Chapter 356. Twitter Timeline Component Available as of Camel version 2.10 The Twitter Timeline component consumes twitter timeline or update the status of specific user. 356.1. Component Options The Twitter Timeline component supports 9 options, which are listed below. Name Description Default Type accessToken (security) The access token String accessTokenSecret (security) The access token secret String consumerKey (security) The consumer key String consumerSecret (security) The consumer secret String httpProxyHost (proxy) The http proxy host which can be used for the camel-twitter. String httpProxyUser (proxy) The http proxy user which can be used for the camel-twitter. String httpProxyPassword (proxy) The http proxy password which can be used for the camel-twitter. String httpProxyPort (proxy) The http proxy port which can be used for the camel-twitter. int resolveProperty Placeholders (advanced) Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true boolean 356.2. Endpoint Options The Twitter Timeline endpoint is configured using URI syntax: with the following path and query parameters: 356.2.1. Path Parameters (1 parameters): Name Description Default Type timelineType Required The timeline type to produce/consume. TimelineType 356.2.2. Query Parameters (43 parameters): Name Description Default Type user (common) The username when using timelineType=user String bridgeErrorHandler (consumer) Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. false boolean sendEmptyMessageWhenIdle (consumer) If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead. false boolean type (consumer) Endpoint type to use. Only streaming supports event type. polling EndpointType distanceMetric (consumer) Used by the non-stream geography search, to search by radius using the configured metrics. The unit can either be mi for miles, or km for kilometers. You need to configure all the following options: longitude, latitude, radius, and distanceMetric. km String exceptionHandler (consumer) To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. ExceptionHandler exchangePattern (consumer) Sets the exchange pattern when the consumer creates an exchange. ExchangePattern extendedMode (consumer) Used for enabling full text from twitter (eg receive tweets that contains more than 140 characters). true boolean latitude (consumer) Used by the non-stream geography search to search by latitude. You need to configure all the following options: longitude, latitude, radius, and distanceMetric. Double locations (consumer) Bounding boxes, created by pairs of lat/lons. Can be used for streaming/filter. A pair is defined as lat,lon. And multiple paris can be separated by semi colon. String longitude (consumer) Used by the non-stream geography search to search by longitude. You need to configure all the following options: longitude, latitude, radius, and distanceMetric. Double pollStrategy (consumer) A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel. PollingConsumerPoll Strategy radius (consumer) Used by the non-stream geography search to search by radius. You need to configure all the following options: longitude, latitude, radius, and distanceMetric. Double twitterStream (consumer) To use a custom instance of TwitterStream TwitterStream synchronous (advanced) Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). false boolean count (filter) Limiting number of results per page. 5 Integer filterOld (filter) Filter out old tweets, that has previously been polled. This state is stored in memory only, and based on last tweet id. true boolean lang (filter) The lang string ISO_639-1 which will be used for searching String numberOfPages (filter) The number of pages result which you want camel-twitter to consume. 1 Integer sinceId (filter) The last tweet id which will be used for pulling the tweets. It is useful when the camel route is restarted after a long running. 1 long userIds (filter) To filter by user ids for streaming/filter. Multiple values can be separated by comma. String backoffErrorThreshold (scheduler) The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in. int backoffIdleThreshold (scheduler) The number of subsequent idle polls that should happen before the backoffMultipler should kick-in. int backoffMultiplier (scheduler) To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured. int delay (scheduler) Milliseconds before the poll. 30000 long greedy (scheduler) If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the run polled 1 or more messages. false boolean initialDelay (scheduler) Milliseconds before the first poll starts. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour). 1000 long runLoggingLevel (scheduler) The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that. TRACE LoggingLevel scheduledExecutorService (scheduler) Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool. ScheduledExecutor Service scheduler (scheduler) To use a cron scheduler from either camel-spring or camel-quartz2 component none ScheduledPollConsumer Scheduler schedulerProperties (scheduler) To configure additional properties when using a custom scheduler or any of the Quartz2, Spring based scheduler. Map startScheduler (scheduler) Whether the scheduler should be auto started. true boolean timeUnit (scheduler) Time unit for initialDelay and delay options. MILLISECONDS TimeUnit useFixedDelay (scheduler) Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details. true boolean sortById (sort) Sorts by id, so the oldest are first, and newest last. true boolean httpProxyHost (proxy) The http proxy host which can be used for the camel-twitter. Can also be configured on the TwitterComponent level instead. String httpProxyPassword (proxy) The http proxy password which can be used for the camel-twitter. Can also be configured on the TwitterComponent level instead. String httpProxyPort (proxy) The http proxy port which can be used for the camel-twitter. Can also be configured on the TwitterComponent level instead. Integer httpProxyUser (proxy) The http proxy user which can be used for the camel-twitter. Can also be configured on the TwitterComponent level instead. String accessToken (security) The access token. Can also be configured on the TwitterComponent level instead. String accessTokenSecret (security) The access secret. Can also be configured on the TwitterComponent level instead. String consumerKey (security) The consumer key. Can also be configured on the TwitterComponent level instead. String consumerSecret (security) The consumer secret. Can also be configured on the TwitterComponent level instead. String 356.3. Spring Boot Auto-Configuration The component supports 10 options, which are listed below. Name Description Default Type camel.component.twitter-timeline.access-token The access token String camel.component.twitter-timeline.access-token-secret The access token secret String camel.component.twitter-timeline.consumer-key The consumer key String camel.component.twitter-timeline.consumer-secret The consumer secret String camel.component.twitter-timeline.enabled Whether to enable auto configuration of the twitter-timeline component. This is enabled by default. Boolean camel.component.twitter-timeline.http-proxy-host The http proxy host which can be used for the camel-twitter. String camel.component.twitter-timeline.http-proxy-password The http proxy password which can be used for the camel-twitter. String camel.component.twitter-timeline.http-proxy-port The http proxy port which can be used for the camel-twitter. Integer camel.component.twitter-timeline.http-proxy-user The http proxy user which can be used for the camel-twitter. String camel.component.twitter-timeline.resolve-property-placeholders Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true Boolean
