argument to manually save the contents of your database: voltadmin shutdown [--save] Then you can simply use the start command to restart the database: voltdb start [--dir ~/mydb] [--background] Further guidance can be found in the tutorial: https://docs.voltactivedata.com/tutorial/. For more on the CLI, see the documentation: https://docs.voltactivedata.com/UsingVoltDB/clivoltdb.php. Next Steps ==================== ### Examples You can find application examples in the "examples" directory inside this Volt Active Data kit. The Voter app ("examples/voter") is a great example to start with. See the README to learn what it does and how to get it running. The "examples" directory provides additional examples and a README explaining how to run them. ### Tutorial The Volt Active Data Tutorial walks you through building and running your first Volt Active Data application. https://docs.voltactivedata.com/tutorial/ ### Documentation The _Using VoltDB_ guide and supporting documentation is comprehensive and easy to use. It's a great place for broad understanding or to look up something specific. https://docs.voltactivedata.com/ ### Go Full Cloud For information on using VoltDB in the Cloud, see the _Volt Kubernetes Administrator's Guide_. https://docs.voltactivedata.com/KubernetesAdmin/ What's Included ==================== If you have installed Volt Active Data from the distribution kit, you now have a directory containing this README file and several subdirectories, including: - **bin** - Scripts for starting Volt Active Data, bulk loading data, as well as interacting with and managing the running database. Including: - bin/voltdb - Start a Volt Active Data process. - bin/voltadmin - CLI to manage a running cluster. - bin/sqlcmd - SQL console. - **doc** - Documentation, tutorials, and java-doc - **examples** - Sample programs demonstrating the use of Volt Active Data - **lib** - Third party libraries - **tools** - XML schemas, monitoring plugins, and other tools - **voltdb** - the Volt Active Data binary software itself including: - log4j files - Logging configuration. - voltdbclient-version.jar - Java/JVM client for connecting to VoltDB, including native Volt Active Data client and JDBC driver. - voltdb-version.jar - The full Volt Active Data binary, including platform-specific native libraries embedded within the jar. This is a superset of the client code and can be used as a native client driver or JDBC driver. Commercial Volt Active Data Differences ==================== Volt Active Data offers sandboxes and a pre-built trial version of Volt Active Data for application developers who want to try out the product. See the Volt Active Data website for more information. https://voltactivedata.com/ Getting Help & Providing Feedback ==================== If you have any questions or comments about Volt Active Data, we encourage you to reach out to the Volt Active Data team and community through stack overflow: https://stackoverflow.com/questions/tagged/voltdb.

Level-of-Detail renderer in Minecraft. Allows for render distances of millions of blocks. (Cubic Chunks-compatible) (WIP)

cubic-chunks cubicchunks forge minecraft

# FarPlaneTwo [](https://jenkins.daporkchop.net/job/PorkStudios/job/FarPlaneTwo/)   [](https://discord.gg/FrBHHCk) [](https://www.patreon.com/DaPorkchop_) This is a Minecraft mod which implements a Level-of-Detail (LoD) terrain renderer into the game. The name is in reference to [Foghrye4's CWGFarPlaneView](https://www.curseforge.com/minecraft/mc-mods/cwg-far-plane-view), which is an addon for CubicWorldGen (which, in turn, is an addon for Cubic Chunks) which renders a plane at sea level with block and biome colors, and served as the original inspiration for me to make this. **This mod is a work in progress! If you do decide to download this, don't expect stuff to work correctly because it probably won't.** **Remember to [Read the FAQ first](https://github.com/PorkStudios/FarPlaneTwo/wiki/FAQ)**! ## Installation *This is a Forge mod for Minecraft 1.12.2. Other versions WILL be supported in the future.* 1) Install [Minecraft Forge](https://files.minecraftforge.net/net/minecraftforge/forge/index_1.12.2.html) for Minecraft 1.12.2. 2) [Download](https://jenkins.daporkchop.net/job/PorkStudios/job/FarPlaneTwo/job/master/) the mod. 3) Download these dependencies too: - [ForgeRocks](https://www.curseforge.com/minecraft/mc-mods/forgerocks) - [Mixin](https://www.curseforge.com/minecraft/mc-mods/mixin-0-7-0-8-compatibility) For best results use cubic chunks and cubic world gen and set the world type to custom cubic. (Cubic Chunks bundles Mixin inside it, so don't use both cubic chunks and mixin together.) - [Cubic Chunks](https://jenkins.daporkchop.net/job/OpenCubicChunks/job/CubicChunks/) - [Cubic World Gen](https://jenkins.daporkchop.net/job/OpenCubicChunks/job/CubicWorldGen/) Some of the above pages should look a lot like this:  There can be a lot of links on these pages. Click on the first one underneath "Last Successful Artifacts". ## Goals and Motivations My end goal is to achieve the following: - be able to use render distances of *at least* 100 thousand blocks - cause at most a 25% decrease in performance when using my i5-2520M's integrated graphics - be compatible with [Cubic Chunks](https://github.com/OpenCubicChunks/CubicChunks) - be as compatible as reasonably possible with other mods I have exactly zero concern with doing stuff that is unsafe: for instance, [the client-side render tree](https://github.com/PorkStudios/FarPlaneTwo/blob/master/src/main/java/net/daporkchop/fp2/mode/common/client/FarRenderTree.java), which the renderer traverses when deciding which tiles to render each frame, is implemented entirely using off-heap memory. At some point (once the internals of the mod are more polished) I'll probably write up a big section here describing exactly how a lot of the stuff works.

[](https://github.com/w3c/epubcheck/releases/latest) [](https://github.com/w3c/epubcheck/releases/) [](https://github.com/w3c/epubcheck/actions/workflows/maven-ci.yml?query=branch%3Amain) EPUBCheck ========= EPUBCheck is the official conformance checker for EPUB publications. EPUBCheck can be run as a standalone command-line tool or used as a Java library. EPUBCheck is open source software, maintained by the [DAISY Consortium](http://www.daisy.org) on behalf of [W3C](https://www.w3.org/publishing/epubcheck_fundraising). **We Need Your Support!!** Financial support is critical to the development of EPUBCheck, the tool we all use to validate EPUB files. We need to make sure that the resources are adequate to both update the tool and provide for its continued maintenance over the next two years; please [help us fund and support EPUBCheck](https://www.w3.org/publishing/epubcheck_fundraising), and join the [list of donators](#donators)! ## Downloads Check the [releases page](https://github.com/w3c/epubcheck/releases) to get the latest distribution. [EPUBCheck v5.1.0](https://github.com/w3c/epubcheck/releases/tag/v5.1.0) is the latest production-ready release, to be used to validate both EPUB 2 and 3 files. EPUB 3 publications are checked against the [EPUB 3.3](https://www.w3.org/TR/epub-33/) specification. ## Documentation Documentation on how to **use** EPUBCheck, to **contribute** to the project or to **translate** messages is available on the [EPUBCheck wiki](https://github.com/w3c/epubcheck/wiki). Technical discussions are held on our public [mailing list](https://lists.w3.org/Archives/Public/public-epubcheck/). To subscribe to the mailing list, send an email with subject `subscribe` to [public-epubcheck-request@w3.org](mailto:public-epubcheck-request@w3.org?subject=subscribe). To participate in the discussion, simply send an email to [public-epubcheck@w3.org](mailto:public-epubcheck-request@w3.org). Historical archives of discussions prior to October 2017 are stored at the old [EPUBCheck Google Group](https://groups.google.com/forum/#!forum/epubcheck). ## Building EPUBCheck ### Build from sources To build epubcheck from the sources you need Java Development Kit (JDK) 1.7 or above and [Apache Maven](http://maven.apache.org/) 3.0 or above installed. Build and run tests: ``` $ mvn clean install ``` Will copy `*.jar` files and packages to `target/` folder... ### Build using docker To build the epubcheck using docker, use the build command below: ```bash $ docker build . -t epubcheck ``` To run the epubcheck image as container, use example command below: ```bash # one directory in the host need to be mapped (using docker volume) to /data path # within container. the particular path will be used as a bridge to enable access # over the epub file or the generated output file between host and container. $ docker run -it --rm -v <directory>:/data epubcheck --help $ docker run -it --rm -v <directory>:/data epubcheck <epub-file> [OPTIONS] # example 1: # execute an epub check over a file located in /home/username/file.epub on the host. # the output will be printed to the console $ docker run -it --rm -v /home/username:/data epubcheck file.epub # example 2: # execute an epub check over a file, and then generate an output file # in /data/output.json within container. # since /data is mapped via volume, then the generated file will be accessible # from /home/username/output.json in the host $ docker run - --rm -v /home/username:/data epubcheck file.epub --json output.json ``` ## Credits EPUBCheck v5.1.0 was developed by [the DAISY Consortium](https://www.daisy.org/), on behalf of W3C. Initial EPUBCheck development was largely done at [Adobe](https://www.adobe.com/). A significant part of EPUBCheck functionality comes from the schema validation tool [Jing](https://relaxng.org/jclark/jing.html), used with schemas from the [Nu HTML Checker](https://validator.github.io/validator/), [IDPF](https://idpf.org), and [DAISY](https://www.daisy.org/). Past and present EPUBCheck developers include: Romain Deltour, Matt Garrish, Tobias Fischer, Markus Gylling, Steve Antoch, Peter Sorotokin, Thomas Ledoux, Masayoshi Takahashi, Paul Norton, Piotr Kula, Arwen Pond, Liza Daly, Garth Conboy, and [several others](https://github.com/w3c/epubcheck/graphs/contributors). Many thanks to the numerous people who have contributed to the evolution of EPUBCheck through bug reports, pull requests, and translations! ## Donators The following organizations are supporting the development of EPUBCheck by their contribution to the [fundraising initiative](https://www.w3.org/publishing/epubcheck_fundraising): <p float="left"> <a href="https://www.macmillanlearning.com"><img alt="MacMillan Learning" src="https://www.w3.org/publishing/donators_logos/MacLearn_logo_cmyk.png" width="200" hspace="20" align="middle"/></a> <a href="https://www.google.com"><img alt="Google" src="https://www.w3.org/publishing/donators_logos/Google.png" width="400" hspace="20" align="middle"/></a> <a href="http://daisy.org"><img alt="DAISY" src="https://www.w3.org/publishing/donators_logos/daisy_high.jpg" width="100" hspace="20" align="middle"/></a> <a href="https://pubhub.dk"><img alt="Publizon A/S" src="https://www.w3.org/publishing/donators_logos/publizon-logo.jpg" width="100" hspace="20" align="middle"/></a> <a href="https://www.wiley.com"><img alt="Wiley" src="https://www.w3.org/publishing/donators_logos/Wiley_Wordmark_black.png" width="200" hspace="20" align="middle"/></a> <a href="https://www.hachette.com"><img alt="Hachette Livre" src="https://www.w3.org/publishing/donators_logos/Hachette%20Livre.jpg" width="300" hspace="20" align="middle"/></a> <a href="https://www.learningmate.com"><img alt="LearningMate Solutions Inc" src="https://www.w3.org/publishing/donators_logos/LearningMate%20Logo.png" width="100" hspace="20" align="middle"/></a> <a href="https://www.voyager.co.jp"><img alt="Voyager Japan, Inc." src="https://www.w3.org/publishing/donators_logos/rectangle_VJstar_logo_512.jpg" width="100" hspace="20" align="middle"/></a> <a href="https://qainfotech.com"><img alt="QA Info Tech" src="https://www.w3.org/publishing/donators_logos/QA%20InfoTech%20Logo%20PNG%20Format.png" width="200" hspace="20" align="middle"/></a> <a href="https://wwnorton.com"><img alt="W.

TypeDB: the polymorphic database powered by types

database inference knowledge-base knowledge-representation logic polymorphic polymorphism reasoning strongly-typed type-system typedb typeql

[](https://typedb.com/introduction) [](https://factory.vaticle.com/vaticle/typedb) [](https://circleci.com/gh/vaticle/typedb/tree/master) [](https://github.com/vaticle/typedb/releases/latest) [](https://typedb.com/discord) [](https://forum.typedb.com) [](https://stackoverflow.com/questions/tagged/typedb) [](https://stackoverflow.com/questions/tagged/typeql) [](https://cloudsmith.com) # Introducing TypeDB TypeDB is a [polymorphic](https://typedb.com/features#polymorphic-queries) database with a [conceptual](https://typedb.com/features#conceptual-modeling) data model, a strong [subtyping](https://typedb.com/features#strong-type-system) system, a symbolic [reasoning](https://typedb.com/features#symbolic-reasoning) engine, and a beautiful and elegant [type-theoretic](https://typedb.com/features#modern-language) language [TypeQL](https://github.com/vaticle/typeql). > **IMPORTANT NOTE:** > > TypeDB & TypeQL are in the process of being rewritten in [Rust](https://www.rust-lang.org). There will be significant refinement to the language, and minor breaks in backwards compatibility. Learn about the changes on our [roadmap issue on GitHub](https://github.com/vaticle/typedb/issues/6764). The biggest change to TypeDB 3.0 will be our storage data structure and architecture that significantly boosts performance. We’re aiming to release 3.0 in the summer this year, along with preliminary benchmarks of TypeDB. ## Polymorphic databases ### Why TypeDB was built Data frequently exhibits polymorphic features in the form of inheritance hierarchies and interface dependencies. TypeDB was crafted to solve the inability of current database paradigms to natively express these polymorphic features. - Relational schemas have [no native capability for modeling polymorphic data](https://typedb.com/philosophy#why-do-we-need-a-polymorphic-database). - Unstructured databases eliminate the schemas entirely, but this [prevents declarative data retrieval](https://typedb.com/philosophy#why-do-we-need-a-polymorphic-database). - [ORMs work around the fundamental problem](https://typedb.com/philosophy#why-do-we-need-a-polymorphic-database) by trading off performance. ### Providing full support for polymorphism <!-- Polymorphism in programming languages and data modeling comes in the form of [interface](https://typedb.com/philosophy#what-defines-a-polymorphic-database), [inheritance](https://typedb.com/philosophy#what-defines-a-polymorphic-database), and [parametric polymorphism](https://typedb.com/philosophy#what-defines-a-polymorphic-database). --> In order to fully support polymorphism, a database needs to implement three key components: - Support for [**polymorphic** **schemas**](https://typedb.com/features#conceptual-modeling) that can express inheritance hierarchies and interface implementations. - Implementation of a fully [**variablizable** **query language**](https://typedb.com/features#polymorphic-queries) to support powerful [parametric](https://typedb.com/philosophy#what-defines-a-polymorphic-database) database operations. - Integration of an [**inference engine**](https://typedb.com/features#strong-type-system) to interpret variables in the semantic context given by the schema. ## The TypeDB database ### The schema TypeDB schemas are based on a modern type system that natively supports inheritance and interfaces, and follows a [conceptual data modeling](https://typedb.com/features#conceptual-modeling) approach, in which user-defined types subtype (based on their function) three root types: [entities](https://typedb.com/features#conceptual-modeling), [relations](https://typedb.com/features#expressive-relations), and [attributes](https://typedb.com/features#intuitive-attributes). - *Entities* are independent objects, - *Relations* depend on their *role* interfaces played by either entities or relations, - *Attributes* are properties with a value that can be *owned* by entities or relations. Interface and inheritance for these types can be combined in many ways, resulting in highly expressive ways of modeling data. ```php define full-name sub attribute, value string; id sub attribute, value string; email sub id; employee-id sub id; user sub entity, owns full-name, owns email @unique, plays mentorship:trainee; employee sub user, owns employee-id @key, plays mentorship:mentor; mentorship sub relation, relates mentor, relates trainee; ``` ### The query language The query language of TypeDB is [TypeQL](https://typedb.com/docs/typeql/overview). The syntax of TypeQL is fully variablizable and provides native support for polymorphic queries. The language is based on [fully declarative and composable](https://typedb.com/features#modern-language) patterns, mirroring the structure of natural language. ```php match $user isa user, has full-name $name, has email $email; # This returns all users of any type match $user isa employee, has full-name $name, has email $email, has employee-id $id; # This returns only users who are employees match $user-type sub user; $user isa $user-type, has full-name $name, has email $email; # This returns all users and their type ``` ### The inference engine Any query in TypeDB is [semantically validated](https://typedb.com/features#strong-type-system) by TypeDB’s inference engine for consistency with the database schema. This prevents invalid schema updates and data inserts before they can affect the integrity of the database. TypeDB can also work with data that is not physically stored in the database, but instead logically inferred based on user-specified [rules](https://typedb.com/features#symbolic-reasoning). This enables developers to cleanly separate their source data from their application logic, often allowing for complex systems to be described by combinations of simple rules. ```php define rule transitive-team-membership: when { (team: $team-1, member: $team-2) isa team-membership; (team: $team-2, member: $member) isa team-membership; } then { (team: $team-1, member: $member) isa team-membership; }; insert $john isa user, has email "john@vaticle.com"; $eng isa team, has name "Engineering "; $cloud isa team, has name "Cloud"; (team: $eng, member: $cloud) isa team-membership; (team: $cloud, member: $john) isa team-membership; match $john isa user, has email "john@vaticle.com"; (team: $team, member: $john) isa team-membership; # This will return both Cloud and Engineering for $team due to the defined rule ``` ## Effective database engineering TypeDB breaks down the patchwork of existing database paradigms into three fundamental ingredients: [types](https://typedb.com/features#strong-type-system), [inheritance](https://typedb.com/features#conceptual-modeling), and [interfaces](https://typedb.com/features#polymorphic-queries). This provides a unified way of working with data across all database applications, that directly impacts development: - Make use of full [object model parity](https://typedb.com/#solve-object-relational-mismatch-entirely-within-the-database) when working with OOP - Ensure [continuous extensibility](https://typedb.com/features#conceptual-modeling) of your data model - Work with high-level [logical abstractions](https://typedb.com/features#conceptual-modeling) eliminating the need for physical data modeling - Let TypeDB's inference engine guarantee [data-consistency](https://typedb.com/#avoid-data-redundancy-and-ensure-data-consistency-in-real-time) at all times - Write high-clarity code with TypeQL's [near-natural](https://typedb.com/features#modern-language) queries even for the most complex databases - Unleash the power of [fully declarative and composable](https://typedb.com/features#modern-language) patterns onto your data ## Installation and editions ### TypeDB editions * [TypeDB Cloud](https://cloud.typedb.com) — multi-cloud DBaaS * [TypeDB Cloud self-hosted](mailto://sales@vaticle.com) — allows you to deploy TypeDB Cloud in your own environment * **TypeDB Core** — Open-source edition of TypeDB ← _This repository_ For a comparison of all three editions, see the [Deploy](https://typedb.com/deploy) page on our website. ### Download and run TypeDB Core You can download TypeDB from the [GitHub Releases](https://github.com/vaticle/typedb/releases).

### 常规Java工具，算法，加密，数据库，面试题，源代码分析，解决方案 <br> 有家杂志曾对全国60岁以上的老人进行了这样一次问卷调查:你最后悔什么? 列出10项人们生活中容易后悔的事情，供被调查者选择，回收有效问卷并进行统计分析后，竟得出了这样的结果。 **第一名:年轻时不够努力，导致一事无成(75%)**  所谓少壮不努力，老大徒伤悲。青春岁月里，又常常碰到那么多的诱惑甚至陷阱，当你猛然醒悟时，也许白发早生，竟然一事无成。 趁着你还有时间、有精力、有体力，赶快制定一个切实可行的计划，然后开始百折不挠一路向前，老来回忆，少些遗憾。 **第二名:年轻的时候选错了职业(70%)**  三个大学生被同时分配到某机关工作，一年后，其中一个由于不甘心整天看主管脸色，跳槽到另一家企业去了，另外两位依旧安稳地过着朝九晚五的日子。又一年后，另外一个学生决定辞职下海，剩下那个依然没有动心。 若干年后，三人相聚，到企业去的那位同学成了高管，下海的那位成了千万富翁，而留在机关的那位却依旧在领导的呵斥声中消磨着自己所剩无几的“大好时光”。 许多人在选择职业时考虑的第一因素就是稳定的收入和安稳舒适的生活，而不太愿意去面对那些具有挑战性的机会。没有了压力，自然就缺乏了动力，没有了动力，也就埋没了潜力。 **第三名:对子女教育不当(62%)**  孩子是自己生命、希望的延续，许多人为了孩子可以倾尽所有，但望子成龙、盼女成凤可能只是父母单方面的良好愿望。对于儿女而言，他们也许只是想做一个简单快乐的平凡人。 许多父母采取了强制、监督甚至棍棒等方式来逼迫孩子按照自己设计的线路发展。可到最后，多数父母却不得不在对现实感到失望，只有极少数所谓的“成功者”例外。他们也不由地感叹孩子这些年过得太苦，没有享受到应有的快乐与阳光。 **第四名:没好好珍惜自己的伴侣(57%)**  醉过方知酒浓，爱过方知情重。感情，总是拥有时不懂得珍惜，失去后才知道珍贵。人类永远发明不出的两种物质，一是忘情水，二是后悔药。年轻的时候不去珍惜、体谅和理解，待到年老时，后悔已经来不及。 **第五名:没有善待自己的身体(49%)**  “身体是革命的本钱”，这句话永远都不会过时，许多人在60岁前用身体去换取一切，在60岁以后又用一切去换取身体的健康。 世界上没有什么东西比自己的健康更加重要，没有一个好的身体，纵有千万家产又如何?

Pcap4J wraps a native packet capture library ([libpcap](http://www.tcpdump.org/), [WinPcap](http://www.winpcap.org/), or [Npcap](https://github.com/nmap/npcap)) via [JNA](https://github.com/twall/jna) and provides you Java-Oriented APIs.

Although there are some implementations of the pcap such as libpcap (for UNIX) and WinPcap (for Windows), because they are both native libraries, a Java wrapper library was necessary in order to use them for SNeO. I researched it and found three Java wrapper libraries for pcap: [jpcap](http://jpcap.sourceforge.net/), [jNetPcap](http://jnetpcap.com/), and [Jpcap](http://netresearch.ics.uci.edu/kfujii/Jpcap/doc/). But both jpcap and jNetPcap were unsuitable for SNeO because they seemed to be designed for mainly capturing packets and not to be useful for making and sending packets so much. On the other hand, Jpcap looked useful for making and sending packets. But it had a defect in capturing ICMP packets and its development seemed to be stopped long ago. That's why I started developing Pcap4j. Features -------- * Capturing packets via a network interface and converting them into Java objects. You can get/set each field of a packet header via the Java object converted from the packet. You can also craft a packet object from scratch. * Sending packet objects to a real network. * Supported protocols: * Ethernet, Linux SLL, raw IP, PPP (RFC1661, RFC1662), BSD (Mac OS X) loopback encapsulation, and Radiotap * IEEE 802.11 * Probe Request * LLC and SNAP * IEEE802.1Q * ARP * IPv4 (RFC791 and RFC1349) and IPv6 (RFC2460) * ICMPv4 (RFC792) and ICMPv6 (RFC4443, RFC4861, and RFC6275) * TCP (RFC793, RFC2018, and draft-ietf-tcpm-1323bis-21), UDP, and SCTP (only common header) * GTPv1 (only GTP-U and GTP-C header) * DNS (RFC1035, RFC3596, and RFC6844) * All built-in packet classes are serializable and thread-safe (practically immutable). * You can add a protocol support without modifying Pcap4J library itself. * Dumping and reading pcap-formatted files (e.g. a capture file of Wireshark). How to use ---------- #### System requirements #### ##### Dependencies ##### Pcap4j 1.1.0 or older needs Java 5.0+. Pcap4j 1.2.0 or newer needs Java 6.0+. And also a pcap native library (libpcap 1.0.0+, WinPcap 3.0+, or Npcap), jna, slf4j-api, and an implementation of logger for slf4j are required. I'm using the following libraries for the test. * libpcap 1.1.1 * WinPcap 4.1.2 * jna 5.1.0 * slf4j-api 1.7.25 * logback-core 1.0.0 * logback-classic 1.0.0 ##### Platforms ##### I tested Pcap4j on the following OSes with x86 or x64 processors. * Windows: XP, Vista, 7, [10](http://tbd.kaitoy.xyz/2016/01/12/pcap4j-with-four-native-libraries-on-windows10/), 2003 R2, 2008, 2008 R2, and 2012 * Linux * RHEL: 5, 6, and 7 * CentOS: 5, 6, and 7 * Ubuntu: 13 * UNIX * Solaris: 10 * FreeBSD: 10 And tomute tested Pcap4j on Mac OS X. The report is [here](http://tomute.hateblo.jp/entry/2013/01/27/003209). Thank you, tomute! I hope Pcap4j can run on the other OSes supported by both JNA and libpcap. ##### Others ##### Pcap4J needs administrator/root privileges. Or, if on Linux, you can run Pcap4J with a non-root user by granting capabilities `CAP_NET_RAW` and `CAP_NET_ADMIN` to your java command by the following command: `setcap cap_net_raw,cap_net_admin=eip /path/to/java` #### Documents #### The latest JavaDoc is [here](https://www.javadoc.io/doc/org.pcap4j/pcap4j-distribution/1.8.2). Each version's JavaDoc is on the [Maven Central Repository](http://search.maven.org/#search|ga|1|g%3A%22org.pcap4j%22). Refer to [here](https://github.com/kaitoy/pcap4j/blob/v1/www/pcap4j_modules.md) for information about Pcap4J modules. Because Pcap4J is a wrapper of a pcap native library, the following documents help you to understand how to use Pcap4J. * [Programming with pcap](http://www.tcpdump.org/pcap.html) * [WinPcap Manuals](http://www.winpcap.org/docs/default.htm) * [Mapping between pcap API and Pcap4J API](https://github.com/kaitoy/pcap4j/blob/v1/www/api_mappings.md) You can learn how to write Pcap4J programs from [samples](https://github.com/kaitoy/pcap4j/tree/v1/pcap4j-sample/src/main/java/org/pcap4j/sample). Learn more about Pcap4j from the following documents: * [Learn about packet class](https://github.com/kaitoy/pcap4j/blob/v1/www/Packet.md) * [Learn about Packet Factory](https://github.com/kaitoy/pcap4j/blob/v1/www/PacketFactory.md) * [How to add protocol support](https://github.com/kaitoy/pcap4j/blob/v1/www/HowToAddProtocolSupport.md) * [kaitoy's blog](http://tbd.kaitoy.xyz/tags/pcap4j/) #### How to run samples #### See the following examples: * [org.pcap4j.sample.Loop](https://github.com/kaitoy/pcap4j/blob/v1/www/sample_Loop.md) * [org.pcap4j.sample.SendArpRequest](https://github.com/kaitoy/pcap4j/blob/v1/www/sample_SendArpRequest.md) If you want to run a sample in pcap4j-sample on Eclipse, add pcap4j-packetfactory-static or pcap4j-packetfactory-propertiesbased project to the top of User Entries in Classpath tab of the Run Configuration for the sample. #### How to use in Maven project #### Add a dependency to the pom.xml as like below: ```xml <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> ... <dependencies> <dependency> <groupId>org.pcap4j</groupId> <artifactId>pcap4j-core</artifactId> <version>1.8.2</version> </dependency> <dependency> <groupId>org.pcap4j</groupId> <artifactId>pcap4j-packetfactory-static</artifactId> <version>1.8.2</version> </dependency> ... </dependencies> ... </project> ``` #### About native library loading #### By default, Pcap4j loads the native libraries on the following conditions: * Windows * search path: The paths in the `PATH` environment variable, etc. (See [MSDN](https://msdn.microsoft.com/en-us/library/7d83bc18.aspx) for the details.) * file name: wpcap.dll and Packet.dll * Linux/UNIX * search path: The search paths of shared libraries configured on the OS. (e.g. The paths in the `LD_LIBRARY_PATH` environment variable) * file name: libpcap.so * Mac OS X * search path: The search paths of shared libraries configured on the OS. (e.g. The paths in the `DYLD_LIBRARY_PATH` environment variable) * file name: libpcap.dylib You can use the following Java system properties to change the default behavior. * jna.library.path: The search path * org.pcap4j.core.pcapLibName: The full path of the pcap library (wpcap.dll, libpcap.so, or libpcap.dylib) * (Windows only) org.pcap4j.core.packetLibName: The full path of the packet library (Packet.dll) ##### WinPcap or Npcap ##### There are two native pcap libraries for Windows; WinPcap and Npcap. The development of WinPcap has stopped since version 4.1.3 (libpcap 1.0.0 base) was released on 3/8/2013, while Npcap is still being developed. So, you should pick Npcap if you want to use new features or so. Pcap4J can load WinPcap without tricks because it's installed in `%SystemRoot%\System32\`. On the other hand, because Npcap is installed in `%SystemRoot%\System32\Npcap\` by default, you need to do either of the following so that Pcap4J can load it: * Add `%SystemRoot%\System32\Npcap\` to `PATH`. * Set `jna.library.path` to `%SystemRoot%\System32\Npcap\`. * Set `org.pcap4j.core.pcapLibName` to `%SystemRoot%\System32\Npcap\wpcap.dll` and `org.pcap4j.core.packetLibName` to `%SystemRoot%\System32\Npcap\Packet.dll`. * Install Npcap with `WinPcap Compatible Mode` on. ### Docker ### [](https://microbadger.com/images/kaitoy/pcap4j) A Docker image for Pcap4J on CentOS is available at [Docker Hub](https://registry.hub.docker.com/u/kaitoy/pcap4j/). Download it by `docker pull kaitoy/pcap4j` and execute `docker run kaitoy/pcap4j:latest` to start capturing packets from eth0 on the container. This image is built everytime a commit is made on the Git repositry. How to build ------------ 1. Install libpcap, WinPcap, or Npcap: Install WinPcap (if Windows) or libpcap (if Linux/UNIX). It's needed for the unit tests which are run during a build. 2. Install JDK: Download and install JDK 9, 10, or 11, and set the environment variable ***JAVA_HOME*** properly. 3. Add the JDK to [Maven toolchains](https://maven.apache.org/guides/mini/guide-using-toolchains.html): Create [toolchains.xml](https://maven.apache.org/ref/3.6.1/maven-core/toolchains.html) describing the JDK installed at the previous step and put it into `~/.m2/`. `toolchains.xml` is like below: ```xml <?xml version="1.0" encoding="UTF-8"?> <toolchains xmlns="http://maven.apache.org/TOOLCHAINS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/TOOLCHAINS/1.1.0 http://maven.apache.org/xsd/toolchains-1.1.0.xsd"> <toolchain> <type>jdk</type> <provides> <version>11</version> </provides> <configuration> <jdkHome>/path/to/jdk-11</jdkHome> </configuration> </toolchain> </toolchains> ``` 4.

# ZXingLite  [](https://raw.githubusercontent.com/jenly1314/ZXingLite/master/app/release/app-release.apk) [](https://repo1.maven.org/maven2/com/github/jenly1314/zxing-lite) [](https://bintray.com/beta/#/jenly/maven/zxing-lite) [](https://jitpack.io/#jenly1314/ZXingLite) [](https://travis-ci.org/jenly1314/ZXingLite) [](https://circleci.com/gh/jenly1314/ZXingLite) [](https://android-arsenal.com/api?level=21) [](http://www.apache.org/licenses/LICENSE-2.0) ZXingLite for Android 是ZXing的精简极速版，基于ZXing库优化扫码和生成二维码/条形码功能，扫码界面完全支持自定义；使用ZXingLite可快速实现扫码识别相关功能。 > 简单如斯，你不试试？ ## Gif 展示  > 你也可以直接下载 [演示App](https://raw.githubusercontent.com/jenly1314/ZXingLite/master/app/release/app-release.apk) 体验效果 ## 引入 ### Gradle: 1. 在Project的 **build.gradle** 或 **setting.gradle** 中添加远程仓库 ```gradle repositories { //... mavenCentral() } ``` 2. 在Module的 **build.gradle** 里面添加引入依赖项 ```gradle // AndroidX 版本 implementation 'com.github.jenly1314:zxing-lite:3.1.0' ``` ### 温馨提示 #### 关于ZXingLite版本与编译的SDK版本要求 > 使用 **v3.1.x** 以上版本时，要求 **compileSdkVersion >= 34** > 使用 **v3.0.x** 以上版本时，要求 **compileSdkVersion >= 33** > 如果 **compileSdkVersion < 33** 请使用 [**v2.x版本**](https://github.com/jenly1314/ZXingLite/tree/2.x/) ## 使用 ### 版本变化说明 #### 3.x版本的变化 从 **2.x** 到 **3.x** 主要变化如下： * 2.x版本中的 **CameraScan** 相关核心类被移除了； > 从3.0.0版本开始改为依赖 [CameraScan](https://github.com/jenly1314/CameraScan)；（[CameraScan](https://github.com/jenly1314/CameraScan)是一个独立的库，单独进行维护） * 2.x版本中的 **ViewfinderView** 被移除了； > 从3.0.0版本开始改为依赖 [ViewfinderView](https://github.com/jenly1314/ViewfinderView)；（[ViewfinderView](https://github.com/jenly1314/ViewfinderView)是一个独立的库，单独进行维护） * 2.x版本中的 **CaptureActivity** 和 **CaptureFragment** 相关基类被移除了； > 从3.0.0版本开始改为 **BarcodeCameraActivity** 和 **BarcodeCameraFragment** 除了以上几点主要差异变化，3.x版本的整体使用方式和2.x基本类似；3.x版本在2.x版本的基础上再次进行重构，将 **CameraScan** 相关的公共基础类从 **ZXingLite** 中移除后，维护起来更方便了。 > 如果你是从 **2.x** 版本升级至 **3.x** 版本，那么你需要知道上面所说的主要差异；特别是独立出去单独维护的库，其包名都有所变化，这一点需要特别注意；请谨慎升级。 > 如果你使用的是2.x版本的话请直接[查看v2.x分支版本](https://github.com/jenly1314/ZXingLite/tree/2.x/) #### 3.x版本的使用 3.x的实现主要是以 [CameraScan](https://github.com/jenly1314/CameraScan)作为基础库去实现具体的分析检测功能，所以你可以先去看下 [CameraScan](https://github.com/jenly1314/CameraScan)的使用说明；在了解了 [CameraScan](https://github.com/jenly1314/CameraScan)的基本使用方式后，然后再结合当前的使用说明就可以轻松的集成并使用 **ZXingLite**了。 ### 主要类说明 #### 关于Analyzer的实现类 内部提供了Analyzer对应的实现，都是为快速实现扫码识别而提供的分析器。 内部提供的分析器有多个；一般情况下，你只需要知道最终实现的 [**MultiFormatAnalyzer**](zxing-lite/src/main/java/com/king/zxing/analyze/MultiFormatAnalyzer.java) 和 [**QRCodeAnalyzer**](zxing-lite/src/main/java/com/king/zxing/analyze/QRCodeAnalyzer.java) 即可： **MultiFormatAnalyzer** 和 **QRCodeAnalyzer** 的主要区别，从名字大概就能看的出来；一个是可识别多种格式，一个是只识别二维码（具体需要支持识别哪些格式的条码，其实还要看提供的**DecodeConfig**是怎么配置的）。 > 本可以不需要 ****QRCodeAnalyzer****，之所以提供一个 **QRCodeAnalyzer** 是因为有很多需求是只需要识别二维码就行；如果你有连续扫码的需求或不知道怎么选时，推荐直接选择 **MultiFormatAnalyzer** 。 #### 关于DecodeConfig DecodeConfig：解码配置；主要用于在扫码识别时，提供一些配置，便于扩展。通过配置可决定内置分析器的能力，从而间接的控制并简化扫码识别的流程。一般在使用 **Analyzer** 的实现类时，你可能会用到。 #### 关于DecodeFormatManager DecodeConfig：解码格式管理器；主要将多种条码格式进行划分与归类，便于提供快捷配置。 #### 关于CodeUtils 工具类 **CodeUtils** 中主要提供；解析条形码/二维码、生成条形码/二维码相关的能力。 CodeUtils的使用示例 ```Java // 生成二维码 CodeUtils.createQRCode(content,600,logo); // 生成条形码 CodeUtils.createBarCode(content, BarcodeFormat.CODE_128,800,200); // 解析条形码/二维码 CodeUtils.parseCode(bitmap); // 解析二维码 CodeUtils.parseQRCode(bitmap); ``` #### 关于BarcodeCameraScanActivity 通过继承BarcodeCameraScanActivity实现扫二维码完整示例 ```java public class QRCodeScanActivity extends BarcodeCameraScanActivity { @Override public void initCameraScan(@NonNull CameraScan<Result> cameraScan) { super.initCameraScan(cameraScan); // 根据需要设置CameraScan相关配置 cameraScan.setPlayBeep(true); } @Nullable @Override public Analyzer<Result> createAnalyzer() { // 初始化解码配置 DecodeConfig decodeConfig = new DecodeConfig(); decodeConfig.setHints(DecodeFormatManager.QR_CODE_HINTS)//如果只有识别二维码的需求，这样设置效率会更高，不设置默认为DecodeFormatManager.DEFAULT_HINTS .setFullAreaScan(false)//设置是否全区域识别，默认false .setAreaRectRatio(0.8f)//设置识别区域比例，默认0.8，设置的比例最终会在预览区域裁剪基于此比例的一个矩形进行扫码识别 .setAreaRectVerticalOffset(0)//设置识别区域垂直方向偏移量，默认为0，为0表示居中，可以为负数 .setAreaRectHorizontalOffset(0);//设置识别区域水平方向偏移量，默认为0，为0表示居中，可以为负数 // BarcodeCameraScanActivity默认使用的MultiFormatAnalyzer，这里可以改为使用QRCodeAnalyzer return new QRCodeAnalyzer(decodeConfig); } /** * 布局ID；通过覆写此方法可以自定义布局 * * @return 布局ID */ @Override public int getLayoutId() { return R.layout.activity_qrcode_scan; } @Override public void onScanResultCallback(@NonNull AnalyzeResult<Result> result) { // 停止分析 getCameraScan().setAnalyzeImage(false); // 返回结果 Intent intent = new Intent(); intent.putExtra(CameraScan.SCAN_RESULT, result.getResult().getText()); setResult(Activity.RESULT_OK, intent); finish(); } } ``` > **BarcodeCameraScanFragment** 的使用方式与之类似。 更多使用详情，请查看[app](app)中的源码使用示例或直接查看[API帮助文档](https://jitpack.io/com/github/jenly1314/ZXingLite/latest/javadoc/) ### 其他 #### JDK版本与API脱糖 当使用ZXingLite为 **v2.3.x** 以上版本时，（即：更新zxing至v3.5.1后）；如果要兼容Android 7.0 (N) 以下版本（即：minSdk<24），可通过脱糖获得 Java 8 及更高版本 API。 ```gradle compileOptions { // Flag to enable support for the new language APIs coreLibraryDesugaringEnabled true // Sets Java compatibility to Java 11 targetCompatibility JavaVersion.VERSION_11 sourceCompatibility JavaVersion.VERSION_11 } ``` ```gradle dependencies { coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.2.3' } ``` ## 相关推荐 #### [MLKit](https://github.com/jenly1314/MLKit) 一个强大易用的工具包。通过ML Kit您可以很轻松的实现文字识别、条码识别、图像标记、人脸检测、对象检测等功能。 #### [WeChatQRCode](https://github.com/jenly1314/WeChatQRCode) 基于OpenCV开源的微信二维码引擎移植的扫码识别库。 #### [CameraScan](https://github.com/jenly1314/CameraScan) 一个简化扫描识别流程的通用基础库。 #### [ViewfinderView](https://github.com/jenly1314/ViewfinderView) ViewfinderView一个取景视图：主要用于渲染扫描相关的动画效果。 ## 版本记录 #### v3.1.0：2023-12-31 * 更新CameraScan至v1.1.0 * 更新zxing至v3.5.2 * 更新compileSdkVersion至34 * 更新Gradle至v8.0 #### v3.0.1：2023-9-13 * 更新CameraScan至v1.0.1 * 更新ViewfinderView至v1.1.0 #### v3.0.0：2023-8-23 * 将通用基础类拆分移除并进行重构，后续维护更便捷 * 移除 **CameraScan** 相关核心类，改为依赖 [CameraScan](https://github.com/jenly1314/CameraScan) * 移除扫码取景视图 **ViewfinderView**，改为依赖 [ViewfinderView](https://github.com/jenly1314/ViewfinderView) * 移除 **CaptureActivity** 和 **CaptureFragment**，新增 **BarcodeCameraScanActivity** 和 **BarcodeCameraScanFragment** 来替代 * 优化扫描分析过程的性能体验（优化帧数据分析过程） #### v2.4.0：2023-4-15 * 优化CameraScan的缺省配置（CameraConfig相关配置） * 优化ViewfinderView自定义属性（新增laserDrawableRatio） * 优化ImageAnalyzer中YUV数据的处理 * 更新CameraX至v1.2.2 #### v2.3.1：2023-3-4 * 更新CameraX至v1.2.1 * 更新Gradle至v7.5 * 优化细节 #### v2.3.0：2022-12-11 * 更新CameraX至v1.2.0 * 更新zxing至v3.5.1 * 更新compileSdkVersion至33 #### [查看更多版本记录](change_log.md) ## 赞赏 如果您喜欢ZXingLite，或感觉ZXingLite帮助到了您，可以点右上角“Star”支持一下，您的支持就是我的动力，谢谢 :smiley: <p>您也可以扫描下面的二维码，请作者喝杯咖啡 :coffee: <div> <img src="https://jenly1314.github.io/image/page/rewardcode.png"> </div> ## 关于我 | 我的博客 | GitHub | Gitee | CSDN | 博客园 | |:------------------------------------------------------------------------------------|:----------------------------------------------------------------------------------------|:---------------------------------------------------------------------------------------|:-------------------------------------------------------------------------------------|:-------------------------------------------------------------------------------| | <a title="我的博客" href="https://jenly1314.github.io" target="_blank">Jenly's Blog</a> | <a title="GitHub开源项目" href="https://github.com/jenly1314" target="_blank">jenly1314</a> | <a title="Gitee开源项目" href="https://gitee.com/jenly1314" target="_blank">jenly1314</a> | <a title="CSDN博客" href="http://blog.csdn.net/jenly121" target="_blank">jenly121</a> | <a title="博客园" href="https://www.cnblogs.com/jenly" target="_blank">jenly</a> | ## 联系我 | 微信公众号 | Gmail邮箱 | QQ邮箱 | QQ群 | QQ群 | |:-------------|:---------------------------------------------------------------------------------|:----------------------------------------------------------------------------------|:--------------------------------------------------------------------------------------------------------------------------|:--------------------------------------------------------------------------------------------------------------------------| | [Jenly666](http://weixin.qq.com/r/wzpWTuPEQL4-ract92-R) | <a title="给我发邮件" href="mailto:jenly1314@gmail.com" target="_blank">jenly1314</a> | <a title="给我发邮件" href="mailto:jenly1314@vip.qq.com" target="_blank">jenly1314</a> | <a title="点击加入QQ群" href="https://qm.qq.com/cgi-bin/qm/qr?k=6_RukjAhwjAdDHEk2G7nph-o8fBFFzZz" target="_blank">20867961</a> | <a title="点击加入QQ群" href="https://qm.qq.com/cgi-bin/qm/qr?k=Z9pobM8bzAW7tM_8xC31W8IcbIl0A-zT" target="_blank">64020761</a> | <div> <img src="https://jenly1314.github.io/image/page/footer.png"> </div>

spring-projects/spring-integration

Spring Integration provides an extension of the Spring programming model to support the well-known Enterprise Integration Patterns (EIP)

eip java microservices spring

<img align="right" width="250" height="250" src="https://spring.io/img/projects/spring-integration.svg?v=2"> # Spring Integration [](https://github.com/spring-projects/spring-integration/actions/workflows/ci-snapshot.yml) [](https://ge.spring.io/scans?search.rootProjectNames=spring-integration) Extends the Spring programming model to support the well-known Enterprise Integration Patterns. Spring Integration enables lightweight messaging within Spring-based applications and supports integration with external systems via declarative adapters. Those adapters provide a higher-level of abstraction over Spring’s support for remoting, messaging, and scheduling. Spring Integration’s primary goal is to provide a simple model for building enterprise integration solutions while maintaining the separation of concerns that is essential for producing maintainable, testable code. Using the Spring Framework encourages developers to code using interfaces and use dependency injection (DI) to provide a Plain Old Java Object (POJO) with the dependencies it needs to perform its tasks. Spring Integration takes this concept one step further, where POJOs are wired together using a messaging paradigm and individual components may not be aware of other components in the application. Such an application is built by assembling fine-grained reusable components to form a higher level of functionality. With careful design, these flows can be modularized and also reused at an even higher level. In addition to wiring together fine-grained components, Spring Integration provides a wide selection of channel adapters and gateways to communicate with external systems. Channel Adapters are used for one-way integration (send or receive); gateways are used for request/reply scenarios (inbound or outbound). # Installation and Getting Started First, you need dependencies in your POM/Gradle: ```xml <dependency> <groupId>org.springframework.integration</groupId> <artifactId>spring-integration-core</artifactId> </dependency> ``` which is also pulled transitively if you deal with target protocol channel adapters. For example for Apache Kafka support you need just this: ```xml <dependency> <groupId>org.springframework.integration</groupId> <artifactId>spring-integration-kafka</artifactId> </dependency> ``` For annotations or Java DSL configuration you need to *enable* Spring Integration in the application context: ```java @EnableIntegration @Configuration public class ExampleConfiguration { } ``` # Code of Conduct Please see our [Code of conduct](https://github.com/spring-projects/.github/blob/main/CODE_OF_CONDUCT.md). # Reporting Security Vulnerabilities Please see our [Security policy](https://github.com/spring-projects/spring-integration/security/policy). # Documentation The Spring Integration maintains reference documentation ([published](https://docs.spring.io/spring-integration/reference/) and [source](src/reference/antora)), GitHub [wiki pages](https://github.com/spring-projects/spring-integration/wiki), and an [API reference](https://docs.spring.io/spring-integration/docs/current/api/). There are also [guides and tutorials](https://spring.io/guides) across Spring projects. # Checking out and Building To check out the project and build from the source, do the following: git clone git://github.com/spring-projects/spring-integration.git cd spring-integration ./gradlew clean test or ./gradlew clean testAll The latter runs additional tests (those annotated with `@LongRunningIntegrationTest`); it is a more thorough test but takes quite a lot longer to run. The test results are captured in `build/reports/tests/test` (or `.../testAll`) under each module (in HTML format). Add `--continue` to the command to perform a complete build, even if there are failing tests in some modules; otherwise the build will stop after the current module(s) being built are completed. **NOTE:** While Spring Integration runs with Java SE 17 or higher, a Java 17 compiler is required to build the project. To build and install jars into your local Maven cache: ./gradlew build publishToMavenLocal To build api Javadoc (results will be in `build/api`): ./gradlew api To build the reference documentation (results will be in `build/site`): ./gradlew antora To build complete distribution including `-dist`, `-docs`, and `-schema` zip files (results will be in `build/distributions`): ./gradlew dist # Using Eclipse or Spring Tool Suite (with BuildShip Plugin) If you have the BuildShip plugin installed, *File -> Import -> Gradle -> Existing Gradle Project* # Using Eclipse or Spring Tool Suite (when the BuildShip Plugin is not installed) To generate Eclipse metadata (.classpath and .project files, etc.), do the following: ./gradlew eclipse Once complete, you may then import the projects into Eclipse as usual: *File -> Import -> General -> Existing projects into workspace* Browse to the *'spring-integration'* root directory. All projects should import free of errors. # Using IntelliJ IDEA To import the project into IntelliJ IDEA: File -> Open... -> and select build.gradle from spring-integration project root directory # Guidelines See also [Contributor Guidelines](https://github.com/spring-projects/spring-integration/blob/main/CONTRIBUTING.adoc). # Resources For more information, please visit the Spring Integration website at: [https://spring.io/projects/spring-integration](https://spring.io/projects/spring-integration/)

PaperMC/Velocity

The modern, next-generation Minecraft server proxy.

forge java minecraft minecraft-forge minecraft-server-proxy server-proxy velocity

# Velocity [](https://papermc.io/downloads/velocity) [](https://discord.gg/papermc) A Minecraft server proxy with unparalleled server support, scalability, and flexibility. Velocity is licensed under the GPLv3 license. ## Goals * A codebase that is easy to dive into and consistently follows best practices for Java projects as much as reasonably possible. * High performance: handle thousands of players on one proxy. * A new, refreshing API built from the ground up to be flexible and powerful whilst avoiding design mistakes and suboptimal designs from other proxies. * First-class support for Paper, Sponge, Fabric and Forge. (Other implementations may work, but we make every endeavor to support these server implementations specifically.) ## Building Velocity is built with [Gradle](https://gradle.org). We recommend using the wrapper script (`./gradlew`) as our CI builds using it. It is sufficient to run `./gradlew build` to run the full build cycle. ## Running Once you've built Velocity, you can copy and run the `-all` JAR from `proxy/build/libs`. Velocity will generate a default configuration file and you can configure it from there. Alternatively, you can get the proxy JAR from the [downloads](https://papermc.io/downloads/velocity) page.

jline/jline3

JLine is a Java library for handling console input.

<!-- Copyright (c) 2002-2020, the original author or authors. This software is distributable under the BSD license. See the terms of the BSD license in the documentation provided with this software. https://opensource.org/licenses/BSD-3-Clause --> # JLine [](https://opensource.org/licenses/BSD-3-Clause) [](https://maven-badges.herokuapp.com/maven-central/org.jline/jline) [](https://travis-ci.org/jline/jline3) [](https://ci.appveyor.com/project/gnodet/jline3) JLine is a Java library for handling console input. It is similar in functionality to [BSD editline](http://www.thrysoee.dk/editline/) and [GNU readline](http://www.gnu.org/s/readline/) but with additional features that bring it in par with [ZSH line editor](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html). People familiar with the readline/editline capabilities for modern shells (such as bash and tcsh) will find most of the command editing features of JLine to be familiar. JLine 3.x is an evolution of [JLine 2.x](https://github.com/jline/jline2). # License JLine is distributed under the [BSD License](https://opensource.org/licenses/BSD-3-Clause), meaning that you are completely free to redistribute, modify, or sell it with almost no restrictions. # Documentation * [demos](https://github.com/jline/jline3/wiki/Demos) * [wiki](https://github.com/jline/jline3/wiki) * [javadoc](https://www.javadoc.io/doc/org.jline/jline/) # Forums * [jline-users](https://groups.google.com/group/jline-users) * [jline-dev](https://groups.google.com/group/jline-dev) # Artifacts JLine can be used with a single bundle or smaller fine grained jars. The bundle contains all jars except `jline-groovy` that must be included in classpath if you want to use scripting capabilities. The big bundle is named: jline-${jline.version}.jar The dependencies are minimal: you may use JLine without any dependency on *nix systems, but in order to support windows or more advanced usage, you will need to add either [`Jansi`](https://repo1.maven.org/maven2/org/fusesource/jansi/jansi/1.18/jansi-1.18.jar) or [`JNA`](https://repo1.maven.org/maven2/net/java/dev/jna/jna/5.3.1/jna-5.3.1.jar) library. You can also use fine grained jars: * `jline-terminal`: the `Terminal` api and implementations * `jline-terminal-jansi`: terminal implementations leveraging the `Jansi` library * `jline-terminal-jni`: terminal implementations leveraging the JNI native library * `jline-terminal-jna`: terminal implementations leveraging the `JNA` library * `jline-terminal-ffm`: terminal implementations leveraging the Foreign Functions & Mapping layer * `jline-native`: the native library * `jline-reader`: the line reader (including completion, history, etc...) * `jline-style`: styling api * `jline-remote-ssh`: helpers for using jline with [Mina SSHD](http://mina.apache.org/sshd-project/) * `jline-remote-telnet`: helpers for using jline over telnet (including a telnet server implementation) * `jline-builtins`: several high level tools: `less` pager, `nano` editor, `screen` multiplexer, etc... * `jline-console`: command registry, object printer and widget implementations * `jline-groovy`: `ScriptEngine` implementation using Groovy ## Supported platforms JLine supports the following platforms: * FreeBSD * Linux * OS X * Solaris * Windows ## FFM vs JNI vs Jansi vs JNA vs Exec To perform the required operations, JLine needs to interoperate with the OS layer. This is done through the JLine `TerminalProvider` interface. The terminal builder will automatically select a provider amongst the ones that are available. On the Windows platform, relying on native calls is mandatory, so you need to have a real provider (`jline-terminal-xxx` jar) registered and its dependencies available (usually the Jansi or JNA library). Failing to do so will create a `dumb` terminal with no advanced capabilities. By default, the following order will be used. ### FFM The [FFM](https://docs.oracle.com/en/java/javase/21/core/foreign-function-and-memory-api.html#GUID-FBE990DA-C356-46E8-9109-C75567849BA8) provider is available since JLine 3.24 and when running on JDK >= 21. It's very lightweight with no additional dependencies. With JLine 3.26, the FFM provider requires JDK 22 with the `--enable-native-access=ALL-UNNAMED` JVM option. Note that JLine 3.24 and 3.25 uses the preview version of FFM support shipped in JDK 21 which is incompatible with the final version in JDK 22. ### JNI Since JLine 3.24.0, JLine provides its own JNI based provider and native libraries. This is the best default choice, with no additional dependency, but it requires loading a native library. ### JANSI The [Jansi](https://github.com/fusesource/jansi) library is a library specialized in supporting ANSI sequences in terminals. Historically, the JNI methods used by JLine were provided by Jansi. In order to minimize the maintenance cost, Jansi will be merged into JLine 3.25. This provider has been deprecated in 3.26 in favor of the JNI provider. ### JNA The [JNA](https://github.com/java-native-access/jna) library aims to provide an alternative way to access native methods without requiring writing a full JNI native library. If JNA is in JLine's class loader, the provider may be used. JNA is not supported on Apple M2 architectures. This provider has been deprecated in 3.26 in favor of the FFM provider. ### Exec The exec provider is available on Posix systems and on Windows when running under [Cygwin](https://www.cygwin.com) or [MSys2](https://www.msys2.org). This provider launches child processes whenever the terminal is accessed (using `Terminal.getAttributes`, `Terminal.setAttributes`, `Terminal.getSize`, `Terminal.setSize`). This provider also does not support external terminals (for example when creating a terminal for an incoming connection) and does not support the Windows native environment. # Maven Usage Use the following definition to use JLine in your maven project: ```xml <dependency> <groupId>org.jline</groupId> <artifactId>jline</artifactId> <version>${jline.version}</version> </dependency> ``` JLine can also be used with more low-level jars: ```xml <dependency> <groupId>org.jline</groupId> <artifactId>jline-terminal</artifactId> <version>${jline.version}</version> </dependency> <dependency> <groupId>org.jline</groupId> <artifactId>jline-reader</artifactId> <version>${jline.version}</version> </dependency> ``` All the jars and releases are available from Maven Central, so you'll find everything at the following location <https://repo1.maven.org/maven2/org/jline/>. # Building ## Requirements * Maven 3.5.4+ * Java 8+ at runtime * Java 21+ at build time * Graal 23.1+ (native-image) Check out and build: ```sh git clone git://github.com/jline/jline3.git cd jline3 ./build rebuild ``` Build Graal native-image demo: ```sh ./build rebuild -Pnative-image ``` ## Results The following artifacts are build: The big bundle includes everything (except `jline-groovy`) and is located at: jline/target/jline-${jline.version}.jar The fine grained bundles are located at: terminal/target/jline-terminal-${jline.version}.jar terminal-jansi/target/jline-jansi-${jline.version}.jar terminal-jna/target/jline-jna-${jline.version}.jar reader/target/jline-reader-${jline.version}.jar style/target/jline-style-${jline.version}.jar remote-telnet/target/jline-remote-telnet-${jline.version}.jar remote-ssh/target/jline-remote-ssh-${jline.version}.jar builtins/target/jline-builtins-${jline.version}.jar console/target/jline-console-${jline.version}.jar groovy/target/jline-groovy-${jline.version}.jar Maven has a concept of `SNAPSHOT`. During development, the jline version will always ends with `-SNAPSHOT`, which means that the version is in development and not a release. Note that all those artifacts are also installed in the local maven repository, so you will usually find them in the following folder: `~/.m2/repository/org/jline/`. ## Running the demo To run the demo, simply use one of the following commands after having build `JLine` ```sh # Gogo terminal ./build demo # Groovy REPL ./build repl # Graal native-image ./build graal ``` ## Continuous Integration * [Travis](https://travis-ci.org/jline/jline3) * [AppVeyor](https://ci.appveyor.com/project/gnodet/jline3)

jknack/handlebars.java

Logic-less and semantic Mustache templates with Java

handlebars template-engine templates

[](https://patreon.com/edgarespina) [](https://maven-badges.herokuapp.com/maven-central/com.github.jknack/handlebars) [](https://javadoc.io/doc/com.github.jknack/handlebars) Handlebars.java =============== ## Logic-less and semantic Mustache templates with Java ```java Handlebars handlebars = new Handlebars(); Template template = handlebars.compileInline("Hello {{this}}!"); System.out.println(template.apply("Handlebars.java")); ``` Output: ``` Hello Handlebars.java! ``` Handlebars.java is a Java port of [handlebars](https://handlebarsjs.com/). Handlebars provides the power necessary to let you build semantic templates effectively with no frustration. [Mustache](https://mustache.github.io/mustache.5.html) templates are compatible with Handlebars, so you can take a [Mustache](https://mustache.github.io) template, import it into Handlebars, and start taking advantage of the extra Handlebars features. # Requirements - Handlebars 4.4+ requires Java 17 or higher. - Handlebars 4.3+ requires Java 8 or higher (NOT MAINTAINED). # Getting Started In general, the syntax of **Handlebars** templates is a superset of [Mustache](https://mustache.github.io) templates. For basic syntax, check out the [Mustache manpage](https://mustache.github.io). The [Handlebars.java blog](https://jknack.github.io/handlebars.java) is a good place for getting started too. Javadoc is available at [javadoc.io](https://javadoc.io/doc/com.github.jknack/handlebars). ## Maven #### Stable version: [](https://maven-badges.herokuapp.com/maven-central/com.github.jknack/handlebars) ```xml <dependency> <groupId>com.github.jknack</groupId> <artifactId>handlebars</artifactId> <version>${handlebars-version}</version> </dependency> ``` ### Loading templates Templates are loaded using the ```TemplateLoader``` class. Handlebars.java provides three implementations of a ```TemplateLoader```: * ClassPathTemplateLoader (default) * FileTemplateLoader * SpringTemplateLoader (see the [handlebars-springmvc](https://github.com/jknack/handlebars.java/tree/master/handlebars-springmvc) module) This example loads ```mytemplate.hbs``` from the root of the classpath: mytemplate.hbs: ``` Hello {{this}}! ``` ```java var handlebars = new Handlebars(); var template = handlebars.compile("mytemplate"); System.out.println(template.apply("Handlebars.java")); ``` Output: ``` Hello Handlebars.java! ``` You can specify a different ```TemplateLoader``` by: ```java TemplateLoader loader = ...; Handlebars handlebars = new Handlebars(loader); ``` #### Templates prefix and suffix A ```TemplateLoader``` provides two important properties: * ```prefix```: useful for setting a default prefix where templates are stored. * ```suffix```: useful for setting a default suffix or file extension for your templates. Default is: ```.hbs``` Example: ```java TemplateLoader loader = new ClassPathTemplateLoader(); loader.setPrefix("/templates"); loader.setSuffix(".html"); Handlebars handlebars = new Handlebars(loader); Template template = handlebars.compile("mytemplate"); System.out.println(template.apply("Handlebars.java")); ``` Handlebars.java will resolve ```mytemplate``` to ```/templates/mytemplate.html``` and load it. ## The Handlebars.java Server The handlebars.java server is small application where you can write Mustache/Handlebars template and merge them with data. It is a useful tool for Web Designers. Download from Maven Central: 1. Go [here](http://search.maven.org/#search%7Cga%7C1%7Chandlebars-proto) 2. Under the **Download** section click on **jar** Maven: ```xml <dependency> <groupId>com.github.jknack</groupId> <artifactId>handlebars-proto</artifactId> <version>${current-version}</version> </dependency> ``` Usage: ```java -jar handlebars-proto-${current-version}.jar -dir myTemplates``` Example: **myTemplates/home.hbs** ``` <ul> {{#items}} {{name}} {{/items}} </ul> ``` **myTemplates/home.json** ```json { "items": [ { "name": "Handlebars.java rocks!" } ] } ``` or if you prefer YAML **myTemplates/home.yml**: ```yml items: - name: Handlebars.java rocks! ``` ### Open a browser a type: ``` http://localhost:6780/home.hbs ``` enjoy it! ### Additional options: * -dir: set the template directory * -prefix: set the template's prefix, default is / * -suffix: set the template's suffix, default is .hbs * -context: set the context's path, default is / * -port: set port number, default is 6780 * -content-type: set the content-type header, default is text/html ### Multiple data sources per template Sometimes you need or want to test multiple datasets over a single template, you can do that by setting a ```data``` parameter in the request URI. Example: ``` http://localhost:6780/home.hbs?data=mytestdata ``` Please note you don't have to specify the extension file. ## Helpers ### Built-in helpers: * **with** * **each** * **if** * **unless** * **log** * **block** * **partial** * **precompile** * **embedded** * **i18n** and **i18nJs** * **string helpers** * **conditional helpers** ### with, each, if, unless: See the [built-in helper documentation](https://handlebarsjs.com/guide/block-helpers.html). ### block and partial Block and partial helpers work together to provide you [Template Inheritance](http://jknack.github.io/handlebars.java/reuse.html). Usage: ``` {{#block "title"}} ... {{/block}} ``` context: A string literal which defines the region's name. Usage: ``` {{#partial "title"}} ... {{/partial}} ``` context: A string literal which defines the region's name. ### precompile Precompile a Handlebars.java template to JavaScript using handlebars.js user.hbs ```html Hello {{this}}! ``` home.hbs ```html <script type="text/javascript"> {{precompile "user"}} </script> ``` Output: ```html <script type="text/javascript"> (function() { var template = Handlebars.template, templates = Handlebars.templates = Handlebars.templates || {}; templates['user'] = template(function (Handlebars,depth0,helpers,partials,data) { helpers = helpers || Handlebars.helpers; var buffer = "", functionType="function", escapeExpression=this.escapeExpression; buffer += "Hi "; depth0 = typeof depth0 === functionType ? depth0() : depth0; buffer += escapeExpression(depth0) + "!"; return buffer;}); })(); </script> ``` You can access the precompiled template with: ```js var template = Handlebars.templates['user'] ``` By default it uses: ```/handlebars-v1.3.0.js``` to compile the template. Since handlebars.java 2.x it is also possible to use handlebars.js 2.x ```java Handlebars handlebars = new Handlebars(); handlebars.handlebarsJsFile("/handlebars-v2.0.0.js"); ``` For more information have a look at the [Precompiling Templates](https://github.com/wycats/handlebars.js/) documentation. Usage: ``` {{precompile "template" [wrapper="anonymous, amd or none"]}} ``` context: A template name. Required. wrapper: One of "anonymous", "amd" or "none". Default is: "anonymous" There is a [maven plugin](https://github.com/jknack/handlebars.java/tree/master/handlebars-maven-plugin) available too. ### embedded The embedded helper allow you to "embedded" a handlebars template inside a ```<script>``` HTML tag: user.hbs ```html <tr> <td>{{firstName}}</td> <td>{{lastName}}</td> </tr> ``` home.hbs ```html <html> ... {{embedded "user"}} ... </html> ``` Output: ```html <html> ... <script id="user-hbs" type="text/x-handlebars"> <tr> <td>{{firstName}}</td> <td>{{lastName}}</td> </tr> </script> ... </html> ``` Usage: ``` {{embedded "template"}} ``` context: A template name. Required. ### i18n A helper built on top of a {@link ResourceBundle}. A {@link ResourceBundle} is the most well known mechanism for internationalization (i18n) in Java. Usage: ```html {{i18n "hello"}} ``` This require a ```messages.properties``` in the root of classpath. Using a locale: ```html {{i18n "hello" locale="es_AR"}} ``` This requires a ```messages_es_AR.properties``` in the root of classpath. Using a different bundle: ```html {{i18n "hello" bundle="myMessages"}} ``` This requires a ```myMessages.properties``` in the root of classpath. Using a message format: ```html {{i18n "hello" "Handlebars.java"}} ``` Where ```hello``` is ```Hola {0}!```, results in ```Hola Handlebars.java!```. ### i18nJs Translate a ```ResourceBundle``` into JavaScript code. The generated code assumes you have the [I18n](https://github.com/fnando/i18n-js) in your application. Usage: ``` {{i18nJs [locale] [bundle=messages]}} ``` If the locale argument is present it will translate that locale to JavaScript. Otherwise, it will use the default locale. The generated code looks like this: ```javascript <script type="text/javascript"> I18n.defaultLocale = 'es_AR'; I18n.locale = 'es_AR'; I18n.translations = I18n.translations || {}; // Spanish (Argentina) I18n.translations['es_AR'] = { "hello": "Hi {{arg0}}!" } </script> ``` Finally, it converts message patterns like: ```Hi {0}``` into ```Hi {{arg0}}```. This make possible for the [I18n](https://github.com/fnando/i18n-js) JS library to interpolate variables. ### string helpers Functions like abbreviate, capitalize, join, dateFormat, yesno, etc., are available from [StringHelpers](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/main/java/com/github/jknack/handlebars/helper/StringHelpers.java). > NOTE: You need to register string helpers (they are not added by default) ### conditional helpers Functions like eq, neq, lt, gt, and, or, not, etc., are available from [ConditionalHelpers](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/main/java/com/github/jknack/handlebars/helper/ConditionalHelpers.java). > NOTE: You need to register conditional helpers (they are not added by default) ### TypeSafe Templates TypeSafe templates are created by extending the ```TypeSafeTemplate``` interface. For example: ```java // 1 public static interface UserTemplate extends TypeSafeTemplate<User> { // 2 public UserTemplate setAge(int age); public UserTemplate setRole(String role); } // 3 UserTemplate userTmpl = handlebars.compileInline("{{name}} is {{age}} years old!") .as(UserTemplate.class); userTmpl.setAge(32); assertEquals("Edgar is 32 years old!", userTmpl.apply(new User("Edgar"))); ``` 1. You extend the ```TypeSafeTemplate``` interface. 2. You add all the set method you need. The set method can returns ```void``` or ```TypeSafeTemplate``` object. 3. You create a new type safe template using the: ```as()``` method. ### Registering Helpers There are two ways of registering helpers. #### Using the ```Helper``` interface ```java handlebars.registerHelper("blog", new Helper<Blog>() { public CharSequence apply(Blog blog, Options options) { return options.fn(blog); } }); ``` ```java handlebars.registerHelper("blog-list", new Helper<List<Blog>>() { public CharSequence apply(List<Blog> list, Options options) { String ret = "<ul>"; for (Blog blog: list) { ret += "<li>" + options.fn(blog) + "</li>"; } return new Handlebars.SafeString(ret + "</ul>"); } }); ``` #### Using a ```HelperSource``` A helper source is any class with public methods returning an instance of a ```CharSequence```. ```java public static? CharSequence methodName(context?, parameter*, options?) { } ``` Where: * A method can/can't be static * The method's name becomes the helper's name * Context, parameters and options are all optionals * If context and options are present they must be the **first** and **last** arguments of the method All these are valid definitions of helper methods: ```java public class HelperSource { public String blog(Blog blog, Options options) { return options.fn(blog); } public static String now() { return new Date().toString(); } public String render(Blog context, String param0, int param1, boolean param2, Options options) { return ... } } ... handlebars.registerHelpers(new HelperSource()); ``` Or, if you prefer static methods only: ```java handlebars.registerHelpers(HelperSource.class); ``` #### With plain ```JavaScript``` That's right since ```1.1.0``` you can write helpers in JavaScript: helpers.js: ```javascript Handlebars.registerHelper('hello', function (context) { return 'Hello ' + context; }) ``` ```java handlebars.registerHelpers(new File("helpers.js")); ``` Cool, isn't? ### Helper Options #### Parameters ```java handlebars.registerHelper("blog-list", new Helper<Blog>() { public CharSequence apply(List<Blog> list, Options options) { String p0 = options.param(0); assertEquals("param0", p0); Integer p1 = options.param(1); assertEquals(123, p1); ... } }); Bean bean = new Bean(); bean.setParam1(123); Template template = handlebars.compileInline("{{#blog-list blogs \"param0\" param1}}{{/blog-list}}"); template.apply(bean); ``` #### Default parameters ```java handlebars.registerHelper("blog-list", new Helper<Blog>() { public CharSequence apply(List<Blog> list, Options options) { String p0 = options.param(0, "param0"); assertEquals("param0", p0); Integer p1 = options.param(1, 123); assertEquals(123, p1); ... } }); Template template = handlebars.compileInline("{{#blog-list blogs}}{{/blog-list}}"); ``` #### Hash ```java handlebars.registerHelper("blog-list", new Helper<Blog>() { public CharSequence apply(List<Blog> list, Options options) { String class = options.hash("class"); assertEquals("blog-css", class); ... } }); handlebars.compileInline("{{#blog-list blogs class=\"blog-css\"}}{{/blog-list}}"); ``` #### Default hash ```java handlebars.registerHelper("blog-list", new Helper<Blog>() { public CharSequence apply(List<Blog> list, Options options) { String class = options.hash("class", "blog-css"); assertEquals("blog-css", class); ... } }); handlebars.compileInline("{{#blog-list blogs}}{{/blog-list}}"); ``` ## Error reporting ### Syntax errors ``` file:line:column: message evidence ^ [at file:line:column] ``` Examples: template.hbs ``` {{value ``` ``` /templates.hbs:1:8: found 'eof', expected: 'id', 'parameter', 'hash' or '}' {{value ^ ``` If a partial isn't found or if it has errors, a call stack is added: ``` /deep1.hbs:1:5: The partial '/deep2.hbs' could not be found {{> deep2 ^ at /deep1.hbs:1:10 at /deep.hbs:1:10 ``` ### Helper/Runtime errors Helper or runtime errors are similar to syntax errors, except for two things: 1. The location of the problem may (or may not) be the correct one 2. The stack-trace isn't available Examples: Block helper: ```java public CharSequence apply(final Object context, final Options options) throws IOException { if (context == null) { throw new IllegalArgumentException( "found 'null', expected 'string'"); } if (!(context instanceof String)) { throw new IllegalArgumentException( "found '" + context + "', expected 'string'"); } ... } ``` base.hbs ``` {{#block}} {{/block}} ``` Handlebars.java reports: ``` /base.hbs:2:4: found 'null', expected 'string' {{#block}} ... {{/block}} ``` In short, from a helper you can throw an Exception and Handlebars.java will add the filename, line, column and the evidence. ## Advanced Usage ### Extending the context stack Let's say you need to access to the current logged-in user in every single view/page. You can publish the current logged in user by hooking into the context-stack. See it in action: ```java hookContextStack(Object model, Template template) { User user = ....;// Get the logged-in user from somewhere Map moreData = ...; Context context = Context .newBuilder(model) .combine("user", user) .combine(moreData) .build(); template.apply(context); context.destroy(); } ``` Where is the ```hookContextStack``` method? Well, it depends on your application architecture. ### Using the ValueResolver By default, Handlebars.java use the JavaBean methods (i.e. public getXxx and isXxx methods) and Map as value resolvers. You can choose a different value resolver. This section describe how to do this. #### The JavaBeanValueResolver Resolves values from public methods prefixed with "get/is" ```java Context context = Context .newBuilder(model) .resolver(JavaBeanValueResolver.INSTANCE) .build(); ``` #### The FieldValueResolver Resolves values from no-static fields. ```java Context context = Context .newBuilder(model) .resolver(FieldValueResolver.INSTANCE) .build(); ``` #### The MapValueResolver Resolves values from a ```java.util.Map``` objects. ```java Context context = Context .newBuilder(model) .resolver(MapValueResolver.INSTANCE) .build(); ``` #### The MethodValueResolver Resolves values from public methods. ```java Context context = Context .newBuilder(model) .resolver(MethodValueResolver.INSTANCE) .build(); ``` #### The JsonNodeValueResolver Resolves values from ```JsonNode``` objects. ```java Context context = Context .newBuilder(model) .resolver(JsonNodeValueResolver.INSTANCE) .build(); ``` Available in [Jackson 1.x](https://github.com/jknack/handlebars.java/tree/master/handlebars-json) and [Jackson 2.x](https://github.com/jknack/handlebars.java/tree/master/handlebars-jackson2) modules. #### Using multiples value resolvers ```java Context context = Context .newBuilder(model) .resolver( MapValueResolver.INSTANCE, JavaBeanValueResolver.INSTANCE, FieldValueResolver.INSTANCE ).build(); ``` ### The Cache System The cache system is designed to provide scalability and flexibility. Here is a quick view of the ```TemplateCache``` system: ```java public interface TemplateCache { /** * Remove all mappings from the cache. */ void clear(); /** * Evict the mapping for this source from this cache if it is present. * * @param source the source whose mapping is to be removed from the cache */ void evict(TemplateSource source); /** * Return the value to which this cache maps the specified key. * * @param source source whose associated template is to be returned. * @param parser The Handlebars parser. * @return A template. * @throws IOException If input can't be parsed. */ Template get(TemplateSource source, Parser parser) throws IOException; } ``` As you can see, there isn't a ```put``` method. All the hard work is done in the ```get``` method, which is basically the core of the cache system. By default, Handlebars.java uses a ```null``` cache implementation (a.k.a. no cache at all) which looks like: ``` Template get(TemplateSource source, Parser parser) throws IOException { return parser.parse(source); } ``` In addition to the ```null``` cache, Handlebars.java provides three more implementations: 1. ```ConcurrentMapTemplateCache```: a template cache implementation built on top of a ```ConcurrentMap``` that detects changes in files automatically. This implementation works very well in general, but there is a small window where two or more threads can compile the same template. This isn't a huge problem with Handlebars.java because the compiler is very very fast. But if for some reason you don't want this, you can use the ```HighConcurrencyTemplateCache``` template cache. 2. ```HighConcurrencyTemplateCache```: a template cache implementation built on top of ```ConcurrentMap``` that detects changes in files automatically. This cache implementation eliminates the window created by ```ConcurrentMapTemplateCache``` to ```zero```. It follows the patterns described in [Java Concurrency in Practice](http://www.amazon.com/Java-Concurrency-Practice-Brian-Goetz/dp/0321349601) and ensures that a template will be compiled just once regardless of the number of threads. 3. ```GuavaTemplateCache```: a template cache implementation built on top of [Google Guava](https://code.google.com/p/guava-libraries/wiki/CachesExplained). Available in [handlebars-guava-cache module](https://github.com/jknack/handlebars.java/tree/master/handlebars-guava-cache) You can configure Handlebars.java to use a cache by: ``` Handlebars hbs = new Handlebars() .with(new MyCache()); ``` ### Using a MissingValueResolver (@deprecated) NOTE: MissingValueResolver is available in ```<= 1.3.0```. For ```> 1.3.0``` use [Helper Missing](https://github.com/jknack/handlebars.java#helper-missing). A ```MissingValueResolver``` let you use default values for ```{{variable}}``` expressions resolved to ```null```. ```java MissingValueResolver missingValueResolver = new MissingValueResolver() { public String resolve(Object context, String name) { //return a default value or throw an exception ...; } }; Handlebars handlebars = new Handlebars().with(missingValueResolver); ``` ### Helper Missing By default, Handlebars.java throws an ```java.lang.IllegalArgumentException()``` if a helper cannot be resolved. You can override the default behaviour by providing a special helper: ```helperMissing```. Example: ```java handlebars.registerHelperMissing(new Helper<Object>() { @Override public CharSequence apply(final Object context, final Options options) throws IOException { return options.fn.text(); } }); ``` ### String form parameters You can access a parameter name if you set the: ```stringParams: true```. Example: ```html {{sayHi this edgar}} ``` ```java Handlebars handlebars = new Handlebars() .stringParams(true); handlebars.registerHelper("sayHi", new Helper<Object>() { public Object apply(Object context, Options options) { return "Hello " + options.param(0) + "!"; } }); ``` results in: ``` Hello edgar! ``` How does this work? ```stringParams: true``` instructs Handlebars.java to resolve a parameter to it's name if the value isn't present in the context stack. ### Allow Infinite loops By default, Handlebars.java doesn't allow a partial to call itself (directly or indirectly). You can change this by setting the: ```Handlebars.inifiteLoops(true)```, but watch out for a ```StackOverflowError```. ### Pretty Print The Mustache Spec has some rules for removing spaces and new lines. This feature is disabled by default. You can turn this on by setting the: ```Handlebars.prettyPrint(true)```. # Modules ## Jackson 1.x Maven: ```xml <dependency> <groupId>com.github.jknack</groupId> <artifactId>handlebars-json</artifactId> <version>${handlebars-version}</version> </dependency> ``` Usage: ```java handlebars.registerHelper("json", JacksonHelper.INSTANCE); ``` ``` {{json context [view="foo.MyFullyQualifiedClassName"] [escapeHTML=false] [pretty=false]}} ``` Alternative: ```java handlebars.registerHelper("json", new JacksonHelper().viewAlias("myView", foo.MyFullyQualifiedClassName.class); ``` ``` {{json context [view="myView"] [escapeHTML=false] [pretty=false]}} ``` context: An object, may be null. view: The name of the [Jackson View](http://wiki.fasterxml.com/JacksonJsonViews). Optional. escapeHTML: True, if the JSON content contains HTML chars and you need to escaped them. Default is: false. pretty: True, if the JSON content must be formatted. Default is: false. ## Jackson Maven: ```xml <dependency> <groupId>com.github.jknack</groupId> <artifactId>handlebars-jackson</artifactId> <version>${handlebars-version}</version> </dependency> ``` ## SpringMVC Maven: ```xml <dependency> <groupId>com.github.jknack</groupId> <artifactId>handlebars-springmvc</artifactId> <version>${handlebars-version}</version> </dependency> ``` Using value resolvers: ```java HandlebarsViewResolver viewResolver = ...; viewResolver.setValueResolvers(...); ``` In addition, the HandlebarsViewResolver add a ```message``` helper that uses the Spring ```MessageSource``` class: ``` {{message "code" [arg]* [default="default message"]}} ``` where: * code: the message's code. Required. * arg: the message's argument. Optional. * default: the default's message. Optional. Checkout the [HandlebarsViewResolver](https://github.com/jknack/handlebars.java/blob/master/handlebars-springmvc/src/main/java/com/github/jknack/handlebars/springmvc/HandlebarsViewResolver.java). # Performance Handlebars.java is a modern and full featured template engine, but also has a very good performance (Hbs):  Benchmark source code is available at: https://github.com/mbosecke/template-benchmark # Architecture and API Design * Handlebars.java follows the JavaScript API with some minors exceptions due to the nature of the Java language. * The parser is built on top of [ANTLR v4] (http://www.antlr.org/). * Data is provided as primitive types (int, boolean, double, etc.), strings, maps, list or JavaBeans objects. * Helpers are type-safe. * Handlebars.java is thread-safe. ## Differences between Handlebars.java and Handlebars.js Handlebars.java scope resolution follows the Mustache Spec. For example: Given: ```json { "value": "parent", "child": { } } ``` and ```html Hello {{#child}}{{value}}{{/child}} ``` will be: ```html Hello parent ``` Now, the same model and template with Handlebars.js is: ```html Hello ``` That is because Handlebars.js doesn't look in the context stack for missing attributes in the current scope (this is consistent with the Mustache Spec). Hopefully, you can turn-off the context stack lookup in Handlebars.java by qualifying the attribute with ```this.```: ```html Hello {{#child}}{{this.value}}{{/child}} ``` ## Differences between Handlebars.java and Mustache.js * Handlebars.java throws a ```java.io.FileNotFoundException``` if a partial cannot be loaded. ## Status ### Mustache 1.0 Compliant * Passes the 123 tests from the [Mustache Spec](https://github.com/mustache/spec). * Tests can be found here [comments.yml](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/specs/CommentsTest.java), [delimiters.yml](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/specs/DelimitersTest.java), [interpolation.yml](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/specs/InterpolationTest.java), [inverted.yml](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/specs/InvertedTest.java), [lambdas.yml](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/specs/LambdasTest.java), [partials.yml](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/specs/PartialsTest.java), [sections.yml](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/specs/SectionsTest.java) ### Handlebars.js Compliant * Passes all the [Handlebars.js tests](https://github.com/wycats/handlebars.js/blob/master/spec/qunit_spec.js) * Tests can be found here [basic context](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/hbs/js/BasicContextTest.java), [string literals](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/hbs/js/StringLiteralParametersTest.java), [inverted sections](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/hbs/js/InvertedSectionTest.java), [blocks](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/hbs/js/BlockTest.java), [block helper missing](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/hbs/js/BlockHelperMissingTest.java), [helper hash](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/hbs/js/HelperHashTest.java), [partials](https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/hbs/js/PartialsTest.java) ## Dependencies ```text +- org.slf4j:slf4j-api:jar:1.6.4 ``` ## FAQ ## Want to contribute? * Fork the project on Github. * Wondering what to work on?

Google suggested a job title of SRE (Site Reliability Engineer) in 2003. It consists of a team of software engineers and system administrators who place a premium on O & M personnel's development skills, forcing them to devote less than half of their time to daily tasks and the other half to the creation of automation technologies to decrease labor needs. SREWorks focuses on the application-centric one-stop "cloud native" and "DataOps and AIOps" O & M SaaS management suite as an engineering practice for the Alibaba Cloud Big Data SRE team's SRE concept. It enables companies to achieve the delivery and maintenance of cloud-native apps and resources via two primary capabilities: enterprise application and resource management and O & M development. Alibaba Cloud Big Data SRE team has been working hard to practice the "DataOps and AIOps" concept, the industry's DataOps (data operation and maintenance) first proposed by the team, is naturally close to big data and AI, is very familiar with Big Data & AI technology, and has the big data and AI computing power resources on demand, has been working hard to practice the "DataOps and AIOps" concept, the industry's DataOps Standard O & M warehouses, data O & M platforms, and operation centers are among the end-to-end DataOps closed-loop engineering methods in the SREWorks. There are many excellent open-source O & M platforms that reflect cloud-native scenarios in the traditional IT O&M field. There are currently no systematic O & M solutions available.

As the heart of Apache ShenYu, plugins are extensible and hot-pluggable. Different plugins do different things. Of course, users can also customize plugins to meet their own needs. If you want to customize, see [custom-plugin](https://shenyu.apache.org/docs/developer/custom-plugin/) . --- # Selector & Rule According to your HTTP request headers, selectors and rules are used to route your requests. Selector is your first route, It is coarser grained, for example, at the module level. Rule is your second route and what do you think your request should do. For example a method level in a module. The selector and the rule match only once, and the match is returned. So the coarsest granularity should be sorted last. --- # Data Caching & Data Sync Since all data have been cached using ConcurrentHashMap in the JVM, it's very fast. Apache ShenYu dynamically updates the cache by listening to the ZooKeeper node (or WebSocket push, HTTP long polling) when the user changes configuration information in the background management.   --- # Prerequisite * JDK 1.8+ --- # Stargazers over time [](https://starchart.cc/apache/shenyu.svg) --- # Contributor and Support * [How to Contribute](https://shenyu.apache.org/community/contributor-guide) * [Mailing Lists](mailto:dev@shenyu.apache.org) --- # Known Users In order of registration, More access companies are welcome to register at [https://github.com/apache/shenyu/issues/68](https://github.com/apache/shenyu/issues/68) (For open source users only) .

openzipkin/brave

Java distributed tracing implementation compatible with Zipkin backend services.

distributed-tracing instrumentation java openzipkin tracing zipkin zipkin-brave

[](https://gitter.im/openzipkin/zipkin) [](https://github.com/openzipkin/brave/actions?query=workflow%3Atest) [](https://search.maven.org/search?q=g:io.zipkin.brave%20AND%20a:brave) # Brave Brave is a distributed tracing instrumentation library. Brave typically intercepts production requests to gather timing data, correlate and propagate trace contexts. While typically trace data is sent to [Zipkin server](https://github.com/openzipkin/zipkin/tree/master/zipkin-server), third-party plugins are available to send to alternate services such as [Amazon X-Ray](https://github.com/openzipkin/zipkin-aws/tree/master/storage/xray-udp). This repository includes dependency-free Java libraries and instrumentation for common components used in production services. For example, this includes trace filters for Servlet and log correlation for Apache Log4J. You can look at our [example project](https://github.com/openzipkin/brave-webmvc-example) for how to trace a simple web application. ## What's included Brave's dependency-free [tracer library](brave/) works against JRE6+. This is the underlying api that instrumentation use to time operations and add tags that describe them. This library also includes code that parses `X-B3-TraceId` headers. Most users won't write tracing code directly. Rather, they reuse instrumentation others have written. Check our [instrumentation](instrumentation/) and [Zipkin's list](https://zipkin.io/pages/tracers_instrumentation.html) before rolling your own. Common tracing libraries like JDBC, Servlet and Spring already exist. Instrumentation written here are tested and benchmarked. If you are trying to trace legacy applications, you may be interested in [Spring XML Configuration](spring-beans/). This allows you to set up tracing without any custom code. You may want to put trace IDs into your log files, or change thread local behavior. Look at our [context libraries](context/), for integration with tools such as SLF4J. ## Version Compatibility policy All Brave libraries match the minimum Java version of what's being traced or integrated with, and adds no 3rd party dependencies. The goal is to neither impact your projects' choices, nor subject your project to dependency decisions made by others. For example, even including a basic reporting library, [zipkin-sender-urlconnection](https://github.com/openzipkin/zipkin-reporter-java), Brave transitively includes no json, logging, protobuf or thrift dependency. This means zero concern if your application chooses a specific version of SLF4J, Gson or Guava. Moreover, the entire dependency tree including basic reporting in json, thrift or protobuf is less than 512KiB of jars. There is a floor Java version of 1.6, which allows older JREs and older Android runtimes, yet may limit some applications. For example, Servlet 2.5 works with Java 1.5, but due to Brave being 1.6, you will not be able to trace Servlet 2.5 applications until you use at least JRE 1.6. All integrations set their associated library to "provided" scope. This ensures Brave doesn't interfere with the versions you choose. Some libraries update often which leads to api drift. In some cases, we test versions ranges to reduce the impact of this. For example, we test [gRPC](instrumentation/grpc) and [Kafka](instrumentation/kafka-clients) against multiple library versions. ## Artifacts All artifacts publish to the group ID "io.zipkin.brave". We use a common release version for all components. ### Library Releases Snapshots are uploaded to [Sonatype](https://oss.sonatype.org/content/repositories/releases) which synchronizes with [Maven Central](http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22io.zipkin.brave%22) ### Library Snapshots Snapshots are uploaded to [Sonatype](https://oss.sonatype.org/content/repositories/snapshots) after commits to master. ### Version alignments When using multiple brave components, you'll want to align versions in one place. This allows you to more safely upgrade, with less worry about conflicts. You can use our Maven instrumentation BOM (Bill of Materials) for this: Ex. in your dependencies section, import the BOM like this: ```xml <dependencyManagement> <dependencies> <dependency> <groupId>io.zipkin.brave</groupId> <artifactId>brave-bom</artifactId> <version>${brave.version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> ``` Now, you can leave off the version when choosing any supported instrumentation. Also, any indirect use will have versions aligned: ```xml <dependency> <groupId>io.zipkin.brave</groupId> <artifactId>brave-instrumentation-okhttp3</artifactId> </dependency> ``` With the above in place, you can use the property `brave.version` to override dependency versions coherently. This is most commonly to test a new feature or fix. Note: If you override a version, always double check that your version is valid (equal to or later) than what you are updating. This will avoid class conflicts.

CaffeineMC/sodium-fabric

A Fabric mod designed to improve frame rates and reduce micro-stutter

azdo fabric minecraft opengl

<img src="src/main/resources/assets/sodium/icon.png" width="128"> # Sodium (for Fabric) Sodium is a powerful rendering engine and optimization mod for the Minecraft client which improves frame rates and reduces micro-stutter, while fixing many graphical issues in Minecraft. ### 📥 Installation The latest releases of Sodium are published to our official [Modrinth](https://modrinth.com/mod/sodium) and [GitHub release](https://github.com/CaffeineMC/sodium-fabric/releases) pages. These releases are considered by our team to be suitable for general use, but they are not guaranteed to be free of bugs and other issues. For more information about downloading and installing the mod, you can read our installation guide on [Modrinth](https://modrinth.com/mod/sodium#installation). It also contains information about any currently known compatibility issues, which are often useful to read. ### 🐛 Reporting Issues You can report bugs and crashes by opening an issue on our [issue tracker](https://github.com/CaffeineMC/sodium-fabric/issues). Before opening a new issue, use the search tool to make sure that your issue has not already been reported and ensure that you have completely filled out the issue template. Issues that are duplicates or do not contain the necessary information to triage and debug may be closed. Please note that while the issue tracker is open to feature requests, development is primarily focused on improving hardware compatibility, performance, and finishing any unimplemented features necessary for parity with the vanilla renderer. ### 💬 Join the Community We have an [official Discord community](https://caffeinemc.net/discord) for all of our projects. By joining, you can: - Get installation help and technical support for all of our mods - Get the latest updates about development and community events - Talk with and collaborate with the rest of our team - ... and just hang out with the rest of our community. ## ✅ Hardware Compatibility We only provide support for graphics cards which have up-to-date drivers for OpenGL 4.6. Most graphics cards which have been released since year 2010 are supported, such as the... - AMD Radeon HD 7000 Series (GCN 1) or newer - NVIDIA GeForce 400 Series (Fermi) or newer - Intel HD Graphics 500 Series (Skylake) or newer In some cases, older graphics cards may also work (so long as they have up-to-date drivers which have support for OpenGL 3.3), but they are not officially supported, and may not be compatible with future versions of Sodium. #### OpenGL Compatibility Layers Devices which need to use OpenGL translation layers (such as GL4ES, ANGLE, etc) are not supported and will very likely not work with Sodium. These translation layers do not implement required functionality and they suffer from underlying driver bugs which cannot be worked around. ## 🛠️ Developer Guide ### Building from sources Sodium uses a typical Gradle project structure and can be compiled by simply running the default `build` task. The build artifacts (typical mod binaries, and their sources) can be found in the `build/libs` directory. #### Requirements We recommend using a package manager (such as [SDKMAN](https://sdkman.io/)) to manage toolchain dependencies and keep them up to date. For many Linux distributions, these dependencies will be standard packages in your software repositories. - OpenJDK 17 - We recommend using the [Eclipse Temurin](https://adoptium.net/) distribution, as it's known to be high quality and to work without issues. - Gradle 8.2.1 (optional) - The [Gradle wrapper](https://docs.gradle.org/current/userguide/gradle_wrapper.html#sec:using_wrapper) is provided in this repository can be used instead of installing a suitable version of Gradle yourself. However, if you are building many projects, you may prefer to install it yourself through a suitable package manager as to save disk space and to avoid many different Gradle daemons sitting around in memory. - Typically, newer versions of Gradle will work without issues, but the build script is only tested against the version specified by the wrapper script. ## 📜 License Except where otherwise stated, the content of this repository is provided under the [Polyform Shield 1.0.0](LICENSE.md) license by [JellySquid](https://jellysquid.me).

confluentinc/kafka-streams-examples

Demo applications and code examples for Apache Kafka's Streams API.

# Kafka Streams Examples This project contains code examples that demonstrate how to implement real-time applications and event-driven microservices using the Streams API of [Apache Kafka](http://kafka.apache.org/) aka Kafka Streams. For more information take a look at the [**latest Confluent documentation on the Kafka Streams API**](http://docs.confluent.io/current/streams/), notably the [**Developer Guide**](https://docs.confluent.io/platform/current/streams/developer-guide/index.html) --- Table of Contents * [Available examples](#available-examples) * [Examples: Runnable Applications](#examples-apps) * [Examples: Unit Tests](#examples-unit-tests) * [Examples: Integration Tests](#examples-integration-tests) * [Docker Example: Kafka Music demo application](#examples-docker) * [Examples: Event Streaming Platform](#examples-event-streaming-platform) * [Requirements](#requirements) * [Apache Kafka](#requirements-kafka) * [Confluent Platform](#requirements-confluent-platform) * [Using IntelliJ or Eclipse](#requirements-ide) * [Java](#requirements-java) * [Scala](#requirements-scala) * [Packaging and running the examples](#packaging-and-running) * [Development](#development) * [Version Compatibility Matrix](#version-compatibility) * [Where to find help](#help) --- <a name="available-examples"/> # Available examples This repository has several branches to help you find the correct code examples for the version of Apache Kafka and/or Confluent Platform that you are using. See [Version Compatibility Matrix](#version-compatibility) below for details. There are three kinds of examples: * **Examples under [src/main/](src/main/)**: These examples are short and concise. Also, you can interactively test-drive these examples, e.g. against a local Kafka cluster. If you want to actually run these examples, then you must first install and run Apache Kafka and friends, which we describe in section [Packaging and running the examples](#packaging-and-running). Each example also states its exact requirements and instructions at the very top. * **Examples under [src/test/](src/test/)**: These examples should test applications under [src/main/](src/main/). Unit Tests with TopologyTestDriver test the stream logic without external system dependencies. The integration tests use an embedded Kafka clusters, feed input data to them (using the standard Kafka producer client), process the data using Kafka Streams, and finally read and verify the output results (using the standard Kafka consumer client). These examples are also a good starting point to learn how to implement your own end-to-end integration tests. * **Ready-to-run Docker Examples**: These examples are already built and containerized. <a name="examples-apps"/> ## Examples: Runnable Applications Additional examples may be found under [src/main/](src/main/java/io/confluent/examples/streams/). | Application Name | Concepts used | Java 8+ | Java 7+ | Scala | | --------------------------- | -------------------------------------------------------- | ------- | ------- | ----- | | WordCount | DSL, aggregation, stateful | [Java 8+ example](src/main/java/io/confluent/examples/streams/WordCountLambdaExample.java) | | [Scala Example](src/main/scala/io/confluent/examples/streams/WordCountScalaExample.scala) | | MapFunction | DSL, stateless transformations, `map()` | [Java 8+ example](src/main/java/io/confluent/examples/streams/MapFunctionLambdaExample.java) | | [Scala Example](src/main/scala/io/confluent/examples/streams/MapFunctionScalaExample.scala) | | SessionWindows | Sessionization of user events, user behavior analysis | | [Java 7+ example](src/main/java/io/confluent/examples/streams/SessionWindowsExample.java) | GlobalKTable | `join()` between `KStream` and `GlobalKTable` | [Java 8+ example](src/main/java/io/confluent/examples/streams/GlobalKTablesExample.java) | | | | GlobalStore | "join" between `KStream` and `GlobalStore` | [Java 8+ example](src/main/java/io/confluent/examples/streams/GlobalStoresExample.java) | | | | PageViewRegion | `join()` between `KStream` and `KTable` | [Java 8+ example](src/main/java/io/confluent/examples/streams/PageViewRegionLambdaExample.java) | [Java 7+ example](src/main/java/io/confluent/examples/streams/PageViewRegionExample.java) | | | PageViewRegionGenericAvro | Working with data in Generic Avro format | [Java 8+ example](src/main/java/io/confluent/examples/streams/PageViewRegionLambdaExample.java) | [Java 7+ example](src/main/java/io/confluent/examples/streams/PageViewRegionExample.java) | | | WikipediaFeedSpecificAvro | Working with data in Specific Avro format | [Java 8+ example](src/main/java/io/confluent/examples/streams/WikipediaFeedAvroLambdaExample.java) | [Java 7+ example](src/main/java/io/confluent/examples/streams/WikipediaFeedAvroExample.java) | | | SecureKafkaStreams | Secure, encryption, client authentication | | [Java 7+ example](src/main/java/io/confluent/examples/streams/SecureKafkaStreamsExample.java) | | | Sum | DSL, stateful transformations, `reduce()` | [Java 8+ example](src/main/java/io/confluent/examples/streams/SumLambdaExample.java) | | | | WordCountInteractiveQueries | Interactive Queries, REST, RPC | [Java 8+ example](src/main/java/io/confluent/examples/streams/interactivequeries/WordCountInteractiveQueriesExample.java) | | | | KafkaMusic | Interactive Queries, State Stores, REST API | [Java 8+ example](src/main/java/io/confluent/examples/streams/interactivequeries/kafkamusic/KafkaMusicExample.java) | | | | ApplicationReset | Application Reset Tool `kafka-streams-application-reset` | [Java 8+ example](src/main/java/io/confluent/examples/streams/ApplicationResetExample.java) | | | | Microservice | Microservice ecosystem, state stores, dynamic routing, joins, filtering, branching, stateful operations | [Java 8+ example](src/main/java/io/confluent/examples/streams/microservices) | | | <a name="examples-unit-tests"/> ## Examples: Unit Tests The stream processing of Kafka Streams can be **unit tested** with the `TopologyTestDriver` from the `org.apache.kafka:kafka-streams-test-utils` artifact. The test driver allows you to write sample input into your processing topology and validate its output. See the documentation at [Testing Streams Code](https://docs.confluent.io/current/streams/developer-guide/test-streams.html). <a name="examples-integration-tests"/> ## Examples: Integration Tests We also provide several **integration tests**, which demonstrate end-to-end data pipelines. Here, we spawn embedded Kafka clusters and the [Confluent Schema Registry](https://github.com/confluentinc/schema-registry), feed input data to them (using the standard Kafka producer client), process the data using Kafka Streams, and finally read and verify the output results (using the standard Kafka consumer client). Additional examples may be found under [src/test/](src/test/java/io/confluent/examples/streams/). > Tip: Run `mvn test` to launch the tests. | Integration Test Name | Concepts used | Java 8+ | Java 7+

It exposes its latest processing results -- the latest charts -- via Kafka’s [Interactive Queries](http://docs.confluent.io/current/streams/developer-guide.html#interactive-queries) feature via a REST API. The application's input data is in Avro format, hence the use of Confluent Schema Registry, and comes from two sources: a stream of play events (think: "song X was played") and a stream of song metadata ("song X was written by artist Y"). You can find detailed documentation at https://docs.confluent.io/current/streams/kafka-streams-examples/docs/index.html. <a name="event-streaming-platform"/> # Examples: Event Streaming Platform For additional examples that showcase Kafka Streams applications within an event streaming platform, please refer to the [examples GitHub repository](https://github.com/confluentinc/examples). <a name="requirements"/> # Requirements <a name="requirements-kafka"/> ## Apache Kafka The code in this repository requires Apache Kafka 0.10+ because from this point onwards Kafka includes its [Kafka Streams](https://github.com/apache/kafka/tree/trunk/streams) library. See [Version Compatibility Matrix](#version-compatibility) for further details, as different branches of this repository may have different Kafka requirements. > **For the `master` branch:** To build a development version, you typically need the latest `trunk` version of Apache Kafka > (cf. `kafka.version` in [pom.xml](pom.xml) for details).

See [Version Compatibility Matrix](#version-compatibility) for further details, as different branches of this repository have different Confluent Platform requirements. * [Confluent Platform Quickstart](http://docs.confluent.io/current/quickstart.html) (how to download and install) * [Confluent Platform documentation](http://docs.confluent.io/current/) > **For the `master` branch:** To build a development version, you typically need the latest `master` version of Confluent Platform's > Schema Registry (cf. `confluent.version` in [pom.xml](pom.xml), which is set by the upstream > [Confluent Common](https://github.com/confluentinc/common) project). > The following instructions will build and locally install the latest `master` Schema Registry version, which includes > building its dependencies such as [Confluent Common](https://github.com/confluentinc/common) and > [Confluent Rest Utils](https://github.com/confluentinc/rest-utils). > Please read the [Schema Registry README](https://github.com/confluentinc/schema-registry) for details. > > ```shell > $ git clone https://github.com/confluentinc/common.git > $ cd common > $ git checkout master > > # Build and install common locally > $ mvn -DskipTests=true clean install > > $ git clone https://github.com/confluentinc/rest-utils.git > $ cd rest-utils > $ git checkout master > > # Build and install rest-utils locally > $ mvn -DskipTests=true clean install > > $ git clone https://github.com/confluentinc/schema-registry.git > $ cd schema-registry > $ git checkout master > > # Now build and install schema-registry locally > $ mvn -DskipTests=true clean install > ``` Also, each example states its exact requirements at the very top. <a name="requirements-ide"/> ## Using IntelliJ or Eclipse If you are using an IDE and import the project you might end up with a "missing import / class not found" error. Some Avro classes are generated from schema files and IDEs sometimes do not generate these classes automatically. To resolve this error, manually run: ```shell $ mvn -Dskip.tests=true compile ``` If you are using Eclipse, you can also right-click on `pom.xml` file and choose _Run As > Maven generate-sources_. <a name="requirements-java"/> ## Java 8+ Some code examples require Java 8+, primarily because of the usage of [lambda expressions](https://docs.oracle.com/javase/tutorial/java/javaOO/lambdaexpressions.html). IntelliJ IDEA users: * Open _File > Project structure_ * Select "Project" on the left. * Set "Project SDK" to Java 1.8. * Set "Project language level" to "8 - Lambdas, type annotations, etc." <a name="requirements-scala"/> ## Scala > Scala is required only for the Scala examples in this repository. If you are a Java developer you can safely ignore > this section. If you want to experiment with the Scala examples in this repository, you need a version of Scala that supports Java 8 and SAM / Java lambda (e.g. Scala 2.11 with `-Xexperimental` compiler flag, or 2.12). If you are compiling with Java 9+, you'll need to have Scala version 2.12+ to be compatible with the Java version. <a name="packaging-and-running"/> # Packaging and running the Application Examples The instructions in this section are only needed if you want to interactively test-drive the [application examples](#examples-apps) under [src/main/](src/main/). > **Tip:** If you only want to run the integration tests (`mvn test`), then you do not need to package or install > anything -- just run `mvn test`. These tests launch embedded Kafka clusters. The first step is to install and run a Kafka cluster, which must consist of at least one Kafka broker as well as at least one ZooKeeper instance. Some examples may also require a running instance of Confluent schema registry. The [Confluent Platform Quickstart](http://docs.confluent.io/current/quickstart.html) guide provides the full details. In a nutshell: ```shell # Ensure you have downloaded and installed Confluent Platform as per the Quickstart instructions above. # Start ZooKeeper $ ./bin/zookeeper-server-start ./etc/kafka/zookeeper.properties # In a separate terminal, start Kafka broker $ ./bin/kafka-server-start ./etc/kafka/server.properties # In a separate terminal, start Confluent Schema Registry $ ./bin/schema-registry-start ./etc/schema-registry/schema-registry.properties # Again, please refer to the Confluent Platform Quickstart for details such as # how to download Confluent Platform, how to stop the above three services, etc. ``` The next step is to create a standalone jar ("fat jar") of the [application examples](#examples-apps): ```shell # Create a standalone jar ("fat jar") $ mvn clean package # >>> Creates target/kafka-streams-examples-7.8.0-0-standalone.jar ``` > Tip: If needed, you can disable the test suite during packaging, for example to speed up the packaging or to lower > JVM memory usage: > > ```shell > $ mvn -DskipTests=true clean package > ``` You can now run the application examples as follows: ```shell # Run an example application from the standalone jar. Here: `WordCountLambdaExample` $ java -cp target/kafka-streams-examples-7.8.0-0-standalone.jar \ io.confluent.examples.streams.WordCountLambdaExample ``` The application will try to read from the specified input topic (in the above example it is ``streams-plaintext-input``), execute the processing logic, and then try to write back to the specified output topic (in the above example it is ``streams-wordcount-output``). In order to observe the expected output stream, you will need to start a console producer to send messages into the input topic and start a console consumer to continuously read from the output topic. More details in how to run the examples can be found in the [java docs](src/main/java/io/confluent/examples/streams/WordCountLambdaExample.java#L31) of each example code. If you want to turn on log4j while running your example application, you can edit the [log4j.properties](src/main/resources/log4j.properties) file and then execute as follows: ```shell # Run an example application from the standalone jar. Here: `WordCountLambdaExample` $ java -cp target/kafka-streams-examples-7.8.0-0-standalone.jar \ -Dlog4j.configuration=file:src/main/resources/log4j.properties \ io.confluent.examples.streams.WordCountLambdaExample ``` Keep in mind that the machine on which you run the command above must have access to the Kafka/ZooKeeper clusters you configured in the code examples. By default, the code examples assume the Kafka cluster is accessible via `localhost:9092` (aka Kafka's ``bootstrap.servers`` parameter) and the ZooKeeper ensemble via `localhost:2181`. You can override the default ``bootstrap.servers`` parameter through a command line argument. <a name="development"/> # Development This project uses the standard maven lifecycle and commands such as: ```shell $ mvn compile # This also generates Java classes from the Avro schemas $ mvn test # Runs unit and integration tests $ mvn package # Packages the application examples into a standalone jar ``` <a name="version-compatibility"/> # Version Compatibility Matrix | Branch (this repo) | Confluent Platform | Apache Kafka | | ----------------------------------------|--------------------|-------------------| | [5.4.x](../../../tree/5.4.x/)\* | 5.4.0-SNAPSHOT | 2.4.0-SNAPSHOT | | [5.3.0-post](../../../tree/5.3.0-post/) | 5.3.0 | 2.3.0 | | [5.2.2-post](../../../tree/5.2.2-post/) | 5.2.2 | 2.2.1 | | [5.2.1-post](../../../tree/5.2.1-post/) | 5.2.1 | 2.2.1 | | [5.1.0-post](../../../tree/5.1.0-post/) | 5.1.0 | 2.1.0 | | [5.0.0-post](../../../tree/5.0.0-post/) | 5.0.0 | 2.0.0 | | [4.1.0-post](../../../tree/4.1.0-post/) | 4.1.0 | 1.1.0 | | [4.0.0-post](../../../tree/4.4.0-post/) | 4.0.0 | 1.0.0 | | [3.3.0-post](../../../tree/3.3.0-post/) | 3.3.0 | 0.11.0 | \*You must manually build the `2.3` version of Apache Kafka and the `5.3.x` version of Confluent Platform.

TeamNewPipe/NewPipeExtractor

NewPipe's core library for extracting data from streaming sites

bandcamp crawler extractor mediaccc newpipe peertube scraper soundcloud youtube

# NewPipe Extractor [](https://github.com/TeamNewPipe/NewPipeExtractor/actions/workflows/ci.yml) [](https://jitpack.io/#TeamNewPipe/NewPipeExtractor) [JDoc](https://teamnewpipe.github.io/NewPipeExtractor/javadoc/) • [Documentation](https://teamnewpipe.github.io/documentation/) NewPipe Extractor is a library for extracting things from streaming sites. It is a core component of [NewPipe](https://github.com/TeamNewPipe/NewPipe), but could be used independently. ## Usage NewPipe Extractor is available at JitPack's Maven repo. If you're using Gradle, you could add NewPipe Extractor as a dependency with the following steps: 1. Add `maven { url 'https://jitpack.io' }` to the `repositories` in your `build.gradle`. 2. Add `implementation 'com.github.TeamNewPipe:NewPipeExtractor:INSERT_VERSION_HERE'` to the `dependencies` in your `build.gradle`. Replace `INSERT_VERSION_HERE` with the [latest release](https://github.com/TeamNewPipe/NewPipeExtractor/releases/latest). 3. If you are using tools to minimize your project, make sure to keep the files below, by e.g. adding the following lines to your proguard file: ``` ## Rules for NewPipeExtractor -keep class org.schabi.newpipe.extractor.timeago.patterns.** { *; } -keep class org.mozilla.javascript.** { *; } -keep class org.mozilla.classfile.ClassFileWriter -dontwarn org.mozilla.javascript.tools.** ``` **Note:** To use NewPipe Extractor in Android projects with a `minSdk` below 26, [API desugaring](https://developer.android.com/studio/write/java8-support#library-desugaring) is required. If the `minSdk` is below 19, the `desugar_jdk_libs_nio` artifact is required, which requires Android Gradle Plugin (AGP) version 7.4.0. ### Testing changes To test changes quickly you can build the library locally. A good approach would be to add something like the following to your `settings.gradle`: ```groovy includeBuild('../NewPipeExtractor') { dependencySubstitution { substitute module('com.github.TeamNewPipe:NewPipeExtractor') with project(':extractor') } } ``` Another approach would be to use the local Maven repository, here's a gist of how to use it: 1. Add `mavenLocal()` in your project `repositories` list (usually as the first entry to give priority above the others). 2. It's _recommended_ that you change the `version` of this library (e.g. `LOCAL_SNAPSHOT`). 3. Run gradle's `ìnstall` task to deploy this library to your local repository (using the wrapper, present in the root of this project: `./gradlew install`) 4. Change the dependency version used in your project to match the one you chose in step 2 (`implementation 'com.github.TeamNewPipe:NewPipeExtractor:LOCAL_SNAPSHOT'`) > Tip for Android Studio users: After you make changes and run the `install` task, use the menu option `File → "Sync with File System"` to refresh the library in your project. ## Supported sites The following sites are currently supported: - YouTube - SoundCloud - media.ccc.de - PeerTube (no P2P) - Bandcamp ## License [](https://www.gnu.org/licenses/gpl-3.0.en.html) NewPipe Extractor is Free Software: You can use, study share and improve it at your will.

This library will generate code for use with MyBatis. It will introspect a database table (or many tables) and will generate artifacts that can be used to access the table(s). This lessens the initial nuisance of setting up objects and configuration files to interact with database tables. MBG seeks to make a major impact on the large percentage of database operations that are simple CRUD (Create, Retrieve, Update, Delete). MBG can generate code in multiple styles (or "runtimes"). MBG can generate code for Java based projects, or for Kotlin based projects. ## Eclipse Update Site (Direct) ## https://jeffgbutler.github.io/mybatis-generator-update-site/ ## Eclipse Update Site (Marketplace) ## https://marketplace.eclipse.org/content/mybatis-generator

Run thousands of self-healing API tests within minutes with no coding effort!** - **Comprehensive**: tests are generated automatically based on a large number scenarios and cover **every** field and header - **Intelligent**: tests are generated based on data types and constraints; each Fuzzer has specific expectations depending on the scenario under test - **Highly Configurable**: high amount of customization: you can filter specific Fuzzers, HTTP response codes, HTTP methods, request paths, provide business context and a lot more - **Self-Healing**: as tests are generated, any OpenAPI spec change is picked up automatically - **Simple to Learn**: flat learning curve, with intuitive configuration and syntax - **Fast**: automatic process for write, run and report tests which covers thousands of scenarios within minutes <p align="center"></p> > Short on time? Check out the [1-minute Quick Start Guide](https://endava.github.io/cats/docs/intro)! # Overview By using a simple and minimal syntax, with a flat learning curve, CATS (**C**ontract **A**PI **T**esting and **S**ecurity) enables you to generate thousands of API tests within minutes with **no coding effort**. All tests are **generated, run and reported automatically** based on a pre-defined set of **100+ Fuzzers**. The Fuzzers cover a wide range of boundary testing and negative scenarios from fully random large Unicode values to well crafted, context dependant values based on the request data types and constraints. Even more, you can leverage the fact that CATS generates request payloads dynamically and write simple end-to-end functional tests. ## HTML Report <div align="center"> <img alt="CATS" width="100%" src="images/tests_result.png"/> </div> ## Command Line <div align="center"> <img alt="CATS" width="100%" src="images/run_result.png"/> </div> # Tutorials on how to use CATS This is a list of articles with step-by-step guides on how to use CATS: * [Testing the GitHub API with CATS](https://ludovicianul.github.io/2020/10/05/github-api-testing/) * [How to write self-healing functional tests with no coding effort](https://ludovicianul.github.io/2020/09/09/cats/) # Some bugs found by CATS - https://github.com/hashicorp/vault/issues/13274 | https://github.com/hashicorp/vault/issues/13273 - https://github.com/hashicorp/vault/issues/13225 | https://github.com/hashicorp/vault/issues/13232 - https://github.com/go-gitea/gitea/issues/19397 | https://github.com/go-gitea/gitea/issues/19398 - https://github.com/go-gitea/gitea/issues/19399 # Installation ## Homebrew ```shell > brew tap endava/tap > brew install cats ``` ## Manual CATS is bundled both as an executable JAR or a native binary. The native binaries do not need Java installed. After downloading your OS native binary, you can add it to PATH so that you can execute it as any other command line tool: ```shell sudo cp cats /usr/local/bin/cats ``` You can also get autocomplete by downloading the [cats_autocomplete](cats_autocomplete) script and do: ```shell source cats_autocomplete ``` To get persistent autocomplete, add the above line in `.zshrc` or `.bashrc`, but make sure you put the fully qualified path for the `cats_autocomplete` script. You can also check the `cats_autocomplete` source for alternative setup. There is no native binary for Windows, but you can use the uberjar version. This requires Java 17+ to be installed. You can run it as `java -jar cats.jar`. Head to the releases page to download the latest version: [https://github.com/Endava/cats/releases](https://github.com/Endava/cats/releases). ## Build from sources You can build CATS from sources on you local box. You need [Java 17+](https://sdkman.io/jdks). Maven is already bundled. > Before running the first build, please make sure you do a `./mvnw clean`. CATS uses a fork of [OKHttp](https://square.github.io/okhttp/) which will install locally under the `4.11.0-CATS` version, so don't worry about overriding the official versions. You can use the following Maven command to build the project as an uberjar: `./mvnw package -Dquarkus.package.type=uber-jar` You will end up with a `cats-runner.jar` in the `target` folder. You can run it wih `java -jar cats-runner.jar ...`. You can also build native images using a [GraalVM Java version](https://www.graalvm.org/). `./mvnw package -Pnative` ### Notes on Unit Tests You may see some `error` log messages while running the Unit Tests. Those are expected behaviour for testing the negative scenarios of the Fuzzers. ## Experimental: Maven dependency for programmatic use CATS doesn't have explicit support (yet) for programmatic use via JUnit or TestNG. You can however experiment with running the `CatsMain` class with the same arguments as you would run in the command line. You must add these 2 dependencies: ```xml <dependency> <groupId>com.squareup.okhttp3</groupId> <artifactId>okhttp</artifactId> <version>4.11.0</version> </dependency> <dependency> <groupId>com.endava</groupId> <artifactId>cats</artifactId> <version>9.0.3</version> </dependency> ``` > Please not that you also need to explicitly add the `okhttp` dependency. > CATS uses a fork of okhttp that is not published in Maven central. > When using CATS as a dependency, HTTP header fuzzers that prefix/suffix header values with spaces won't properly work. # Contributing Please refer to [CONTRIBUTING.md](CONTRIBUTING.md).

android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="10dp" app:hl_cornerRadius="30dp" app:hl_cornerRadius_leftTop="0dp" app:hl_layoutBackground="#F76C6C" app:hl_layoutBackground_true="#89F76C6C" app:hl_shapeMode="pressed"> <TextView android:layout_width="wrap_content" android:layout_height="36dp" android:gravity="center" android:paddingLeft="10dp" android:paddingRight="10dp" android:text="selector的pressed用法，请点击" android:textColor="#fff" /> </com.lihang.ShadowLayout> ``` <br/> * #### 四、图片 selector的简单使用 ```xml <com.lihang.ShadowLayout android:id="@+id/ShadowLayout_shape" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="10dp" app:hl_cornerRadius="18dp" app:hl_cornerRadius_rightTop="0dp" app:hl_layoutBackground="@mipmap/test_background_false" app:hl_layoutBackground_true="@mipmap/test_background_true"> <TextView android:layout_width="wrap_content" android:layout_height="36dp" android:gravity="center" android:paddingLeft="10dp" android:paddingRight="10dp" android:text="图片selector" android:textColor="#fff" /> </com.lihang.ShadowLayout> ``` 如果你觉得麻烦，你还可以这样 ```xml <com.lihang.ShadowLayout android:id="@+id/ShadowLayout_image" android:layout_width="50dp" android:layout_height="50dp" android:layout_gravity="center_horizontal" android:layout_marginTop="10dp" app:hl_layoutBackground="@mipmap/game_6_right" app:hl_layoutBackground_true="@mipmap/game_6_wrong" app:hl_shapeMode="pressed" /> ``` <br/> * #### 五、渐变色的简单使用 ```xml <com.lihang.ShadowLayout android:layout_width="wrap_content" android:layout_height="wrap_content" app:hl_cornerRadius="18dp" app:hl_startColor="#ff0000" app:hl_endColor="#0000ff" > <TextView android:layout_width="160dp" android:layout_height="40dp" android:gravity="center" android:text="渐变色" android:textColor="#fff" /> </com.lihang.ShadowLayout> ``` <br/> * #### 六、水波纹ripple的使用 ```xml <com.lihang.ShadowLayout android:layout_width="wrap_content" android:layout_height="wrap_content" app:hl_cornerRadius="18dp" app:hl_shadowColor="#2a000000" app:hl_shadowLimit="7dp" app:hl_layoutBackground="#fff" app:hl_layoutBackground_true="#ff0000" app:hl_shapeMode="ripple" > <TextView android:layout_width="160dp" android:layout_height="40dp" android:gravity="center" android:text="水波纹" /> </com.lihang.ShadowLayout> ``` <br/> * #### 七、绑定textView，伴随文案及颜色变化 ```xml <com.lihang.ShadowLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="20dp" app:hl_bindTextView="@+id/txt_press" app:hl_cornerRadius="18dp" app:hl_layoutBackground="#FF9800" app:hl_layoutBackground_true="#ff0000" app:hl_shapeMode="pressed" app:hl_textColor_true="#fff" app:hl_text="点我，press样式" app:hl_text_true="我改变了文案了" > <TextView android:id="@+id/txt_press" android:layout_width="wrap_content" android:layout_height="36dp" android:gravity="center" android:paddingLeft="10dp" android:paddingRight="10dp" android:text="点我，press样式" android:textColor="#000" /> </com.lihang.ShadowLayout> ``` <br/> * #### 八、单条虚线、hl_shapeMode:dashLine的使用（以长边为宽度，短边为虚线width。由此可知，如下例子：为横向虚线） ```xml <com.lihang.ShadowLayout android:id="@+id/ShadowLayout_line" android:layout_width="match_parent" android:layout_height="1dp" app:hl_strokeColor="#ff0000" app:hl_shapeMode="dashLine" app:hl_stroke_dashWidth="5dp" app:hl_stroke_dashGap="5dp" /> ``` <br/> * #### 九、剪裁各种难以搞定的圆角（如特殊视频圆角剪裁，注意任何view被ShadowLayout包裹都能剪裁） ``` 如下代码，剪裁视频播放器(注明2点) - app:hl_layoutBackground="@color/transparent" 取消shadowLayout默认背景白色改透明 - app:clickable="false" 取消shadowLayout的点击焦点（用于解决recyclerView里的点击冲突） ``` ```xml <com.lihang.ShadowLayout android:id="@+id/shadowlayout_Container" android:layout_width="match_parent" android:layout_height="@dimen/dp_259" app:hl_cornerRadius_leftTop="@dimen/dp_12" app:hl_cornerRadius_rightTop="@dimen/dp_12" app:hl_layoutBackground="@color/transparent" app:clickable="false" > <com.iccapp.module.common.widget.video.VideoView android:id="@+id/video_view" android:layout_width="match_parent" android:layout_height="match_parent" /> </com.lihang.ShadowLayout> ``` <br/> ##

Tsunami is a general purpose network security scanner with an extensible plugin system for detecting high severity vulnerabilities with high confidence.

# Tsunami  Tsunami is a general purpose network security scanner with an extensible plugin system for detecting high severity vulnerabilities with high confidence. To learn more about Tsunami, visit our [documentation](https://github.com/google/tsunami-security-scanner/blob/master/docs/index.md). Tsunami relies heavily on its plugin system to provide basic scanning capabilities. All publicly available Tsunami plugins are hosted in a separate [google/tsunami-security-scanner-plugins](https://github.com/google/tsunami-security-scanner-plugins) repository. ## Current Status * Currently Tsunami is in 'pre-alpha' release for developer preview. * Tsunami project is currently under active development. Do expect major API changes in the future. ## Quick Start To quickly get started with Tsunami scans, ### Traditional install 1. install the following required dependencies: ``` nmap >= 7.80 ncrack >= 0.7 ``` 1. start a vulnerable application that can be identified by Tsunami, e.g. an unauthenticated Jupyter Notebook server. The easiest way is to use a docker image: ```shell docker run --name unauthenticated-jupyter-notebook -p 8888:8888 -d jupyter/base-notebook start-notebook.sh --NotebookApp.token='' ``` 1. execute the following command: ``` bash -c "$(curl -sfL https://raw.githubusercontent.com/google/tsunami-security-scanner/master/quick_start.sh)" ``` The `quick_start.sh` script performs the following tasks: 1. Clone the [google/tsunami-security-scanner](https://github.com/google/tsunami-security-scanner) and [google/tsunami-security-scanner-plugins](https://github.com/google/tsunami-security-scanner-plugins) repos into `$HOME/tsunami/repos` directory. 1. Compile all [Google Tsunami plugins](https://github.com/google/tsunami-security-scanner-plugins/tree/master/google) and move all plugin `jar` files into `$HOME/tsunami/plugins` directory. 1. Compile the Tsunami scanner Fat Jar file and move it into `$HOME/tsunami` directory. 1. Move the `tsunami.yaml` example config into `$HOME/tsunami` directory. 1. Print example Tsunami command for scanning `127.0.0.1` using the previously generated artifacts. ### Docker install 1. start a vulnerable application that can be identified by Tsunami, e.g. an unauthenticated Jupyter Notebook server. The easiest way is to use a docker image: ```shell docker run --name unauthenticated-jupyter-notebook -p 8888:8888 -d jupyter/base-notebook start-notebook.sh --NotebookApp.token='' ``` 1. build the docker image for Tsunami: ```shell docker build -t tsunami . ``` 1. run the Tsunami image. The logs can be saved to the host machine by mounting a volume: ```shell docker run --network="host" -v "$(pwd)/logs":/usr/tsunami/logs tsunami ``` 1. debugging issues with Tsunami container. The tsunami container is based on Debian. To run debug tools simply exec into the container and install them: ```shell docker exec -it tsunami bash ``` ## Contributing Read how to [contribute to Tsunami](docs/contributing.md). ## License Tsunami is released under the [Apache 2.0 license](LICENSE). ``` Copyright 2019 Google Inc.

alibaba/QLExpress

QLExpress is a powerful, lightweight, dynamic language for the Java platform aimed at improving developers’ productivity in different business scenes.

# QLExpress基本语法 [](https://gitter.im/QLExpress/Lobby?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) # 一、背景介绍 由阿里的电商业务规则、表达式（布尔组合）、特殊数学公式计算（高精度）、语法分析、脚本二次定制等强需求而设计的一门动态脚本引擎解析工具。 在阿里集团有很强的影响力，同时为了自身不断优化、发扬开源贡献精神，于2012年开源。 QLExpress脚本引擎被广泛应用在阿里的电商业务场景，具有以下的一些特性: - 1、线程安全，引擎运算过程中的产生的临时变量都是threadlocal类型。 - 2、高效执行，比较耗时的脚本编译过程可以缓存在本地机器，运行时的临时变量创建采用了缓冲池的技术，和groovy性能相当。 - 3、弱类型脚本语言，和groovy，javascript语法类似，虽然比强类型脚本语言要慢一些，但是使业务的灵活度大大增强。 - 4、安全控制,可以通过设置相关运行参数，预防死循环、高危系统api调用等情况。 - 5、代码精简，依赖最小，250k的jar包适合所有java的运行环境，在android系统的低端pos机也得到广泛运用。 # 二、依赖和调用说明 ```xml <dependency> <groupId>com.alibaba</groupId> <artifactId>QLExpress</artifactId> <version>3.3.3</version> </dependency> ``` 版本兼容性: [跳转查看](VERSIONS.md) ```java ExpressRunner runner = new ExpressRunner(); DefaultContext<String, Object> context = new DefaultContext<String, Object>(); context.put("a", 1); context.put("b", 2); context.put("c", 3); String express = "a + b * c"; Object r = runner.execute(express, context, null, true, false); System.out.println(r); ``` 如果应用有让终端用户输入与执行 QLExpress 的功能，务必关注 [多级别安全控制](#4-多级别安全控制)，**将 QLExpress 的安全级别配置在白名单或以上。** # 三、语法介绍 ## 1、操作符和java对象操作 ### 普通java语法 ```java //支持 +,-,*,/,<,>,<=,>=,==,!=,<>【等同于!=】,%,mod【取模等同于%】,++,--, //in【类似sql】,like【sql语法】,&&,||,!,等操作符 //支持for，break、continue、if then else 等标准的程序控制逻辑 n = 10; sum = 0; for(i = 0; i < n; i++) { sum = sum + i; } return sum; //逻辑三元操作 a = 1; b = 2; maxnum = a > b ? a : b; ``` ### 和java语法相比，要避免的一些ql写法错误 - 不支持try{}catch{} - 注释目前只支持 /** **/，不支持单行注释 // - 不支持java8的lambda表达式 - 不支持for循环集合操作for (Item item : list) - 弱类型语言，请不要定义类型声明,更不要用Template（Map<String, List>之类的） - array的声明不一样 - min,max,round,print,println,like,in 都是系统默认函数的关键字，请不要作为变量名 ``` //java语法：使用泛型来提醒开发者检查类型 keys = new ArrayList<String>(); deviceName2Value = new HashMap<String, String>(7); String[] deviceNames = {"ng", "si", "umid", "ut", "mac", "imsi", "imei"}; int[] mins = {5, 30}; //ql写法： keys = new ArrayList(); deviceName2Value = new HashMap(); deviceNames = ["ng", "si", "umid", "ut", "mac", "imsi", "imei"]; mins = [5, 30]; //java语法：对象类型声明 FocFulfillDecisionReqDTO reqDTO = param.getReqDTO(); //ql写法： reqDTO = param.getReqDTO(); //java语法：数组遍历 for(Item item : list) { } //ql写法： for(i = 0; i < list.size(); i++){ item = list.get(i); } //java语法：map遍历 for(String key : map.keySet()) { System.out.println(map.get(key)); } //ql写法： keySet = map.keySet(); objArr = keySet.toArray(); for (i = 0; i < objArr.length; i++) { key = objArr[i]; System.out.println(map.get(key)); } ``` ### java的对象操作 ```java import com.ql.util.express.test.OrderQuery; //系统自动会import java.lang.*,import java.util.*; query = new OrderQuery(); // 创建class实例，自动补全类路径 query.setCreateDate(new Date()); // 设置属性 query.buyer = "张三"; // 调用属性，默认会转化为setBuyer("张三") result = bizOrderDAO.query(query); // 调用bean对象的方法 System.out.println(result.getId()); // 调用静态方法 ``` ## 2、脚本中定义function ```java function add(int a, int b){ return a + b; }; function sub(int a, int b){ return a - b; }; a = 10; return add(a, 4) + sub(a, 9); ``` ## 3、扩展操作符：Operator ### 替换 if then else 等关键字 ```java runner.addOperatorWithAlias("如果", "if", null); runner.addOperatorWithAlias("则", "then", null); runner.addOperatorWithAlias("否则", "else", null); express = "如果 (语文 + 数学 + 英语 > 270) 则 {return 1;} 否则 {return 0;}"; DefaultContext<String, Object> context = new DefaultContext<String, Object>(); runner.execute(express, context, null, false, false, null); ``` ### 如何自定义Operator ```java import java.util.ArrayList; import java.util.List; /** * 定义一个继承自com.ql.util.express.Operator的操作符 */ public class JoinOperator extends Operator { public Object executeInner(Object[] list) throws Exception { Object opdata1 = list[0]; Object opdata2 = list[1]; if (opdata1 instanceof List) { ((List)opdata1).add(opdata2); return opdata1; } else { List result = new ArrayList(); for (Object opdata : list) { result.add(opdata); } return result; } } } ``` ### 如何使用Operator ```java //(1)addOperator ExpressRunner runner = new ExpressRunner(); DefaultContext<String, Object> context = new DefaultContext<String, Object>(); runner.addOperator("join", new JoinOperator()); Object r = runner.execute("1 join 2 join 3", context, null, false, false); System.out.println(r); // 返回结果 [1, 2, 3] //(2)replaceOperator ExpressRunner runner = new ExpressRunner(); DefaultContext<String, Object> context = new DefaultContext<String, Object>(); runner.replaceOperator("+", new JoinOperator()); Object r = runner.execute("1 + 2 + 3", context, null, false, false); System.out.println(r); // 返回结果 [1, 2, 3] //(3)addFunction ExpressRunner runner = new ExpressRunner(); DefaultContext<String, Object> context = new DefaultContext<String, Object>(); runner.addFunction("join", new JoinOperator()); Object r = runner.execute("join(1, 2, 3)", context, null, false, false); System.out.println(r); // 返回结果 [1, 2, 3] ``` ## 4、绑定java类或者对象的method addFunctionOfClassMethod + addFunctionOfServiceMethod ```java public class BeanExample { public static String upper(String abc) { return abc.toUpperCase(); } public boolean anyContains(String str, String searchStr) { char[] s = str.toCharArray(); for (char c : s) { if (searchStr.contains(c+"")) { return true; } } return false; } } runner.addFunctionOfClassMethod("取绝对值", Math.class.getName(), "abs", new String[] {"double"}, null); runner.addFunctionOfClassMethod("转换为大写", BeanExample.class.getName(), "upper", new String[] {"String"}, null); runner.addFunctionOfServiceMethod("打印", System.out, "println", new String[] { "String" }, null); runner.addFunctionOfServiceMethod("contains", new BeanExample(), "anyContains", new Class[] {String.class, String.class}, null); String express = "取绝对值(-100); 转换为大写(\"hello world\"); 打印(\"你好吗？\"); contains("helloworld",\"aeiou\")"; runner.execute(express, context, null, false, false); ``` ## 5、macro 宏定义 ```java runner.addMacro("计算平均成绩", "(语文+数学+英语)/3.0"); runner.addMacro("是否优秀", "计算平均成绩>90"); IExpressContext<String, Object> context = new DefaultContext<String, Object>(); context.put("语文", 88); context.put("数学", 99); context.put("英语", 95); Object result = runner.execute("是否优秀", context, null, false, false); System.out.println(r); //返回结果true ``` ## 6、编译脚本，查询外部需要定义的变量和函数。 **注意以下脚本int和没有int的区别** ```java String express = "int 平均分 = (语文 + 数学 + 英语 + 综合考试.科目2) / 4.0; return 平均分"; ExpressRunner runner = new ExpressRunner(true, true); String[] names = runner.getOutVarNames(express); for(String s:names){ System.out.println("var : " + s); } //输出结果： var : 数学 var : 综合考试 var : 英语 var : 语文 ``` ## 7、关于不定参数的使用 ```java @Test public void testMethodReplace() throws Exception { ExpressRunner runner = new ExpressRunner(); IExpressContext<String, Object> expressContext = new DefaultContext<String, Object>(); runner.addFunctionOfServiceMethod("getTemplate", this, "getTemplate", new Class[]{Object[].class}, null); //(1)默认的不定参数可以使用数组来代替 Object r = runner.execute("getTemplate([11,'22', 33L, true])", expressContext, null, false, false); System.out.println(r); //(2)像java一样,支持函数动态参数调用,需要打开以下全局开关,否则以下调用会失败 DynamicParamsUtil.supportDynamicParams = true; r = runner.execute("getTemplate(11, '22', 33L, true)", expressContext, null, false, false); System.out.println(r); } //等价于getTemplate(Object[] params) public Object getTemplate(Object... params) throws Exception{ String result = ""; for(Object obj:params){ result = result + obj + ","; } return result; } ``` ## 8、关于集合的快捷写法 ```java @Test public void testSet() throws Exception { ExpressRunner runner = new ExpressRunner(false, false); DefaultContext<String, Object> context = new DefaultContext<String, Object>(); String express = "abc = NewMap(1:1, 2:2); return abc.get(1) + abc.get(2);"; Object r = runner.execute(express, context, null, false, false); System.out.println(r); express = "abc = NewList(1, 2, 3); return abc.get(1) + abc.get(2)"; r = runner.execute(express, context, null, false, false); System.out.println(r); express = "abc = [1, 2, 3]; return abc[1] + abc[2];"; r = runner.execute(express, context, null, false, false); System.out.println(r); } ``` ## 9、集合的遍历 其实类似java的语法，只是ql不支持for(obj:list){}的语法，只能通过下标访问。 ```java //遍历map map = new HashMap(); map.put("a", "a_value"); map.put("b", "b_value"); keySet = map.keySet(); objArr = keySet.toArray(); for (i = 0; i < objArr.length; i++) { key = objArr[i]; System.out.println(map.get(key)); } ``` # 四、运行参数和API列表介绍 QLExpressRunner如下图所示，从语法树分析、上下文、执行过程三个方面提供二次定制的功能扩展。  ## 1、属性开关 ### isPrecise ```java /** * 是否需要高精度计算 */ private boolean isPrecise = false; ``` > 高精度计算在会计财务中非常重要，java的float、double、int、long存在很多隐式转换，做四则运算和比较的时候其实存在非常多的安全隐患。 > 所以类似汇金的系统中，会有很多BigDecimal转换代码。而使用QLExpress，你只要关注数学公式本身 _订单总价 = 单价 * 数量 + 首重价格 + （ 总重量 - 首重） * 续重单价_ ，然后设置这个属性即可，所有的中间运算过程都会保证不丢失精度。 ### isShortCircuit ```java /** * 是否使用逻辑短路特性 */ private boolean isShortCircuit = true; ``` 在很多业务决策系统中，往往需要对布尔条件表达式进行分析输出，普通的java运算一般会通过逻辑短路来减少性能的消耗。例如规则公式： _star > 10000 and shopType in ('tmall', 'juhuasuan') and price between (100, 900)_ 假设第一个条件 _star>10000_ 不满足就停止运算。但业务系统却还是希望把后面的逻辑都能够运算一遍，并且输出中间过程，保证更快更好的做出决策。 参照单元测试:[ShortCircuitLogicTest.java](https://github.com/alibaba/QLExpress/blob/master/src/test/java/com/ql/util/express/test/logic/ShortCircuitLogicTest.java) ### isTrace ```java /** * 是否输出所有的跟踪信息，同时还需要log级别是DEBUG级别 */ private boolean isTrace = false; ``` 这个主要是是否输出脚本的编译解析过程，一般对于业务系统来说关闭之后会提高性能。 ## 2、调用入参 ```java /** * 执行一段文本 * @param expressString 程序文本 * @param context 执行上下文，可以扩展为包含ApplicationContext * @param errorList 输出的错误信息List * @param isCache 是否使用Cache中的指令集,建议为true * @param isTrace 是否输出详细的执行指令信息，建议为false * @param aLog 输出的log * @return * @throws Exception */ Object execute(String expressString, IExpressContext<String, Object> context, List<String> errorList, boolean isCache, boolean isTrace); ``` ## 3、功能扩展API列表 QLExpress主要通过子类实现Operator.java提供的以下方法来最简单的操作符定义，然后可以被通过addFunction或者addOperator的方式注入到ExpressRunner中。 ```java public abstract Object executeInner(Object[] list) throws Exception; ``` 比如我们几行代码就可以实现一个功能超级强大、非常好用的join操作符: ``` _list = 1 join 2 join 3;_ -> [1,2,3] _list = join(list, 4, 5, 6);_ -> [1,2,3,4,5,6] ``` ```java import java.util.ArrayList; import java.util.List; public class JoinOperator extends Operator { public Object executeInner(Object[] list) throws Exception { List result = new ArrayList(); Object opdata1 = list[0]; if (opdata1 instanceof List) { result.addAll((List)opdata1); } else { result.add(opdata1); } for (int i = 1; i < list.length; i++) { result.add(list[i]); } return result; } } ``` 如果你使用Operator的基类OperatorBase.java将获得更强大的能力，基本能够满足所有的要求。 ### （1）function相关API ```java //通过name获取function的定义 OperatorBase getFunciton(String name); //通过自定义的Operator来实现类似：fun(a, b, c) void addFunction(String name, OperatorBase op); //fun(a, b, c) 绑定 object.function(a, b, c)对象方法 void addFunctionOfServiceMethod(String name, Object aServiceObject, String aFunctionName, Class<?>[] aParameterClassTypes, String errorInfo); //fun(a, b, c) 绑定 Class.function(a, b, c)类方法 void addFunctionOfClassMethod(String name, String aClassName, String aFunctionName, Class<?>[] aParameterClassTypes, String errorInfo); //给Class增加或者替换method，同时支持 a.fun(b), fun(a, b) 两种方法调用 //比如扩展String.class的isBlank方法:"abc".isBlank()和isBlank("abc")都可以调用 void addFunctionAndClassMethod(String name, Class<?> bindingClass, OperatorBase op); ``` ### （2）Operator相关API 提到脚本语言的操作符，优先级、运算的目数、覆盖原始的操作符(+,-,*,/等等)都是需要考虑的问题，QLExpress统统帮你搞定了。 ```java //添加操作符号,可以设置优先级 void addOperator(String name, Operator op); void addOperator(String name, String aRefOpername, Operator op); //替换操作符处理 OperatorBase replaceOperator(String name, OperatorBase op); //添加操作符和关键字的别名，比如 if..then..else -> 如果。。那么。。否则。。 void addOperatorWithAlias(String keyWordName, String realKeyWordName, String errorInfo); ``` ### （3）宏定义相关API QLExpress的宏定义比较简单，就是简单的用一个变量替换一段文本，和传统的函数替换有所区别。 ```java //比如addMacro("天猫卖家", "userDO.userTag &1024 == 1024") void addMacro(String macroName, String express); ``` ### （4）java class的相关api QLExpress可以通过给java类增加或者改写一些method和field，比如 链式调用："list.join("1").join("2")"，比如中文属性："list.长度"。 ```java //添加类的属性字段 void addClassField(String field, Class<?>bindingClass, Class<?>returnType, Operator op); //添加类的方法 void addClassMethod(String name, Class<?>bindingClass, OperatorBase op); ``` > 注意，这些类的字段和方法是执行器通过解析语法执行的，而不是通过字节码增强等技术，所以只在脚本运行期间生效，不会对jvm整体的运行产生任何影响，所以是绝对安全的。 ### （4）语法树解析变量、函数的API > 这些接口主要是对一个脚本内容的静态分析，可以作为上下文创建的依据，也可以用于系统的业务处理。 > 比如：计算 "a + fun1(a) + fun2(a + b) + c.getName()" > 包含的变量:a,b,c > 包含的函数:fun1,fun2 ```java //获取一个表达式需要的外部变量名称列表 String[] getOutVarNames(String express); String[] getOutFunctionNames(String express); ``` ### （5）语法解析校验api 脚本语法是否正确，可以通过ExpressRunner编译指令集的接口来完成。 ```java String expressString = "for(i = 0; i < 10; i++) {sum = i + 1;} return sum;"; InstructionSet instructionSet = expressRunner.parseInstructionSet(expressString); //如果调用过程不出现异常，指令集instructionSet就是可以被加载运行（execute）了！ ``` ### （6）指令集缓存相关的api 因为QLExpress对文本到指令集做了一个本地HashMap缓存，通常情况下一个设计合理的应用脚本数量应该是有限的，缓存是安全稳定的，但是也提供了一些接口进行管理。 ```java //优先从本地指令集缓存获取指令集，没有的话生成并且缓存在本地 InstructionSet getInstructionSetFromLocalCache(String expressString); //清除缓存 void clearExpressCache(); ``` ### （7）安全风险控制 #### 7.1 防止死循环 ```java try { express = "sum = 0; for(i = 0; i < 1000000000; i++) {sum = sum + i;} return sum;"; //可通过timeoutMillis参数设置脚本的运行超时时间:1000ms Object r = runner.execute(express, context, null, true, false, 1000); System.out.println(r); throw new Exception("没有捕获到超时异常"); } catch (QLTimeOutException e) { System.out.println(e); } ``` #### 7.1 防止调用不安全的系统api 更加详细多级安全控制见 [多级别安全控制](#4-多级别安全控制) ```java ExpressRunner runner = new ExpressRunner(); QLExpressRunStrategy.setForbiddenInvokeSecurityRiskMethods(true); DefaultContext<String, Object> context = new DefaultContext<String, Object>(); try { express = "System.exit(1);"; Object r = runner.execute(express, context, null, true, false); System.out.println(r); throw new Exception("没有捕获到不安全的方法"); } catch (QLException e) { System.out.println(e); } ``` ### （8）增强上下文参数Context相关的api #### 8.1 与spring框架的无缝集成 上下文参数 IExpressContext context 非常有用，它允许put任何变量，然后在脚本中识别出来。 在实际中我们很希望能够无缝的集成到spring框架中，可以仿照下面的例子使用一个子类。 ```java public class QLExpressContext extends HashMap<String, Object> implements IExpressContext<String, Object> { private final ApplicationContext context; // 构造函数，传入context 和 ApplicationContext public QLExpressContext(Map<String, Object> map, ApplicationContext aContext) { super(map); this.context = aContext; } /** * 抽象方法：根据名称从属性列表中提取属性值 */ public Object get(Object name) { Object result; result = super.get(name); try { if (result == null && this.context != null && this.context.containsBean((String)name)) { // 如果在Spring容器中包含bean，则返回String的Bean result = this.context.getBean((String)name); } } catch (Exception e) { throw new RuntimeException(e); } return result; } public Object put(String name, Object object) { return super.put(name, object); } } ``` 完整的demo参照 [SpringDemoTest.java](https://github.com/alibaba/QLExpress/blob/master/src/test/java/com/ql/util/express/test/spring/SpringDemoTest.java) #### 8.2 自定义函数操作符获取原始的context控制上下文 自定义的Operator需要直接继承OperatorBase，获取到parent即可，可以用于在运行一组脚本的时候，直接编辑上下文信息，业务逻辑处理上也非常有用。 ```java public class ContextMessagePutTest { class OperatorContextPut extends OperatorBase { public OperatorContextPut(String aName) { this.name = aName; } @Override public OperateData executeInner(InstructionSetContext parent, ArraySwap list) throws Exception { String key = list.get(0).toString(); Object value = list.get(1); parent.put(key, value); return null; } } @Test public void test() throws Exception { ExpressRunner runner = new ExpressRunner(); OperatorBase op = new OperatorContextPut("contextPut"); runner.addFunction("contextPut", op); String express = "contextPut('success', 'false'); contextPut('error', '错误信息'); contextPut('warning', '提醒信息')"; IExpressContext<String, Object> context = new DefaultContext<String, Object>(); context.put("success", "true"); Object result = runner.execute(express, context, null, false, true); System.out.println(result); System.out.println(context); } } ``` ## 4. 多级别安全控制 QLExpress 与本地 JVM 交互的方式有： - 应用中的自定义函数/操作符/宏: 该部分不在 QLExpress 运行时的管控范围，属于应用开放给脚本的业务功能，不受安全控制，应用需要自行确保这部分是安全的 - 在 QLExpress 运行时中发生的交互: 安全控制可以对这一部分进行管理, QLExpress 会开放相关的配置给应用 - 通过 `.` 操作符获取 Java 对象的属性或者调用 Java 对象中的方法 - 通过 `import` 可以导入 JVM 中存在的任何类并且使用, 默认情况下会导入 `java.lang`, `java.util` 以及 `java.util.stream` 在不同的场景下，应用可以配置不同的安全级别，安全级别由低到高： 1. 黑名单控制：QLExpress 默认会阻断一些高危的系统 API, 用户也可以自行添加, 但是开放对 JVM 中其他所有类与方法的访问, 最灵活, 但是很容易被反射工具类绕过，只适用于脚本安全性有其他严格控制的场景，禁止直接运行终端用户输入 2. 白名单控制：QLExpress 支持编译时白名单和运行时白名单机制, 编译时白名单设置到类级别, 能够在语法检查阶段就暴露出不安全类的使用, 但是无法阻断运行时动态生成的类(比如通过反射), 运行时白名单能够确保运行时只可以直接调用有限的 Java 方法, 必须设置了运行时白名单, 才算是达到了这个级别 3. 沙箱模式：QLExpress 作为一个语言沙箱, 只允许通过自定义函数/操作符/宏与应用交互, 不允许与 JVM 中的类产生交互 ### （1） 黑名单控制 QLExpess 目前默认添加的黑名单有： - `java.lang.System.exit` - `java.lang.Runtime.exec` - `java.lang.ProcessBuilder.start` - `java.lang.reflect.Method.invoke` - `java.lang.reflect.Class.forName` - `java.lang.reflect.ClassLoader.loadClass` - `java.lang.reflect.ClassLoader.findClass` 同时支持通过 `QLExpressRunStrategy.addSecurityRiskMethod` 额外添加 `com.ql.util.express.example.MultiLevelSecurityTest#blockWhiteListControlTest` ```java // 必须将该选项设置为 true QLExpressRunStrategy.setForbidInvokeSecurityRiskMethods(true); // 这里不区分静态方法与成员方法, 写法一致 // 不支持重载, riskMethod 的所有重载方法都会被禁止 QLExpressRunStrategy.addSecurityRiskMethod(RiskBean.class, "riskMethod"); ExpressRunner expressRunner = new ExpressRunner(); DefaultContext<String, Object> context = new DefaultContext<>(); try { expressRunner.execute("import com.ql.util.express.example.RiskBean;" + "RiskBean.riskMethod()", context, null, true, false); fail("没有捕获到不安全的方法"); } catch (Exception e) { assertTrue(e.getCause() instanceof QLSecurityRiskException); } ``` ### （2）白名单控制 **编译期白名单：** 编译期白名单是类维度的，脚本中只允许显式引用符合白名单条件的类，支持两种设置方式，精确设置某个类，以及设置某个类的全部子类。 `com.ql.util.express.example.MultiLevelSecurityTest#compileWhiteListTest` ```java // 设置编译期白名单 QLExpressRunStrategy.setCompileWhiteCheckerList(Arrays.asList( // 精确设置 CheckerFactory.must(Date.class), // 子类设置 CheckerFactory.assignable(List.class) )); ExpressRunner expressRunner = new ExpressRunner(); // Date 在编译期白名单中, 可以显示引用 expressRunner.execute("new Date()", new DefaultContext<>(), null, false, true); // LinkedList 是 List 的子类, 符合白名单要求 expressRunner.execute("LinkedList ll = new LinkedList; ll.add(1); ll.add(2); ll", new DefaultContext<>(), null, false, true); try { // String 不在白名单中, 不可以显示引用 // 但是隐式引用, a = 'mmm', 或者定义字符串常量 'mmm' 都是可以的 expressRunner.execute("String a = 'mmm'", new DefaultContext<>(), null, false, true); } catch (Exception e) { assertTrue(e.getCause() instanceof QLSecurityRiskException); } // Math 不在白名单中 // 对于不满足编译期类型白名单的脚本无需运行, 即可通过 checkSyntax 检测出 assertFalse(expressRunner.checkSyntax("Math.abs(-1)")); ``` 编译期白名单只能检测出脚本编译时能够确认的类型，任何运行时出现的类型都是无法检测的，诸如各种反射`Class.forName`, `ClassLoader.loadClass`，或者没有声明类型的变量等等，因为编译期白名单只能增加黑客的作案成本，是容易被绕过。因此建议编译期白名单只用来帮助脚本校验，如果需要接收终端用户输入，运行期白名单是务必要配置的。 **运行期白名单：** 如果有白名单设置，所有的黑名单设置就都会无效，以白名单为准。默认没有白名单设置。 `com.ql.util.express.example.MultiLevelSecurityTest#blockWhiteListControlTest` ```java // 必须将该选项设置为 true QLExpressRunStrategy.setForbidInvokeSecurityRiskMethods(true); // 有白名单设置时, 则黑名单失效 QLExpressRunStrategy.addSecureMethod(RiskBean.class, "secureMethod"); // 白名单中的方法, 允许正常调用 expressRunner.execute("import com.ql.util.express.example.RiskBean;" + "RiskBean.secureMethod()", context, null, true, false); try { // java.lang.String.length 不在白名单中, 不允许调用 expressRunner.execute("'abcd'.length()", context, null, true, false); fail("没有捕获到不安全的方法"); } catch (Exception e) { assertTrue(e.getCause() instanceof QLSecurityRiskException); } // setSecureMethods 设置方式 Set<String> secureMethods = new HashSet<>(); secureMethods.add("java.lang.String.length"); secureMethods.add("java.lang.Integer.valueOf"); QLExpressRunStrategy.setSecureMethods(secureMethods); // 白名单中的方法, 允许正常调用 Object res = expressRunner.execute("Integer.valueOf('abcd'.length())", context, null, true, false); assertEquals(4, res); try { // java.lang.Long.valueOf 不在白名单中, 不允许调用 expressRunner.execute("Long.valueOf('abcd'.length())", context, null, true, false); fail("没有捕获到不安全的方法"); } catch (Exception e) { assertTrue(e.getCause() instanceof QLSecurityRiskException); } ``` 从上图中可以看出白名单有两种设置方式： - 添加：`QLExpressRunStrategy.addSecureMethod` - 置换：`QLExpressRunStrategy.setSecureMethods` 在应用中使用的时，推荐将白名单配置在诸如 `etcd`,`configServer` 等配置服务中，根据需求随时调整。 ### （3）沙箱模式 如果你厌烦上述复杂的配置，只是想完全关闭 QLExpress 和 Java 应用的自由交互，那么推荐使用沙箱模式。 在沙箱模式中，脚本**不可以**： - import Java 类 - 显式引用 Java 类，比如 `String a = 'mmm'` - 取 Java 类中的字段：`a = new Integer(11); a.value` - 调用 Java 类中的方法：`Math.abs(12)` 脚本**可以**： - 使用 QLExpress 的自定义操作符/宏/函数，以此实现与应用的受控交互 - 使用 `.` 操作符获取 `Map` 的 `key` 对应的 `value`，比如 `a` 在应用传入的表达式中是一个 `Map`，那么可以通过 `a.b` 获取 - 所有不涉及应用 Java 类的操作 `com.ql.util.express.example.MultiLevelSecurityTest#sandboxModeTest` ```java // 开启沙箱模式 QLExpressRunStrategy.setSandBoxMode(true); ExpressRunner expressRunner = new ExpressRunner(); // 沙箱模式下不支持 import 语句 assertFalse(expressRunner.checkSyntax("import com.ql.util.express.example.RiskBean;")); // 沙箱模式下不支持显式的类型引用 assertFalse(expressRunner.checkSyntax("String a = 'abc'")); assertTrue(expressRunner.checkSyntax("a = 'abc'")); // 无法用 . 获取 Java 类属性或者 Java 类方法 try { expressRunner.execute("'abc'.length()", new DefaultContext<>(), null, false, true); fail(); } catch (QLException e) { // 没有找到方法:length } try { DefaultContext<String, Object> context = new DefaultContext<>(); context.put("test", new CustBean(12)); expressRunner.execute("test.id", context, null, false, true); fail(); } catch (RuntimeException e) { // 无法获取属性:id } // 沙箱模式下可以使用 自定义操作符/宏/函数 和应用进行交互 expressRunner.addFunction("add", new Operator() { @Override public Object executeInner(Object[] list) throws Exception { return (Integer) list[0] + (Integer) list[1]; } }); assertEquals(3, expressRunner.execute("add(1,2)", new DefaultContext<>(), null, false, true)); // 可以用 . 获取 map 的属性 DefaultContext<String, Object> context = new DefaultContext<>(); HashMap<Object, Object> testMap = new HashMap<>(); testMap.put("a", "t"); context.put("test", testMap); assertEquals("t", expressRunner.execute("test.a", context, null, false, true)); ``` 在沙箱模式下，为了进一步保障内存的安全，建议同时限制脚本能够申请的最大数组长度以及超时时间，设置方法如下： `com.ql.util.express.test.ArrayLenCheckTest` ```java // 限制最大申请数组长度为10, 默认没有限制 QLExpressRunStrategy.setMaxArrLength(10); ExpressRunner runner = new ExpressRunner(); String code = "byte[] a = new byte[11];"; try { // 20ms 超时时间 runner.execute(code, new DefaultContext<>(), null, false, false, 20); Assert.fail(); } catch (QLException e) { } QLExpressRunStrategy.setMaxArrLength(-1); // 20ms 超时时间 runner.execute(code, new DefaultContext<>(), null, false, false, 20); ``` 附录： [版本更新列表](VERSIONS.md) ## links for us - Gitter channel - Online chat room with QLExpress developers.

<p align="center"> <a target="_blank" href="http://www.wgstart.com"> <img src="./demo/logo.png"> </a> </p> ## WGCLOUD [中文版README](./README_cn.md) Wgcloud design idea is a new generation of very simple operation and maintenance monitoring system, which advocates rapid deployment, reduces the difficulty of operation and maintenance learning, runs automatically, and has no template and script. **The current warehouse version is v2 3.7 for the latest secondary development, please pull the master branch.** Wgcloud is developed based on the microservice springboot architecture, and is a lightweight and high-performance distributed monitoring system. The core collection indexes include: **CPU utilization, CPU temperature, memory utilization, disk capacity, disk IO, smart health status of hard disk, system load, number of connections, network card traffic, hardware system information, etc. Support the monitoring of process applications, files, ports, logs, docker containers, databases, data tables and other resources on the server. Support monitoring service interface API, data communication equipment (such as switch, router, printer), etc. Automatically generate network topology map, large screen visualization, web SSH (Fortress machine), statistical analysis chart, command issuance, batch execution, alarm information push (such as email, nail, wechat, SMS, etc.)** 1. V2.3.7 abandons the sigar method of v2.3.6 to obtain host indicators, and v2.3.7 uses popular oshi components to collect host indicators 2. the server and client work together, which is lighter and more efficient, and can support thousands of hosts to monitor online at the same time. 3. The server side is responsible for receiving data, processing data, and generating chart display. The agent side reports the index data every 30 seconds (time adjustable) by default. 4. support the installation and deployment of mainstream server platforms, such as Linux, windows, MacOS, etc. 5. Wgcloud adopts springboot+bootstrap to realize the distributed monitoring system perfectly, which is used to feed the open source community and open source for the second time. 6. if you feel wggroup has helped you, you don't need to reward it, just click star to support it 7.

yanzhenjie/SwipeRecyclerView

:melon: RecyclerView侧滑菜单，Item拖拽，滑动删除Item，自动加载更多，HeaderView，FooterView，Item分组黏贴。

footerview headerview item-drag loadmore recyclerview swipe-delete swipe-menu

# SwipeRecyclerView 作者的主页：[https://www.yanzhenjie.com](https://www.yanzhenjie.com) 技术交流群：[46505645](https://jq.qq.com/?_wv=1027&k=5wY8UWl) ---- 本库是基于RecyclerView的封装，提供了Item侧滑菜单、Item滑动删除、Item长按拖拽、添加HeaderView/FooterView、加载更多、Item点击监听等基本功能。 ## 特性 1. Item侧滑菜单，支持水平分布、垂直分布 2. Item长按拖拽、侧滑删除 3. 添加/移除HeaderView/FooterView 4. **自动/点击**加载更多的功能 5. 支持二级列表，List形式、Grid形式、Staggered形式 6. Sticky普通布局黏贴和ReyclerView分组黏贴 7. 支持AndroidX > 使用本库只需要使用SwipeRecyclerView即可，用法和原生RecyclerView一模一样，本库比原生的RecyclerView多了几个扩展方法。 ## 截图 对上面提到的效果基本都有演示，但不是全部，更多效果可以下载Demo查看。 ### Item侧滑菜单 <img src="./image/1.gif" width="180px"/> <img src="./image/2.gif" width="180px"/> <img src="./image/3.gif" width="180px"/> ### Item侧滑删除、拖拽 <img src="./image/4.gif" width="180px"/> <img src="./image/5.gif" width="180px"/> <img src="./image/6.gif" width="180px"/> ### 下拉刷新和加载更多 <img src="./image/7.gif" width="180px"/> ### HeaderView和FooterView <img src="./image/8.gif" width="180px"/> ### Sticky效果和Item分组 <img src="./image/9.gif" width="180px"/> <img src="./image/10.gif" width="180px"/> ### 和DrawerLayout嵌套 <img src="./image/11.gif" width="180px"/> ## 如何使用 如果你使用的是android support库，那么请添加下述依赖： ```groovy implementation 'com.yanzhenjie.recyclerview:support:1.3.2' ``` 如果你使用的是android x库，那么请添加下述依赖： ```groovy implementation 'com.yanzhenjie.recyclerview:x:1.3.2' ``` > **1. SwipeRecyclerView从1.3.0版本开始支持AndroidX和二级列表，因此相对于低版本的包名和类名有所改动，从低版本升级的开发者需要考量是否要升级。** **2. 为了让开发者方便切换support库和x库，SwipeRecyclerView的support库和x库除了依赖时的名称不一样外，包名、控件名和类名都是一样的，因此两个库不能共存。** ### 加入布局 在布局的xml中加入`SwipeRecyclerView`： ```xml <com.yanzhenjie.recyclerview.SwipeRecyclerView .../> ``` ### ItemDecoration 也就是分割线，支持Grid形式和Linear形式，可以选择某个ViewType不画分割线： ```java // 默认构造，传入颜色即可。 ItemDecoration itemDecoration = new DefaultDecoration(color); // 或者：颜色，宽，高，最后一个参数是不画分割线的ViewType，可以传入多个。 itemDecoration = new DefaultDecoration(color, width, height, excludeViewType); // 或者：例如下面的123都是不画分割线的ViewType： itemDecoration = new DefaultDecoration(color, width, height, 1, 2, 3); SwipeRecyclerView recyclerView = ...; recyclerView.setDecoration(itemDecoration); ``` ### Item点击监听 ```java recyclerView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(View view, int position) { // TODO... } }); ``` ### 侧滑菜单 ```java // 设置监听器。 swipeRecyclerView.setSwipeMenuCreator(mSwipeMenuCreator); // 创建菜单： SwipeMenuCreator mSwipeMenuCreator = new SwipeMenuCreator() { @Override public void onCreateMenu(SwipeMenu leftMenu, SwipeMenu rightMenu, int position) { SwipeMenuItem deleteItem = new SwipeMenuItem(mContext) ...; // 各种文字和图标属性设置。 leftMenu.addMenuItem(deleteItem); // 在Item左侧添加一个菜单。 SwipeMenuItem deleteItem = new SwipeMenuItem(mContext) ...; // 各种文字和图标属性设置。 leftMenu.addMenuItem(deleteItem); // 在Item右侧添加一个菜单。 // 注意：哪边不想要菜单，那么不要添加即可。 } }; // 菜单点击监听。 swipeRecyclerView.setOnItemMenuClickListener(mItemMenuClickListener); OnItemMenuClickListener mItemMenuClickListener = new OnItemMenuClickListener() { @Override public void onItemClick(SwipeMenuBridge menuBridge, int position) { // 任何操作必须先关闭菜单，否则可能出现Item菜单打开状态错乱。 menuBridge.closeMenu(); // 左侧还是右侧菜单： int direction = menuBridge.getDirection(); // 菜单在Item中的Position： int menuPosition = menuBridge.getPosition(); } }; ``` **注意**：菜单需要设置高度，关于菜单高度： 1. `MATCH_PARENT`，自动适应Item高度，保持和Item一样高，比较推荐; 2. 指定具体的高，比如80; 3. `WRAP_CONTENT`，自身高度，极不推荐; ### 侧滑删除和拖拽 拖拽和侧滑删除的功能默认关闭的，所以先要打开功能： ```java recyclerView.setLongPressDragEnabled(true); // 拖拽排序，默认关闭。 recyclerView.setItemViewSwipeEnabled(true); // 侧滑删除，默认关闭。 ``` 只需要设置上面两个属性就可以进行相应的动作了，如果不需要哪个，不要打开就可以了。 然后监听拖拽和侧滑的动作，进行数据更新： ```java recyclerView.setOnItemMoveListener(mItemMoveListener);// 监听拖拽，更新UI。 OnItemMoveListener mItemMoveListener = new OnItemMoveListener() { @Override public boolean onItemMove(ViewHolder srcHolder, ViewHolder targetHolder) { // 此方法在Item拖拽交换位置时被调用。 // 第一个参数是要交换为之的Item，第二个是目标位置的Item。 // 交换数据，并更新adapter。 int fromPosition = srcHolder.getAdapterPosition(); int toPosition = targetHolder.getAdapterPosition(); Collections.swap(mDataList, fromPosition, toPosition); adapter.notifyItemMoved(fromPosition, toPosition); // 返回true，表示数据交换成功，ItemView可以交换位置。 return true; } @Override public void onItemDismiss(ViewHolder srcHolder) { // 此方法在Item在侧滑删除时被调用。 // 从数据源移除该Item对应的数据，并刷新Adapter。 int position = srcHolder.getAdapterPosition(); mDataList.remove(position); adapter.notifyItemRemoved(position); } }; ``` **特别注意**：如果`LayoutManager`是`List`形式，那么Item拖拽时只能从1-2-3-4这样走，如果你的`LayoutManager`是`Grid`形式的，那么Item可以从1直接到3或者5或者6...，这样数据就会错乱，所以**当`LayoutManager`是Grid形式时**这里要特别注意转换数据位置的算法： ```java @Override public boolean onItemMove(ViewHolder srcHolder, ViewHolder targetHolder) { int fromPosition = srcHolder.getAdapterPosition(); int toPosition = targetHolder.getAdapterPosition(); if (fromPosition < toPosition) { for (int i = fromPosition; i < toPosition; i++) { Collections.swap(mDataList, i, i + 1); } } else { for (int i = fromPosition; i > toPosition; i--) { Collections.swap(mDataList, i, i - 1); } } mMenuAdapter.notifyItemMoved(fromPosition, toPosition); return true; } ``` 我们还可以监听用户的侧滑删除和拖拽Item时的手指状态： ```java recyclerView.setOnItemStateChangedListener(mStateChangedListener); ... private OnItemStateChangedListener mStateChangedListener = (viewHolder, actionState) -> { if (actionState == OnItemStateChangedListener.ACTION_STATE_DRAG) { // 状态：正在拖拽。 } else if (actionState == OnItemStateChangedListener.ACTION_STATE_SWIPE) { // 状态：滑动删除。 } else if (actionState == OnItemStateChangedListener.ACTION_STATE_IDLE) { // 状态：手指松开。 } }; ``` 想用户触摸到某个`Item`时就开始拖拽或者侧滑删除时，只需要调用`startDrag()`和`startSwipe()`并转入当前`Item`的`ViewHoler`即可。 触摸拖拽： ```java swipeRecyclerView.startDrag(ViewHolder); ``` 触摸侧滑删除： ```java swipeRecyclerView.startSwipe(ViewHolder); ``` ### HeaderView和FooterView 主要方法： ```java addHeaderView(View); // 添加HeaderView。 removeHeaderView(View); // 移除HeaderView。 addFooterView(View); // 添加FooterView。 removeFooterView(View); // 移除FooterView。 getHeaderItemCount(); // 获取HeaderView个数。 getFooterItemCount(); // 获取FooterView个数。 getItemViewType(int); // 获取Item的ViewType，包括HeaderView、FooterView、普通ItemView。 ``` 添加/移除`HeaderView`/`FooterView`和`setAdapter()`的调用不分先后顺序。 **特别注意**： 1. 如果添加了`HeaderView`，凡是通过`ViewHolder`拿到的`position`都要减掉`HeaderView`的数量才能得到正确的`position`。 ### 加载更多 本库默认提供了加载更多的动画和View，开发者也可以自定义，默认支持`RecyclerView`自带的三种布局管理器。 默认加载更多： ```java RecyclerView recyclerView = ...； ... recyclerView.useDefaultLoadMore(); // 使用默认的加载更多的View。 recyclerView.setLoadMoreListener(mLoadMoreListener); // 加载更多的监听。 LoadMoreListener mLoadMoreListener = new LoadMoreListener() { @Override public void onLoadMore() { // 该加载更多啦。 ... // 请求数据，并更新数据源操作。 mMainAdapter.notifyDataSetChanged(); // 数据完更多数据，一定要调用这个方法。 // 第一个参数：表示此次数据是否为空。 // 第二个参数：表示是否还有更多数据。 mRecyclerView.loadMoreFinish(false, true); // 如果加载失败调用下面的方法，传入errorCode和errorMessage。 // errorCode随便传，你自定义LoadMoreView时可以根据errorCode判断错误类型。 // errorMessage是会显示到loadMoreView上的，用户可以看到。 // mRecyclerView.loadMoreError(0, "请求网络失败"); } }; ``` 自定义加载更多View也很简单，自定义一个View，并实现一个接口即可： ```java public class DefineLoadMoreView extends LinearLayout implements SwipeRecyclerView.LoadMoreView, View.OnClickListener { private LoadMoreListener mLoadMoreListener; public DefineLoadMoreView(Context context) { super(context); ... setOnClickListener(this); } /** * 马上开始回调加载更多了，这里应该显示进度条。 */ @Override public void onLoading() { // 展示加载更多的动画和提示信息。 ... } /** * 加载更多完成了。 * * @param dataEmpty 是否请求到空数据。 * @param hasMore 是否还有更多数据等待请求。 */ @Override public void onLoadFinish(boolean dataEmpty, boolean hasMore) { // 根据参数，显示没有数据的提示、没有更多数据的提示。 // 如果都不存在，则都不用显示。 } /** * 加载出错啦，下面的错误码和错误信息二选一。 * * @param errorCode 错误码。 * @param errorMessage 错误信息。 */ @Override public void onLoadError(int errorCode, String errorMessage) { } /** * 调用了setAutoLoadMore(false)后，在需要加载更多的时候，此方法被调用，并传入listener。 */ @Override public void onWaitToLoadMore(SwipeRecyclerView.LoadMoreListener loadMoreListener) { this.mLoadMoreListener = loadMoreListener; } /** * 非自动加载更多时mLoadMoreListener才不为空。 */ @Override public void onClick(View v) { if (mLoadMoreListener != null) mLoadMoreListener.onLoadMore(); } } ``` ## 感谢与参考 * [cube-sdk](https://github.com/liaohuqiu/cube-sdk) * [SwipeMenu](https://github.com/TUBB/SwipeMenu/) * [HeaderAndFooterWrapper](https://github.com/hongyangAndroid/baseAdapter/blob/master/baseadapter-recyclerview/src/main/java/com/zhy/adapter/recyclerview/wrapper/HeaderAndFooterWrapper.java) 加载更多的灵感来自`cube-sdk`，侧滑菜单参考了`SwipeMenu`，添加`HeaderView`参考了`HeaderAndFooterWrapper`类，特别感谢上述开源库及其作者。 ## License ```text Copyright 2019 Zhenjie Yan Licensed under the Apache License, Version 2.0 (the "License");

google/guice

Guice (pronounced 'juice') is a lightweight dependency injection framework for Java 11 and above, brought to you by Google.

Guice ==== - **Latest releases:** * **[6.0.0](https://github.com/google/guice/wiki/Guice600) (supports `javax.{inject,servlet,persistence}`, [mostly supports](https://github.com/google/guice/wiki/Guice600#jee-jakarta-transition) `jakarta.inject`)** * **[7.0.0](https://github.com/google/guice/wiki/Guice700) (supports `jakarta.{inject,servlet,persistence}`)** * (6.0.0 & 7.0.0 are equivalent except for their javax/jakarta support.) - **Documentation:** * [User Guide](https://github.com/google/guice/wiki/Motivation), * [6.0.0 javadocs](https://google.github.io/guice/api-docs/6.0.0/javadoc/index.html) * [7.0.0 javadocs](https://google.github.io/guice/api-docs/7.0.0/javadoc/index.html) * [Latest Snapshot javadocs](https://google.github.io/guice/api-docs/latest/javadoc/index.html) - **Continuous Integration:** [](https://github.com/google/guice/actions) - **Mailing Lists:** [User Mailing List](http://groups.google.com/group/google-guice) <br/> - **License:** [Apache 2.0](http://www.apache.org/licenses/LICENSE-2.0) Overview ==== Put simply, Guice alleviates the need for factories and the use of new in your Java code. Think of Guice's @Inject as the new new. You will still need to write factories in some cases, but your code will not depend directly on them. Your code will be easier to change, unit test and reuse in other contexts. Guice embraces Java's type safe nature. You might think of Guice as filling in missing features for core Java. Ideally, the language itself would provide most of the same features, but until such a language comes along, we have Guice. Guice helps you design better APIs, and the Guice API itself sets a good example. Guice is not a kitchen sink. We justify each feature with at least three use cases. When in doubt, we leave it out. We build general functionality which enables you to extend Guice rather than adding every feature to the core framework. Guice aims to make development and debugging easier and faster, not harder and slower. In that vein, Guice steers clear of surprises and magic. You should be able to understand code with or without tools, though tools can make things even easier. When errors do occur, Guice goes the extra mile to generate helpful messages. For an introduction to Guice and a comparison to new and the factory pattern, see [Bob Lee's video presentation](https://www.youtube.com/watch?v=hBVJbzAagfs). After that, check out our [user's guide](https://github.com/google/guice/wiki/Motivation). We've been running Guice in mission critical applications since 2006, and now you can, too. We hope you enjoy it as much as we do. Installation Instructions ==== Guice Core (Maven) ```xml <dependency> <groupId>com.google.inject</groupId> <artifactId>guice</artifactId> <!-- {version} can be 6.0.0, 7.0.0, etc. --> <version>{version}</version> </dependency> ``` Guice Extension (Maven) ```xml <dependency> <groupId>com.google.inject.extensions</groupId> <!-- {extension-name} can be one of: assistedinject, dagger-adapter, grapher, jmx, jndi, persist, spring, testlib or throwingproviders --> <artifactId>guice-{extension-name}</artifactId> <!-- {version} must match the guice core version. --> <version>{version}</version> </dependency> ``` See [Maven Central](https://central.sonatype.com/artifact/com.google.inject/guice/) for more details, including snippets for other build systems such as Gradle, Ivy, sbt, and more. --- [](http://www.drdobbs.com/tools/winners-of-the-18th-jolt-product-excelle/207600666?pgno=6)

A **distributed transaction solution** with high performance and ease of use for **microservices** architecture. ### Distributed Transaction Problem in Microservices Let's imagine a traditional monolithic application. Its business is built up with 3 modules. They use a single local data source. Naturally, data consistency will be guaranteed by the local transaction.  Things have changed in a microservices architecture. The 3 modules mentioned above are designed to be 3 services on top of 3 different data sources ([Pattern: Database per service](http://microservices.io/patterns/data/database-per-service.html)). Data consistency within every single service is naturally guaranteed by the local transaction. **But how about the whole business logic scope?**  ### How Seata do? Seata is just a solution to the problem mentioned above.  Firstly, how to define a **Distributed Transaction**? We say, a **Distributed Transaction** is a **Global Transaction** which is made up with a batch of **Branch Transaction**, and normally **Branch Transaction** is just **Local Transaction**.  There are three roles in Seata Framework: - **Transaction Coordinator(TC):** Maintain status of global and branch transactions, drive the global commit or rollback. - **Transaction Manager(TM):** Define the scope of global transaction: begin a global transaction, commit or rollback a global transaction. - **Resource Manager(RM):** Manage resources that branch transactions working on, talk to TC for registering branch transactions and reporting status of branch transactions, and drive the branch transaction commit or rollback.  A typical lifecycle of Seata managed distributed transaction: 1. TM asks TC to begin a new global transaction. TC generates an XID representing the global transaction. 2. XID is propagated through microservices' invoke chain. 3. RM registers local transaction as a branch of the corresponding global transaction of XID to TC. 4. TM asks TC for committing or rollbacking the corresponding global transaction of XID. 5. TC drives all branch transactions under the corresponding global transaction of XID to finish branch committing or rollbacking.  For more details about principle and design, please go to [Seata wiki page](https://github.com/apache/incubator-seata/wiki). ### History ##### Alibaba - **TXC**: Taobao Transaction Constructor. Alibaba middleware team started this project since 2014 to meet the distributed transaction problems caused by application architecture change from monolithic to microservices. - **GTS**: Global Transaction Service. TXC as an Aliyun middleware product with new name GTS was published since 2016. - **Fescar**: we started the open source project Fescar based on TXC/GTS since 2019 to work closely with the community in the future. ##### Ant Financial - **XTS**: Extended Transaction Service. Ant Financial middleware team developed the distributed transaction middleware since 2007, which is widely used in Ant Financial and solves the problems of data consistency across databases and services. - **DTX**: Distributed Transaction Extended. Since 2013, XTS has been published on the Ant Financial Cloud, with the name of DTX . ##### Seata Community - **Seata** :Simple Extensible Autonomous Transaction Architecture. Ant Financial joins Fescar, which make it to be a more neutral and open community for distributed transaction, and Fescar be renamed to Seata. ## Maven dependency Depending on the scenario, choose one of the two dependencies: `io.seata:seata-all` or `io.seata:seata-spring-boot-starter`. ```xml <properties> <seata.version>2.0.0</seata.version> </properties> <dependencies> <!--dependencies for non-SpringBoot application framework--> <dependency> <groupId>io.seata</groupId> <artifactId>seata-all</artifactId> <version>${seata.version}</version> </dependency> <!--If your project base on `Spring Boot`, you can directly use the following dependencies--> <!--Notice: `seata-spring-boot-starter` has already included `seata-all` dependency--> <dependency> <groupId>io.seata</groupId> <artifactId>seata-spring-boot-starter</artifactId> <version>${seata.version}</version> </dependency> </dependencies> ``` ## Quick Start [Quick Start](https://seata.apache.org/zh-cn/docs/ops/deploy-guide-beginner) ## Documentation You can view the full documentation from Seata Official Website: [Seata Website page](https://seata.apache.org/zh-cn/docs/overview/what-is-seata). ## Reporting bugs Please follow the [template](./.github/ISSUE_TEMPLATE/BUG_REPORT.md) for reporting any issues. ## Security Please do not use our public issue tracker but refer to our [security policy](./SECURITY.md) ## Contributing Contributors are welcomed to join the Seata project.

} ``` > 注意：**方法请求路径慎用`/`开头**。对于`Retrofit`而言，如果`baseUrl=http://localhost:8080/api/test/`，方法请求路径如果是`person`，则该方法完整的请求路径是：`http://localhost:8080/api/test/person`。而方法请求路径如果是`/person`，则该方法完整的请求路径是：`http://localhost:8080/person`。 ### 注入使用 **将接口注入到其它Service中即可使用！** ```java @Service public class BusinessService { @Autowired private UserService userService; public void doBusiness() { // call userService } } ``` **默认情况下，自动使用`SpringBoot`扫描路径进行`RetrofitClient`注册**。你也可以在配置类加上`@RetrofitScan`手工指定扫描路径。 ## HTTP请求相关注解 `HTTP`请求相关注解，全部使用了`Retrofit`原生注解，以下是一个简单说明： | 注解分类|支持的注解 | |------------|-----------| |请求方式|`@GET` `@HEAD` `@POST` `@PUT` `@DELETE` `@OPTIONS` `@HTTP`| |请求头|`@Header` `@HeaderMap` `@Headers`| |Query参数|`@Query` `@QueryMap` `@QueryName`| |path参数|`@Path`| |form-encoded参数|`@Field` `@FieldMap` `@FormUrlEncoded`| | 请求体 |`@Body`| |文件上传|`@Multipart` `@Part` `@PartMap`| |url参数|`@Url`| > 详细信息可参考官方文档：[retrofit官方文档](https://square.github.io/retrofit/) ## 配置属性 组件支持了多个可配置的属性，用来应对不同的业务场景，具体可支持的配置属性及默认值如下： **注意：应用只需要配置要更改的配置项**! ```yaml retrofit: # 全局转换器工厂 global-converter-factories: - com.github.lianjiatech.retrofit.spring.boot.core.BasicTypeConverterFactory - retrofit2.converter.jackson.JacksonConverterFactory # 全局调用适配器工厂(组件扩展的调用适配器工厂已经内置，这里请勿重复配置) global-call-adapter-factories: # 全局日志打印配置 global-log: # 启用日志打印 enable: true # 全局日志打印级别 log-level: info # 全局日志打印策略 log-strategy: basic # 是否聚合打印请求日志 aggregate: true # 全局重试配置 global-retry: # 是否启用全局重试 enable: false # 全局重试间隔时间 interval-ms: 100 # 全局最大重试次数 max-retries: 2 # 全局重试规则 retry-rules: - response_status_not_2xx - occur_io_exception # 全局超时时间配置 global-timeout: # 全局读取超时时间 read-timeout-ms: 10000 # 全局写入超时时间 write-timeout-ms: 10000 # 全局连接超时时间 connect-timeout-ms: 10000 # 全局完整调用超时时间 call-timeout-ms: 0 # 熔断降级配置 degrade: # 熔断降级类型。默认none，表示不启用熔断降级 degrade-type: none # 全局sentinel降级配置 global-sentinel-degrade: # 是否开启 enable: false # 各降级策略对应的阈值。平均响应时间(ms)，异常比例(0-1)，异常数量(1-N) count: 1000 # 熔断时长，单位为 s time-window: 5 # 降级策略（0：平均响应时间；1：异常比例；2：异常数量） grade: 0 # 全局resilience4j降级配置 global-resilience4j-degrade: # 是否开启 enable: false # 根据该名称从#{@link CircuitBreakerConfigRegistry}获取CircuitBreakerConfig，作为全局熔断配置 circuit-breaker-config-name: defaultCircuitBreakerConfig # 自动设置PathMathInterceptor的scope为prototype auto-set-prototype-scope-for-path-math-interceptor: true ``` ## 高级功能 ### 超时时间配置 如果仅仅需要修改`OkHttpClient`的超时时间，可以通过`@RetrofitClient`相关字段修改，或者全局超时配置修改。 ### 自定义OkHttpClient 如果需要修改`OkHttpClient`其它配置，可以通过自定义`OkHttpClient`来实现，步骤如下： **实现`SourceOkHttpClientRegistrar`接口，调用`SourceOkHttpClientRegistry#register()`方法注册`OkHttpClient`** ```java @Component public class CustomOkHttpClientRegistrar implements SourceOkHttpClientRegistrar { @Override public void register(SourceOkHttpClientRegistry registry) { // 注册customOkHttpClient，超时时间设置为1s registry.register("customOkHttpClient", new OkHttpClient.Builder() .connectTimeout(Duration.ofSeconds(1)) .writeTimeout(Duration.ofSeconds(1)) .readTimeout(Duration.ofSeconds(1)) .addInterceptor(chain -> chain.proceed(chain.request())) .build()); } } ``` **通过`@RetrofitClient.sourceOkHttpClient`指定当前接口要使用的`OkHttpClient`** ```java @RetrofitClient(baseUrl = "${test.baseUrl}", sourceOkHttpClient = "customOkHttpClient") public interface CustomOkHttpUserService { /** * 根据id查询用户信息 */ @GET("getUser") User getUser(@Query("id") Long id); } ``` > 注意：组件不会直接使用指定的`OkHttpClient`，而是基于该`OkHttpClient`创建一个新的。 ### 注解式拦截器 组件提供了**注解式拦截器**，支持基于url路径匹配拦截，使用的步骤如下： 1. 继承`BasePathMatchInterceptor` 2. 使用`@Intercept`注解指定要使用的拦截器 > 如果需要使用多个拦截器，在接口上标注多个`@Intercept`注解即可。 #### 继承`BasePathMatchInterceptor`编写拦截处理器 ```java @Component public class PathMatchInterceptor extends BasePathMatchInterceptor { @Override protected Response doIntercept(Chain chain) throws IOException { Response response = chain.proceed(chain.request()); // response的Header加上path.match return response.newBuilder().header("path.match", "true").build(); } } ``` 默认情况下，**组件会自动将`BasePathMatchInterceptor`的`scope`设置为`prototype`**。 可通过`retrofit.auto-set-prototype-scope-for-path-math-interceptor=false`关闭该功能。关闭之后，需要手动将`scope`设置为`prototype`。 ```java @Component @Scope("prototype") public class PathMatchInterceptor extends BasePathMatchInterceptor { } ``` #### 接口上使用`@Intercept`进行标注 ```java @RetrofitClient(baseUrl = "${test.baseUrl}") @Intercept(handler = PathMatchInterceptor.class, include = {"/api/user/**"}, exclude = "/api/user/getUser") // @Intercept() 如果需要使用多个路径匹配拦截器，继续添加@Intercept即可 public interface InterceptorUserService { /** * 根据id查询用户姓名 */ @POST("getName") Response<String> getName(@Query("id") Long id); /** * 根据id查询用户信息 */ @GET("getUser") Response<User> getUser(@Query("id") Long id); } ``` 上面的`@Intercept`配置表示：拦截`InterceptorUserService`接口下`/api/user/**`路径下（排除`/api/user/getUser`）的请求，拦截处理器使用`PathMatchInterceptor`。 ### 自定义拦截注解 有的时候，我们需要在"拦截注解"动态传入一些参数，然后在拦截的时候使用这些参数。 这时候，我们可以使用"自定义拦截注解"，步骤如下： 1. 自定义注解。必须使用`@InterceptMark`标记，并且注解中必须包括`include、exclude、handler`字段。 2. 继承`BasePathMatchInterceptor`编写拦截处理器 3. 接口上使用自定义注解 例如，我们需要"在请求头里面动态加入`accessKeyId`、`accessKeySecret`签名信息才能再发起HTTP请求"，这时候可以自定义`@Sign`注解来实现。 #### 自定义`@Sign`注解 ```java @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.TYPE) @Documented @InterceptMark public @interface Sign { String accessKeyId(); String accessKeySecret(); String[] include() default {"/**"}; String[] exclude() default {}; Class<? extends BasePathMatchInterceptor> handler() default SignInterceptor.class; } ``` 在`@Sign`注解中指定了使用的拦截器是`SignInterceptor`。 #### 实现`SignInterceptor` ```java @Component @Setter public class SignInterceptor extends BasePathMatchInterceptor { private String accessKeyId; private String accessKeySecret; @Override public Response doIntercept(Chain chain) throws IOException { Request request = chain.request(); Request newReq = request.newBuilder() .addHeader("accessKeyId", accessKeyId) .addHeader("accessKeySecret", accessKeySecret) .build(); Response response = chain.proceed(newReq); return response.newBuilder().addHeader("accessKeyId", accessKeyId) .addHeader("accessKeySecret", accessKeySecret).build(); } } ``` > 注意：`accessKeyId`和`accessKeySecret`字段必须提供`setter`方法。 拦截器的`accessKeyId`和`accessKeySecret`字段值会依据`@Sign`注解的`accessKeyId()`和`accessKeySecret()`值自动注入，如果`@Sign`指定的是占位符形式的字符串，则会取配置属性值进行注入。 #### 接口上使用`@Sign` ```java @RetrofitClient(baseUrl = "${test.baseUrl}") @Sign(accessKeyId = "${test.accessKeyId}", accessKeySecret = "${test.accessKeySecret}", include = "/api/user/getAll") public interface InterceptorUserService { /** * 查询所有用户信息 */ @GET("getAll") Response<List<User>> getAll(); } ``` ### 日志打印 组件支持支持全局日志打印和声明式日志打印。 #### 全局日志打印 默认情况下，全局日志打印是开启的，默认配置如下： ```yaml retrofit: # 全局日志打印配置 global-log: # 启用日志打印 enable: true # 全局日志打印级别 log-level: info # 全局日志打印策略 log-strategy: basic # 是否聚合打印请求日志 aggregate: true ``` 四种日志打印策略含义如下： 1. `NONE`：No logs. 2. `BASIC`：Logs request and response lines. 3. `HEADERS`：Logs request and response lines and their respective headers. 4. `BODY`：Logs request and response lines and their respective headers and bodies (if present). #### 声明式日志打印 如果只需要部分请求才打印日志，可以在相关接口或者方法上使用`@Logging`注解。 #### 日志打印自定义扩展 如果需要修改日志打印行为，可以继承`LoggingInterceptor`，并将其配置成`Spring bean`。 ### 请求重试 组件支持支持全局重试和声明式重试。 #### 全局重试 全局重试默认关闭，默认配置项如下： ```yaml retrofit: # 全局重试配置 global-retry: # 是否启用全局重试 enable: false # 全局重试间隔时间 interval-ms: 100 # 全局最大重试次数 max-retries: 2 # 全局重试规则 retry-rules: - response_status_not_2xx - occur_io_exception ``` 重试规则支持三种配置： 1. `RESPONSE_STATUS_NOT_2XX`：响应状态码不是`2xx`时执行重试 2. `OCCUR_IO_EXCEPTION`：发生IO异常时执行重试 3. `OCCUR_EXCEPTION`：发生任意异常时执行重试 #### 声明式重试 如果只有一部分请求需要重试，可以在相应的接口或者方法上使用`@Retry`注解。 #### 请求重试自定义扩展 如果需要修改请求重试行为，可以继承`RetryInterceptor`，并将其配置成`Spring bean`。 ### 熔断降级 熔断降级默认关闭，当前支持`sentinel`和`resilience4j`两种实现。 ```yaml retrofit: # 熔断降级配置 degrade: # 熔断降级类型。默认none，表示不启用熔断降级 degrade-type: sentinel ``` #### Sentinel 配置`degrade-type=sentinel`开启，然后在相关接口或者方法上声明`@SentinelDegrade`注解即可。 记得手动引入`Sentinel`依赖： ```xml <dependency> <groupId>com.alibaba.csp</groupId> <artifactId>sentinel-core</artifactId> <version>1.6.3</version> </dependency> ``` 此外，还支持全局`Sentinel`熔断降级： ```yaml retrofit: # 熔断降级配置 degrade: # 熔断降级类型。默认none，表示不启用熔断降级 degrade-type: sentinel # 全局sentinel降级配置 global-sentinel-degrade: # 是否开启 enable: true # ...其他sentinel全局配置 ``` #### Resilience4j 配置`degrade-type=resilience4j`开启。然后在相关接口或者方法上声明`@Resilience4jDegrade`即可。 记得手动引入`Resilience4j`依赖： ```xml <dependency> <groupId>io.github.resilience4j</groupId> <artifactId>resilience4j-circuitbreaker</artifactId> <version>1.7.1</version> </dependency> ``` 通过以下配置可开启全局resilience4j熔断降级： ```yaml retrofit: # 熔断降级配置 degrade: # 熔断降级类型。默认none，表示不启用熔断降级 degrade-type: resilience4j # 全局resilience4j降级配置 global-resilience4j-degrade: # 是否开启 enable: true # 根据该名称从#{@link CircuitBreakerConfigRegistry}获取CircuitBreakerConfig，作为全局熔断配置 circuit-breaker-config-name: defaultCircuitBreakerConfig ``` 熔断配置管理： 实现`CircuitBreakerConfigRegistrar`接口，注册`CircuitBreakerConfig`。 ```java @Component public class CustomCircuitBreakerConfigRegistrar implements CircuitBreakerConfigRegistrar { @Override public void register(CircuitBreakerConfigRegistry registry) { // 替换默认的CircuitBreakerConfig registry.register(Constants.DEFAULT_CIRCUIT_BREAKER_CONFIG, CircuitBreakerConfig.ofDefaults()); // 注册其它的CircuitBreakerConfig registry.register("testCircuitBreakerConfig", CircuitBreakerConfig.custom() .slidingWindowType(CircuitBreakerConfig.SlidingWindowType.TIME_BASED) .failureRateThreshold(20) .minimumNumberOfCalls(5) .permittedNumberOfCallsInHalfOpenState(5) .build()); } } ``` 通过`circuitBreakerConfigName`指定`CircuitBreakerConfig`。包括`retrofit.degrade.global-resilience4j-degrade.circuit-breaker-config-name`或者`@Resilience4jDegrade.circuitBreakerConfigName` #### 扩展熔断降级 如果用户需要使用其他的熔断降级实现，继承`BaseRetrofitDegrade`，并将其配置`Spring Bean`。 #### 配置fallback或者fallbackFactory (可选) 如果`@RetrofitClient`不设置`fallback`或者`fallbackFactory`，当触发熔断时，会直接抛出`RetrofitBlockException`异常。 用户可以通过设置`fallback`或者`fallbackFactory`来定制熔断时的方法返回值。 > 注意：`fallback`类必须是当前接口的实现类，`fallbackFactory`必须是`FallbackFactory<T>` 实现类，泛型参数类型为当前接口类型。另外，`fallback`和`fallbackFactory`实例必须配置成`Spring Bean`。 `fallbackFactory`相对于`fallback`，主要差别在于能够感知每次熔断的异常原因(cause)，参考示例如下： ```java @Slf4j @Service public class HttpDegradeFallback implements HttpDegradeApi { @Override public Result<Integer> test() { Result<Integer> fallback = new Result<>(); fallback.setCode(100) .setMsg("fallback") .setBody(1000000); return fallback; } } ``` ```java @Slf4j @Service public class HttpDegradeFallbackFactory implements FallbackFactory<HttpDegradeApi> { @Override public HttpDegradeApi create(Throwable cause) { log.error("触发熔断了! ", cause.getMessage(), cause); return new HttpDegradeApi() { @Override public Result<Integer> test() { Result<Integer> fallback = new Result<>(); fallback.setCode(100) .setMsg("fallback") .setBody(1000000); return fallback; } }; } } ``` ### 错误解码器 在`HTTP`发生请求错误(包括发生异常或者响应数据不符合预期)的时候，错误解码器可将`HTTP`相关信息解码到自定义异常中。你可以在`@RetrofitClient`注解的`errorDecoder()` 指定当前接口的错误解码器，自定义错误解码器需要实现`ErrorDecoder`接口： ### 微服务之间的HTTP调用 #### 继承`ServiceInstanceChooser` 用户可以自行实现`ServiceInstanceChooser`接口，完成服务实例的选取逻辑，并将其配置成`Spring Bean`。对于`Spring Cloud` 应用，可以使用如下实现。 ```java @Service public class SpringCloudServiceInstanceChooser implements ServiceInstanceChooser { private LoadBalancerClient loadBalancerClient; @Autowired public SpringCloudServiceInstanceChooser(LoadBalancerClient loadBalancerClient) { this.loadBalancerClient = loadBalancerClient; } /** * Chooses a ServiceInstance URI from the LoadBalancer for the specified service. * * @param serviceId The service ID to look up the LoadBalancer. * @return Return the uri of ServiceInstance */ @Override public URI choose(String serviceId) { ServiceInstance serviceInstance = loadBalancerClient.choose(serviceId); Assert.notNull(serviceInstance, "can not found service instance! serviceId=" + serviceId); return serviceInstance.getUri(); } } ``` #### 指定`serviceId`和`path` ```java @RetrofitClient(serviceId = "user", path = "/api/user") public interface ChooserOkHttpUserService { /** * 根据id查询用户信息 */ @GET("getUser") User getUser(@Query("id") Long id); } ``` ## 全局拦截器 ### 全局应用拦截器 如果我们需要对整个系统的的`HTTP`请求执行统一的拦截处理，可以实现全局拦截器`GlobalInterceptor`, 并配置成`spring Bean`。 ```java @Component public class MyGlobalInterceptor implements GlobalInterceptor { @Override public Response intercept(Chain chain) throws IOException { Response response = chain.proceed(chain.request()); // response的Header加上global return response.newBuilder().header("global", "true").build(); } } ``` ### 全局网络拦截器 实现`NetworkInterceptor`接口，并配置成`spring Bean`。 ## 调用适配器 `Retrofit`可以通过`CallAdapterFactory`将`Call<T>`对象适配成接口方法的返回值类型。组件扩展了一些`CallAdapterFactory`实现： 1. `BodyCallAdapterFactory` - 同步执行`HTTP`请求，将响应体内容适配成方法的返回值类型。 - 任意方法返回值类型都可以使用`BodyCallAdapterFactory`，优先级最低。 2. `ResponseCallAdapterFactory` - 同步执行`HTTP`请求，将响应体内容适配成`Retrofit.Response<T>`返回。 - 只有方法返回值类型为`Retrofit.Response<T>`，才可以使用`ResponseCallAdapterFactory`。 3. 响应式编程相关`CallAdapterFactory` **`Retrofit`会根据方法返回值类型选择对应的`CallAdapterFactory`执行适配处理**，目前支持的返回值类型如下： - `String`：将`Response Body`适配成`String`返回。 - 基础类型(`Long`/`Integer`/`Boolean`/`Float`/`Double`)：将`Response Body`适配成上述基础类型 - 任意`Java`类型： 将`Response Body`适配成对应的`Java`对象返回 - `CompletableFuture<T>`: 将`Response Body`适配成`CompletableFuture<T>`对象返回 - `Void`: 不关注返回类型可以使用`Void` - `Response<T>`: 将`Response`适配成`Response<T>`对象返回 - `Call<T>`: 不执行适配处理，直接返回`Call<T>`对象 - `Mono<T>`: `Project Reactor`响应式返回类型 - `Single<T>`：`Rxjava`响应式返回类型（支持`Rxjava2/Rxjava3`） - `Completable`：`Rxjava`响应式返回类型，`HTTP`请求没有响应体（支持`Rxjava2/Rxjava3`） 可以通过继承`CallAdapter.Factory`扩展`CallAdapter`。 组件支持通过`retrofit.global-call-adapter-factories`配置全局调用适配器工厂： ```yaml retrofit: # 全局转换器工厂(组件扩展的`CallAdaptorFactory`工厂已经内置，这里请勿重复配置) global-call-adapter-factories: # ... ``` 针对每个Java接口，还可以通过`@RetrofitClient.callAdapterFactories`指定当前接口采用的`CallAdapter.Factory`。 > 建议：将`CallAdapter.Factory`配置成`Spring Bean` ### 数据转码器 `Retrofit`使用`Converter`将`@Body`注解的对象转换成`Request Body`，将`Response Body`转换成一个`Java`对象，可以选用以下几种`Converter`： - [Gson](https://github.com/google/gson): com.squareup.Retrofit:converter-gson - [Jackson](https://github.com/FasterXML/jackson): com.squareup.Retrofit:converter-jackson - [Moshi](https://github.com/square/moshi/): com.squareup.Retrofit:converter-moshi - [Protobuf](https://developers.google.com/protocol-buffers/): com.squareup.Retrofit:converter-protobuf - [Wire](https://github.com/square/wire): com.squareup.Retrofit:converter-wire - [Simple XML](http://simple.sourceforge.net/): com.squareup.Retrofit:converter-simplexml - [JAXB](https://docs.oracle.com/javase/tutorial/jaxb/intro/index.html): com.squareup.retrofit2:converter-jaxb - fastJson：com.alibaba.fastjson.support.retrofit.Retrofit2ConverterFactory 组件支持通过`retrofit.global-converter-factories`配置全局`Converter.Factory`，默认的是`retrofit2.converter.jackson.JacksonConverterFactory`。 如果需要修改`Jackson`配置，自行覆盖`JacksonConverterFactory`的`bean`配置即可。 ```yaml retrofit: # 全局转换器工厂 global-converter-factories: - com.github.lianjiatech.retrofit.spring.boot.core.BasicTypeConverterFactory - retrofit2.converter.jackson.JacksonConverterFactory ``` 针对每个`Java`接口，还可以通过`@RetrofitClient.converterFactories`指定当前接口采用的`Converter.Factory`。 > 建议：将`Converter.Factory`配置成`Spring Bean`。 ### 元注解 `@RetrofitClient`、`@Retry`、`@Logging`、`@Resilience4jDegrade`等注解支持元注解、继承以及`@AliasFor`。 ```java @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.TYPE) @Documented @Inherited @RetrofitClient(baseUrl = "${test.baseUrl}") @Logging(logLevel = LogLevel.WARN) @Retry(intervalMs = 200) public @interface MyRetrofitClient { @AliasFor(annotation = RetrofitClient.class, attribute = "converterFactories") Class<? extends Converter.Factory>[] converterFactories() default {GsonConverterFactory.class}; @AliasFor(annotation = Logging.class, attribute = "logStrategy") LogStrategy logStrategy() default LogStrategy.BODY; } ``` ## 其他功能示例 ### form参数 ```java @FormUrlEncoded @POST("token/verify") Object tokenVerify(@Field("source") String source,@Field("signature") String signature,@Field("token") String token); @FormUrlEncoded @POST("message") CompletableFuture<Object> sendMessage(@FieldMap Map<String, Object> param); ``` ### 文件上传 #### 创建MultipartBody.Part ```java // 对文件名使用URLEncoder进行编码 public ResponseEntity importTerminology(MultipartFile file){ String fileName=URLEncoder.encode(Objects.requireNonNull(file.getOriginalFilename()),"utf-8"); okhttp3.RequestBody requestBody=okhttp3.RequestBody.create(MediaType.parse("multipart/form-data"),file.getBytes()); MultipartBody.Part part=MultipartBody.Part.createFormData("file",fileName,requestBody); apiService.upload(part); return ok().build(); } ``` #### `HTTP`上传接口 ```java @POST("upload") @Multipart Void upload(@Part MultipartBody.Part file); ``` ### 文件下载 #### `HTTP`下载接口 ```java @RetrofitClient(baseUrl = "https://img.ljcdn.com/hc-picture/") public interface DownloadApi { @GET("{fileKey}") Response<ResponseBody> download(@Path("fileKey") String fileKey); } ``` #### `HTTP`下载使用 ```java @SpringBootTest(classes = {RetrofitBootApplication.class}) @RunWith(SpringRunner.class) public class DownloadTest { @Autowired DownloadApi downLoadApi; @Test public void download() throws Exception { String fileKey = "6302d742-ebc8-4649-95cf-62ccf57a1add"; Response<ResponseBody> response = downLoadApi.download(fileKey); ResponseBody responseBody = response.body(); // 二进制流 InputStream is = responseBody.byteStream(); // 具体如何处理二进制流，由业务自行控制。这里以写入文件为例 File tempDirectory = new File("temp"); if (!tempDirectory.exists()) { tempDirectory.mkdir(); } File file = new File(tempDirectory, UUID.randomUUID().toString()); if (!file.exists()) { file.createNewFile(); } FileOutputStream fos = new FileOutputStream(file); byte[] b = new byte[1024]; int length; while ((length = is.read(b)) > 0) { fos.write(b, 0, length); } is.close(); fos.close(); } } ``` ### 动态URL 使用`@url`注解可实现动态URL。此时，`baseUrl`配置任意合法url即可。例如： `http://github.com/` 。运行时只会根据`@Url`地址发起请求。 > 注意：`@url`必须放在方法参数的第一个位置，另外，`@GET`、`@POST`等注解上，不需要定义端点路径。 ```java @GET Map<String, Object> test3(@Url String url,@Query("name") String name); ``` ### `DELETE`请求添加请求体 ```java @HTTP(method = "DELETE", path = "/user/delete", hasBody = true) ``` ### `GET`请求添加请求体 `okhttp3`自身不支持`GET`请求添加请求体，源码如下：   作者给出了具体原因，可以参考: [issue](https://github.com/square/okhttp/issues/3154) 但是，如果实在需要这么做，可以使用：`@HTTP(method = "get", path = "/user/get", hasBody = true)`，使用小写`get`绕过上述限制。 ## 反馈建议 如有任何问题，欢迎提issue或者加QQ群反馈。 群号：806714302

🔥应用内悬浮窗，无需一切权限，适配所有ROM和厂商，no permission floating view.

float-button floating floating-view floating-window floatview floatwindow permission-android x-f-c

[](http://www.imuxuan.com/) EnFloatingView ========================== [](https://bintray.com/leotyndale/Muxuan/EnFloatingView) [](http://www.imuxuan.com/) [](http://blog.imuxuan.com) [](https://item.jd.com/12730926.html) [🔥🔥🔥 马上重构你的架构思维](https://item.jd.com/12730926.html) ========================== [English](/README_EN.md) 无需一切权限，不受各种国产ROM限制，默认可以显示的应用内悬浮窗。 ### 传统方案 对于传统悬浮窗和一些古老的“黑科技”悬浮窗的实现，想必已经有很多成熟的案例了，实现策略基本为以下两种： 1. TYPE_SYSTEM_ALERT类型 ```java mWindowManager = (WindowManager)context.getSystemService(Context.WINDOW_SERVICE); WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams() layoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT; ``` ​ 需要权限： ```java <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" ></uses> ``` 2. TYPE_TOAST / TYPE_PHONE 类型 ​ 7.1.1以下不需要权限声明，在魅族、华为、小米等机型上默认隐藏，需要引导用户打开悬浮窗。 ### 传统方案的问题 第一种方案因为存在各种限制，不能被众多开发采纳，故而比较流行的悬浮窗实现方式是第二种。 但是，我们有自己的原则： - 不能接受7.1.1以上机型，使用第二种方式实现悬浮窗仍需要用户主动授予权限的操作？ - 不能接受在魅族、华为、小米等机型上默认隐藏，需要引导用户打开悬浮窗，就像这样  ### 功能 - 应用内显示，无需申请任何权限 - 应用内显示，所有机型都可以默认显示悬浮窗，无需引导用户做更多设置 - 支持拖拽 - 超出屏幕限制移动 - 可自动吸附到屏幕边缘 ### 基本使用规则 1.在gralde的dependencies中加入 ```java compile 'com.imuxuan:floatingview:1.6' ``` 2.在基类Activity（注意必须是基类Activity）中的onStart和onStop（或者安卓原生ActivityLifeCycle监听）中添加如下代码 ```java @Override protected void onStart() { super.onStart(); FloatingView.get().attach(this); } @Override protected void onStop() { super.onStop(); FloatingView.get().detach(this); } ``` 3.展示悬浮窗 ```java FloatingView.get().add(); ``` ### 扩展用法 1.销毁悬浮窗 ```java FloatingView.get().remove(); ``` 2.添加点击事件 ```java FloatingView.get().listener(new MagnetViewListener() { @Override public void onRemove(FloatingMagnetView magnetView) { Toast.makeText(TestActivity.this, "我没了", Toast.LENGTH_SHORT).show(); } @Override public void onClick(FloatingMagnetView magnetView) { Toast.makeText(TestActivity.this, "点到我了", Toast.LENGTH_SHORT).show(); } }); ``` 3.获得悬浮窗View ```java FloatingView.get().getView(); ``` 4.设置悬浮窗icon ```java FloatingView.get().icon(R.drawable.XXXXX); ``` 5.设置悬浮窗View ```java FloatingView.get().customView(new View()); or FloatingView.get().customView(R.layout.XXXXX); ``` 6.设置悬浮窗位置等布局参数 ```java FloatingView.get().layoutParams(new ViewGroup.LayoutParams()); ``` ### 效果图  ### 更新记录 1.6 修复横竖屏切换错位 & 添加到布局时偶发崩溃 1.5 修复内存泄露问题 1.4 适配折叠屏 1.3 增加自定义layout等API 1.2 修复拖拽失效 1.1 点击监听问题处理 1.0 创建项目

📖 介绍 `Frostmourne`(霜之哀伤)是汽车之家经销商技术部监控系统的开源版本，用于帮助监控几乎所有数据库数据(包括`Elasticsearch`, `Prometheus`, `SkyWalking`, `MySql` 等等)。如果你已经建立起了日志系统， 指标体系，却苦恼于没有一个配套监控系统，也许它能帮到你。使用本系统得当，至少可以做到线上应用出了什么问题，相关开发能第一时间了解报错情况，知道问题出在哪里， 可以快速响应处理，几乎先于所有人知道线上的情况，也因为心中有数所以可以从容应对各种问询，一点都不慌，你们团队值得拥有。 ### 项目初衷 在用`ELK`建立起日志系统之后，我们发现应用日志监控这块除了`ElastAlert`之外，没有其他方案。我们初期使用`ElastAlert`来解决日志监控的问题， 但是随着配置的增加，不仅管理成本和使用成本较高，稳定性方面也不能让我们满意，所以为了更好的易用性，稳定性，我们决定自己做一套简单的监控系统， 来解决日志监控的问题。 项目并不局限于`Elasticsearch`数据，还支持`HTTP`, `PING`, `Telnet`监控，`Prometheus`, `SkyWalking`, `InfluxDB`，`MySQL`, `ClickHouse`, `IoTDB`, `SqlServer`数据监控， 后面还会加入更多的常用数据源(如：`Loki`, `MongoDB`, `Redis`, `Oracle` 等)纳入监控范畴，需要做的东西还有很多，需要更多相关开发加入进来，欢迎联系我们，一起做大做强。 # ✨ 主要功能 * 只需要写一条数据查询就可以轻松搞定监控 * 多种数据源支持：`Elasticsearch, HTTP, SkyWalking, Prometheus, InfluxDB, MySQL/TiDb, ClickHouse, SqlServer, PING, IotDB, Telnet` * 数值计算类型监控：`count, min, max, avg, sum, unique count, percentiles, standard deviation`; `Elasticsearch`数据支持分桶 * 多种报警消息发送方式：钉钉(机器人)、企业微信(机器人)、飞书机器人、Email、短信、HTTP * 多种消息格式：`text, markdown` * 灵活的报警消息`Freemarker`模板定制，支持变量占位符；消息模板管理 * 分布式调度实现，每个监控都是独立调度，互不影响 * 报警消息附带日志查询短链接，直达报警原因 * 数值同比，环比监控 * `HTTP`数据监控, `Javascript`表达式判断是否报警; `PING`连通监控, `Telnet`端口连通监控 * 前端简单易用：监控管理、测试、另存、执行日志和历史消息 * `Elasticsearch`数据查询、分享和下载 * 报警消息抑制功能，防止消息轰炸；也有报警升级功能，避免故障相关方长时间得不到通知。 * 自带账号，团队，部门信息管理模块，也可自己实现内部对接 * 集成`LDAP`登录认证 * 权限控制，数据隔离，各团队互不影响 #### 企业微信机器人报警截图展示： （<a href="./doc/wiki/feature_image.md" target="_blank">查看完整功能截图展示</a>） <img src="https://gitee.com/tim_guai/frostmourne/raw/master/doc/wiki/img/markdown_wechat_robot.png" /> <!-- TOC --> ## 目录 - [介绍](#-介绍) - [主要功能](#-主要功能) - [在线demo](#-在线demo) - [快速启动](#-快速启动) - [部署](#-部署) - [环境准备](#预备环境准备mysql数据库表创建) - [k8s部署方式](#一k8s部署方式) - [zip包部署方式](#二zip包部署方式) - [自构建部署方式](#三自构建部署方式) - [功能使用指南](#-功能使用指南) - [开发调试](#-开发调试) - [后续规划](#后续规划) - [发版历史](./ReleaseNotes.md) - [Contributors](#-contributors) <!-- /TOC --> # 💻 在线demo 为了更快的理解本项目的作用，提供了一个接口全`mock`的静态站点供大家预览功能: <a href="https://frostmourne-demo.github.io/">在线demo</a> 在线`demo`更新不及时，请以项目实际运行效果为准，`demo`只是用于快速浏览 # 📦 快速启动 提供`docker-compose`方式，让你更快运行起来便于更好理解项目作用。详细请看文档：<a href="./doc/wiki/quick-start.md" target="_blank">Quick-Start</a> # 🧰 部署 #### 预备环境准备：`MySQL`数据库表创建 > Frostmourne所有表的创建语句都在 [frostmourne.sql](./doc/mysql-schema/frostmourne.sql) 文件中。 数据库密码默认使用明文，没有加密策略。如果你需要对密码进行加密，请参考druid官方文档：[druid数据库密码加密](https://github.com/alibaba/druid/wiki/%E4%BD%BF%E7%94%A8ConfigFilter) #### 一、`k8s`部署方式 `k8s`部署参考以下三个配置文件 * [frostmourne-monitor-namespace.yaml](./doc/docker/k8s/frostmourne-monitor-namespace.yaml) * [frostmourne-monitor-deployment.yaml](./doc/docker/k8s/frostmourne-monitor-deployment.yaml) * [frostmourne-monitor-service.yaml](./doc/docker/k8s/frostmourne-monitor-service.yaml) 相关参数在 `frostmourne-monitor-deployment.yaml` 文件里配置。需要注意的是在`frostmourne-monitor-service.yaml`里指定对外映射端口，默认`nodePort=30054` ```bash kubectl applt -f frostmourne-monitor-namespace.yaml kubectl applt -f frostmourne-monitor-deployment.yaml kubectl apply -f frostmourne-monitor-service.yaml ``` #### 二、`zip`包部署方式 依赖环境 * `JDK 1.8` * `MySQL 5.7.8+` 最新的Release版本zip包，请到 [releases](https://github.com/AutohomeCorp/frostmourne/releases) 中下载，解压后然后根据自己的环境修改应用配置文件`application.properties`文件和环境变量配置文件`env`，然后执行如下命令启动： ```bash ./scripts/startup.sh ``` 执行如下命令停止应用： ```bash ./scripts/shutdown.sh ``` #### 三、自构建部署方式 依赖环境 * `JDK 1.8` * `Maven 3.2.x+` * `MySQL 5.7.8+` 在项目`frostmourne`主目录下执`maven`构建命令： ```bash mvn -U clean package -DskipTests=true ``` 前端项目`frostmourne-vue`会自动把资源构建到`frostmourne-monitor`的`resources/dist`下，所以你只需要部署`frostmourne-monitor`即可。 `frostmourne-monitor`已经配置了`assembly`打包，`target`目录下会生成`zip`包，你只需要将`zip`包解压，然后根据自己的 环境修改应用配置文件`application.properties`文件和环境变量配置文件env，然后执行如下命令启动： ```bash ./scripts/startup.sh ``` 执行如下命令停止应用： ```bash ./scripts/shutdown.sh ``` #

Simple Binary Encoding (SBE) - High Performance Message Codec

c-plus-plus codec encoder-decoder golang java

Simple Binary Encoding (SBE) ============================ [](https://www.javadoc.io/doc/uk.co.real-logic/sbe-tool) [](https://github.com/real-logic/simple-binary-encoding/blob/master/LICENSE) [](https://github.com/real-logic/simple-binary-encoding/actions) [](https://github.com/real-logic/simple-binary-encoding/actions) [SBE](https://github.com/FIXTradingCommunity/fix-simple-binary-encoding) is an OSI layer 6 presentation for encoding and decoding binary application messages for low-latency financial applications. This repository contains the reference implementations in Java, C++, Golang, C#, and Rust. More details on the design and usage of SBE can be found on the [Wiki](https://github.com/real-logic/simple-binary-encoding/wiki). An XSD for SBE specs can be found [here](https://github.com/real-logic/simple-binary-encoding/blob/master/sbe-tool/src/main/resources/fpl/sbe.xsd). Please address questions about the specification to the [SBE FIX community](https://github.com/FIXTradingCommunity/fix-simple-binary-encoding). For the latest version information and changes see the [Change Log](https://github.com/real-logic/simple-binary-encoding/wiki/Change-Log) with **downloads** at [Maven Central](http://search.maven.org/#search%7Cga%7C1%7Csbe). The Java and C++ SBE implementations work very efficiently with the [Aeron](https://github.com/real-logic/aeron) messaging system for low-latency and high-throughput communications. The Java SBE implementation has a dependency on [Agrona](https://github.com/real-logic/agrona) for its buffer implementations. Commercial support is available from [sales@real-logic.co.uk](mailto:sales@real-logic.co.uk?subject=SBE). Binaries -------- Binaries and dependency information for Maven, Ivy, Gradle, and others can be found at [http://search.maven.org](http://search.maven.org/#search%7Cga%7C1%7Csbe). Example for Maven: ```xml <dependency>     <groupId>uk.co.real-logic</groupId>     <artifactId>sbe-all</artifactId>     <version>${sbe.tool.version}</version> </dependency> ``` Build ----- Build the project with [Gradle](http://gradle.org/) using this [build.gradle](https://github.com/real-logic/simple-binary-encoding/blob/master/build.gradle) file. Full clean build: $ ./gradlew Run the Java examples $ ./gradlew runJavaExamples Distribution ------------ Jars for the executable, source, and javadoc for the various modules can be found in the following directories: sbe-benchmarks/build/libs sbe-samples/build/libs sbe-tool/build/libs sbe-all/build/libs An example to execute a Jar from command line using the 'all' jar which includes the Agrona dependency: java -Dsbe.generate.ir=true -Dsbe.target.language=Cpp -Dsbe.target.namespace=sbe -Dsbe.output.dir=include/gen -Dsbe.errorLog=yes -jar sbe-all/build/libs/sbe-all-${SBE_TOOL_VERSION}.jar my-sbe-messages.xml C++ Build using CMake --------------------- NOTE: Linux, Mac OS, and Windows only for the moment. See [FAQ](https://github.com/real-logic/simple-binary-encoding/wiki/Frequently-Asked-Questions). Windows builds have been tested with Visual Studio Express 12. For convenience, the `cppbuild` script does a full clean, build, and test of all targets as a Release build. $ ./cppbuild/cppbuild If you are comfortable using CMake, then a full clean, build, and test looks like: $ mkdir -p cppbuild/Debug $ cd cppbuild/Debug $ cmake ../.. $ cmake --build . --clean-first $ ctest __Note__: The C++ build includes the C generator. Currently, the C generator is a work in progress. Golang Build ------------ First build using Gradle to generate the SBE jar and then use it to generate the golang code for testing. $ ./gradlew $ ./gradlew generateGolangCodecs For convenience on Linux, a gnu Makefile is provided that runs some tests and contains some examples. $ cd gocode # make # test, examples, bench Users of golang generated code should see the [user documentation](https://github.com/real-logic/simple-binary-encoding/wiki/Golang-User-Guide). Developers wishing to enhance the golang generator should see the [developer documentation](https://github.com/real-logic/simple-binary-encoding/blob/master/gocode/README.md) C# Build -------- Users of CSharp generated code should see the [user documentation](https://github.com/real-logic/simple-binary-encoding/wiki/Csharp-User-Guide). Developers wishing to enhance the CSharp generator should see the [developer documentation](https://github.com/real-logic/simple-binary-encoding/blob/master/csharp/README.md) Rust Build ------------ The SBE Rust generator will produce 100% safe rust crates (no `unsafe` code will be generated). Generated crates do not have any dependencies on any libraries (including no SBE libraries). If you don't yet have Rust installed see [Rust: Getting Started](https://www.rust-lang.org/learn/get-started) Generate the Rust codecs $ ./gradlew generateRustCodecs Run the Rust test from Gradle $ ./gradlew runRustTests Or run test directly with `Cargo` $ cd rust $ cargo test License (See LICENSE file for full license) ------------------------------------------- Copyright 2013-2024 Real Logic Limited.

[HugeGraph](https://hugegraph.apache.org/) is a fast-speed and highly-scalable [graph database](https://en.wikipedia.org/wiki/Graph_database). Billions of vertices and edges can be easily stored into and queried from HugeGraph due to its excellent OLTP ability. As compliance to [Apache TinkerPop 3](https://tinkerpop.apache.org/) framework, various complicated graph queries can be achieved through [Gremlin](https://tinkerpop.apache.org/gremlin.html)(a powerful graph traversal language). ## Features - Compliance to [Apache TinkerPop 3](https://tinkerpop.apache.org/), support [Gremlin](https://tinkerpop.apache.org/gremlin.html) & [Cypher](https://en.wikipedia.org/wiki/Cypher) language - Schema Metadata Management, including VertexLabel, EdgeLabel, PropertyKey and IndexLabel - Multi-type Indexes, supporting exact query, range query and complex conditions combination query - Plug-in Backend Store Driver Framework, support `RocksDB`, `Cassandra`, `HBase`, `ScyllaDB`, and `MySQL/Postgre` now and easy to add another backend store driver if needed - Integration with `Flink/Spark/HDFS`, and friendly to connect other big data platforms ## Quick Start ### 1. Docker Way (Convenient for Test) We can use `docker run -itd --name=graph -p 8080:8080 hugegraph/hugegraph` to quickly start an inner HugeGraph server with `RocksDB` (in backgrounds) for **test/dev**. You can visit [doc page](https://hugegraph.apache.org/docs/quickstart/hugegraph-server/#3-deploy) or the [README](hugegraph-server/hugegraph-dist/docker/READEME.md) for more details. ([Docker Compose](./hugegraph-server/hugegraph-dist/docker/example)) > Note: > > 1. The docker image of hugegraph is a convenience release, but not **official distribution** artifacts. You can find more details from [ASF Release Distribution Policy](https://infra.apache.org/release-distribution.html#dockerhub). > > 2. Recommend to use `release tag`(like `1.2.0`) for the stable version. Use `latest` tag to experience the newest functions in development. ### 2. Download Way Visit [Download Page](https://hugegraph.apache.org/docs/download/download/) and refer the [doc](https://hugegraph.apache.org/docs/quickstart/hugegraph-server/#32-download-the-binary-tar-tarball) to download the latest release package and start the server. ### 3. Source Building Way Visit [Source Building Page](https://hugegraph.apache.org/docs/quickstart/hugegraph-server/#33-source-code-compilation) and follow the steps to build the source code and start the server.

# Apache Ignite <a href="https://ignite.apache.org/"><img src="https://github.com/apache/ignite-website/blob/master/assets/images/apache_ignite_logo.svg" hspace="20"/></a> [](https://travis-ci.org/apache/ignite) [](https://www.apache.org/licenses/LICENSE-2.0.html) [](https://search.maven.org/search?q=org.apache.ignite) [](https://ignite.apache.org/download.cgi)  [](https://twitter.com/ApacheIgnite) ## What is Apache Ignite? Apache Ignite is a distributed database for high-performance computing with in-memory speed. <p align="center"> <a href="https://ignite.apache.org"> <img src="https://github.com/apache/ignite-website/blob/master/docs/2.9.0/images/ignite_clustering.png" width="400px"/> </a> </p> * [Technical Documentation](https://ignite.apache.org/docs/latest/) * [JavaDoc](https://ignite.apache.org/releases/latest/javadoc/) * [C#/.NET APIs](https://ignite.apache.org/releases/latest/dotnetdoc/api/) * [C++ APIs](https://ignite.apache.org/releases/latest/cppdoc/) ## Multi-Tier Storage Apache Ignite is designed to work with memory, disk, and Intel Optane as active storage tiers. The memory tier allows using DRAM and Intel® Optane™ operating in the Memory Mode for data storage and processing needs. The disk tier is optional with the support of two options -- you can persist data in an external database or keep it in the Ignite native persistence. SSD, Flash, HDD, or Intel Optane operating in the AppDirect Mode can be used as a storage device. [Read More](https://ignite.apache.org/arch/multi-tier-storage.html) ## Ignite Native Persistence Even though Apache Ignite is broadly used as a caching layer on top of external databases, it comes with its native persistence - a distributed, ACID, and SQL-compliant disk-based store. The native persistence integrates into the Ignite multi-tier storage as a disk tier that can be turned on to let Ignite store more data on disk than it can cache in memory and to enable fast cluster restarts. [Read More](https://ignite.apache.org/arch/persistence.html) ## ACID Compliance Data stored in Ignite is ACID-compliant both in memory and on disk, making Ignite a **strongly consistent** system. Ignite transactions work across the network and can span multiple servers. [Read More](https://ignite.apache.org/features/transactions.html) ## ANSI SQL Support Apache Ignite comes with a ANSI-99 compliant, horizontally scalable, and fault-tolerant SQL engine that allows you to interact with Ignite as with a regular SQL database using JDBC, ODBC drivers, or native SQL APIs available for Java, C#, C++, Python, and other programming languages. Ignite supports all DML commands, including SELECT, UPDATE, INSERT, and DELETE queries as well as a subset of DDL commands relevant for distributed systems. [Read More](https://ignite.apache.org/features/sql.html) ## High-Performance Computing High-performance computing (HPC) is the ability to process data and perform complex calculations at high speeds. Using Apache Ignite as a [high-performance compute cluster](https://ignite.apache.org/use-cases/hpc.html), you can turn a group of commodity machines or a cloud environment into a distributed supercomputer of interconnected Ignite nodes. Ignite enables speed and scale by processing records in memory and reducing network utilization with APIs for data and compute-intensive calculations. Those APIs implement the MapReduce paradigm and allow you to run arbitrary tasks across the cluster of nodes.

changmingxie/tcc-transaction

tcc-transaction是TCC型事务java实现

# TCC-TRANSACTION ## TCC-TRANSACTION是什么 [TCC-TRANSACTION](https://changmingxie.github.io)是一款开源的微服务架构下的TCC型分布式事务解决方案，致力于提供高性能和简单易用的分布式事务服务。 - Try: 尝试执行业务，完成所有业务检查（一致性），预留必须业务资源（准隔离性） - Confirm: 确认执行业务，不作任何业务检查，只使用Try阶段预留的业务资源，满足幂等性 - Cancel: 取消执行业务，释放Try阶段预留的业务资源，满足幂等性 ## 微服务架构中分布式事务问题 随着传统的单体架的构微服务化，原本单体架构中不同模块，被拆分为若干个功能简单、松耦合的服务。 系统微服务化后，内部可能需要调用多个服务并操作多个数据库实现，服务调用的分布式事务问题变的非常突出。 比如支付退款场景需要从各分账方退回平台收益户(退分账)，再退还给付款方。其中**退分账**阶段， 涉及从多个分账方(商家1收益户，商家2收益户，商家3收益户，平台手续费账户)扣款，这些账户分布在不同数据库， 比如商家3收益户扣款失败，其他成功扣款需要回滚，这里需要分布式事务保证一致性。  ## 如何解决 如何解决上面**退分账**中分布式事务问题呢？ 选择使用tcc-transaction框架，执行流程如下： - Try: 商家1收益户->冻结分账金额 商家2收益户->冻结分账金额 商家3收益户->冻结分账金额 平台手续费->冻结手续费 - Try成功 => Confirm: 商家1收益户->扣除分账金额 商家2收益户->扣除分账金额 商家3收益户->扣除分账金额 平台手续费->扣除手续费 平台收益户-> 增加金额(总分账金额+手续费) - Try失败 => Cancel: 商家1收益户->解冻分账金额 商家2收益户->解冻分账金额 商家3收益户->解冻分账金额 平台手续费->解冻手续费 ## 工作原理  第一阶段：主业务服务分别调用所有从业务的 try 操作，并在活动管理器中登记所有从业务服务。当所有从业务服务的 try 操作都调用成功或者某个从业务服务的 try 操作失败，进入第二阶段。 第二阶段：活动管理器根据第一阶段的执行结果来执行 confirm 或 cancel 操作。 如果第一阶段所有 try 操作都成功，则活动管理器调用所有从业务活动的 confirm操作。否则调用所有从业务服务的 cancel 操作。 需要注意的是第二阶段 confirm 或 cancel 操作本身也是满足最终一致性的过程，在调用 confirm 或 cancel 的时候也可能因为某种原因（比如网络）导致调用失败，所以需要活动管理支持重试的能力，同时这也就要求 confirm 和 cancel 操作具有幂等性。 ## 快速开始 [官网](https://changmingxie.github.io) [快速开始](https://changmingxie.github.io/zh-cn/docs/tutorial/quickstart.html) [最新可用版本2.x](https://changmingxie.github.io/zh-cn/blog/tcc-transaction-2.x-release.html) ## 常见问题 [常见问题](https://changmingxie.github.io/zh-cn/docs/faq.html) ## 讨论群 钉钉扫码入群

Exercises and Answers for Java 8 Lambdas book

java-8-lambdas-exercises ======================== This git repository contains support material for the [Java 8 Lambdas](https://www.oreilly.com/library/view/java-8-lambdas/9781449370831/) book. Project Structure ----------------- The overall code layout is: * Code is in `src/main/java` * Tests are in `src/test/java` Within these directories things are organised by package: * Exercises which involve code in `com.insightfullogic.java8.exercises` * Answers are in `com.insightfullogic.java8.answers` Coding questions are all in the form of failing tests, and the package-info.java contains the correct answer to questions which don't involve writing code, such as yes/no questions. For example here are the chapter 2 answers: https://github.com/RichardWarburton/java-8-lambdas-exercises/blob/master/src/main/java/com/insightfullogic/java8/answers/chapter2/package-info.java * Code Examples/Listings are in `com.insightfullogic.java8.examples` The sub-packages then correspond to the chapter number, so the examples for chapter 4 are in `com.insightfullogic.java8.examples.chapter4`. Reporting Issues ---------------- If you find any issues with the exercises or examples then please submit them via the [O'Reilly Errata Page](http://www.oreilly.com/catalog/errata.csp?isbn=0636920030713).

JakeWharton/ProcessPhoenix

Process Phoenix facilitates restarting your application process.

Process Phoenix =============== Process Phoenix facilitates restarting your application process. This should only be used for things like fundamental state changes in your debug builds (e.g., changing from staging to production). Usage ----- Start the default activity in a new process: ```java ProcessPhoenix.triggerRebirth(context); ``` Or, if you want to launch with a specific `Intent`: ```java Intent nextIntent = //... ProcessPhoenix.triggerRebirth(context, nextIntent); ``` To check if your application is inside the Phoenix process to skip initialization in `onCreate`: ```java if (ProcessPhoenix.isPhoenixProcess(this)) { return; } ``` Download -------- ```groovy implementation 'com.jakewharton:process-phoenix:3.0.0' ``` Snapshots of the development version are available in [Sonatype's `snapshots` repository][snap].
