   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   This invention relates to file system presentations, and particularly to systems, methods, and computer program products for graphical user interface presentation to implement filtering of a large unbounded hierarchy to avoid repetitive navigation. 
   2. Description of Background 
   In file system presentations there are mechanisms that allow the user to create shortcuts using the functionality of the system e.g. links, or create shortcuts in the presentation layer to go directly to one of the branches of the hierarchy. In database systems filtering is typically accomplished by writing some SQL, or interacting with some dialog interface to filter the data returned, which in turn modifies a query. For example, a user must interact with a dialog. navigate and reproduce the view they already have in their tree display to create a filter, which is exactly the problem that creating a filter should address. 
   When navigating large databases of hierarchical information, users must often traverse though multiple levels of the hierarchy to navigate to the location in the hierarchy in which they have an interest. Systems that do not persist the expansion of the hierarchy from one session to the next require that the user perform this navigation in any new session where they want to navigate to the same location. Systems that do persist the expansion do so at the expense of recreating the expansion automatically and filling the user interface with the hierarchy above the location of interest. In either approach, the representation of the hierarchy is complete from the root of the hierarchy down to the location of interest, often forcing the user to see a large amount of extraneous information. 
   There are many kinds of filtering mechanisms available in products available in the marketplace. For example, type based filters allow the user to pick from a list of object types they either want to include or exclude in the hierarchical display. Some filtering mechanisms allow the user to specify a logical expression that includes one or more properties of an object, and include or exclude objects where the expressions match. The Eclipse framework includes a mechanism called “Working Sets” that allows the user to arbitrarily choose nodes in the hierarchy to include in a named working set, and then specify which working set is visible in the hierarchy at any given time. In the Eclipse approach, the user must find the objects of interest in a popup dialog rather than immediately in the view they are operating in, and the resulting filtered view includes all objects between the selected objects and the root. 
   SUMMARY OF THE INVENTION 
   Exemplary embodiments include a method of graphical user interface presentation to implement filtering of the file hierarchy tree, the method including retrieving the file hierarchy tree for presentation on the display, the file hierarchy tree representative of a plurality of nodes, navigating the file hierarchy tree to identify nodes for selection in a sub-group of nodes, for each of the sub-group of nodes of the plurality of nodes, receiving a node selection signal indicative of the selection device pointing on a selected node from the file hierarchy tree, in response to the node selection signal, presenting the selected node with a highlight on the display, receiving a menu selection signal indicative of the selection device pointing at one of the sub-group of nodes, in response to the menu selection signal, displaying a menu on the display including an option to create a filter, receiving a filter creation selection signal indicative of the selection device pointing at the option to create the filter, in response to receiving the filter creation signal, displaying a popup dialog box on the display, the popup dialog box including an option to create a new filter and edit an existing filter, receiving a dialog box selection signal indicative of the selection device pointing at a selection button on the dialog box and displaying a filtered hierarchy tree on the display, the filtered hierarchy tree including the sub-group of nodes. The method can further include in response to the dialog box selection signal, receiving a new filter name when a create a new filter selection signal is received with the dialog box selection signal.

   DETAILED DESCRIPTION OF THE INVENTION 
   In exemplary embodiments, the systems and methods described herein, the user can specify a filter by using the representation of the hierarchy that the user has been navigating, and can present the filtered objects as new root objects such that the user is not exposed to extraneous hierarchical objects between the objects of interest and the root object. In exemplary embodiments, specifying a filter is faster and requires many fewer mouse clicks, and the resulting filtered view is void of extraneous nodes, thereby simplifying interaction. 
     FIG. 1  illustrates an exemplary embodiment of a system  100  for graphical user interface presentation to implement filtering of a large unbounded hierarchy to avoid repetitive navigation. The methods described herein can be implemented in software (e.g., firmware), hardware, or a combination thereof. In exemplary embodiments, the methods described herein are implemented in software, as an executable program, and is executed by a special or general-purpose digital computer, such as a personal computer, workstation, minicomputer, or mainframe computer. The system  100  therefore includes general-purpose computer  101 . 
   In exemplary embodiments, in terms of hardware architecture, as shown in  FIG. 1 , the computer  101  includes a processor  101 , memory  110  coupled to a memory controller  115 , and one or more input and/or output (I/O) devices  140 ,  145  (or peripherals) that are communicatively coupled via a local input/output controller  135 . The input/output controller  135  can be, for example but not limited to, one or more buses or other wired or wireless connections, as is known in the art. The input/output controller  135  may have additional elements, which are omitted for simplicity, such as controllers, buffers (caches), drivers, repeaters, and receivers, to enable communications. Further, the local interface may include address, control, and/or data connections to enable appropriate communications among the aforementioned components. 
   The processor  105  is a hardware device for executing software, particularly that stored in memory  110 . The processor  105  can be any custom made or commercially available processor, a central processing unit (CPU), an auxiliary processor among several processors associated with the computer  101 , a semiconductor based microprocessor (in the form of a microchip or chip set), a macroprocessor, or generally any device for executing software instructions. 
   The memory  110  can include any one or combination of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, SDRAM, etc.)) and nonvolatile memory elements (e.g., ROM, erasable programmable read only memory (EPROM), electronically erasable programmable read only memory (EEPROM), programmable read only memory (PROM), tape, compact disc read only memory (CD-ROM), disk, diskette, cartridge, cassette or the like, etc.). Moreover, the memory  110  may incorporate electronic, magnetic, optical, and/or other types of storage media. Note that the memory  110  can have a distributed architecture, where various components are situated remote from one another, but can be accessed by the processor  105 . 
   The software in memory  110  may include one or more separate programs, each of which comprises an ordered listing of executable instructions for implementing logical functions. In the example of  FIG. 1 , the software in the memory  110  includes the graphical user interface presentation methods described herein in accordance with exemplary embodiments and a suitable operating system (OS)  111 . The operating system  111  essentially controls the execution of other computer programs, such the graphical user interface presentation systems and methods described herein, and provides scheduling, input-output control, file and data management, memory management, and communication control and related services. 
   The graphical user interface presentation methods described herein may be in the form of a source program, executable program (object code), script, or any other entity comprising a set of instructions to be performed. When a source program, then the program needs to be translated via a compiler, assembler, interpreter, or the like, which may or may not be included within the memory  110 , so as to operate properly in connection with the OS  111 . Furthermore, the graphical user interface presentation methods can be written as an object oriented programming language, which has classes of data and methods, or a procedure programming language, which has routines, subroutines, and/or functions. 
   In exemplary embodiments, a conventional keyboard  150  and mouse  155  can be coupled to the input/output controller  135 . Other output devices such as the I/O devices  140 ,  145  may include input devices, for example but not limited to a printer, a scanner, microphone, and the like. Finally, the I/O devices  140 ,  145  may further include devices that communicate both inputs and outputs, for instance but not limited to, a NIC or modulator/demodulator (for accessing other files, devices, systems, or a network), a radio frequency (RF) or other transceiver, a telephonic interface, a bridge, a router, and the like. The system  100  can further include a display controller  125  coupled to a display  130 . In exemplary embodiments, the system  100  can further include a network interface  160  for coupling to a network  165 . The network  165  can be an IP-based network for communication between the computer  110  and any external server, client and the like via a broadband connection. The network  165  transmits and receives data between the computer  101  and external systems. In exemplary embodiments, network  165  can be a managed IP network administered by a service provider. The network  165  may be implemented in a wireless fashion, e.g., using wireless protocols and technologies, such as WiFi, WiMax, etc. The network  165  can also be a packet-switched network such as a local area network, wide area network, metropolitan area network, Internet network, or other similar type of network environment. The network  165  may be a fixed wireless network, a wireless local area network (LAN), a wireless wide area network (WAN) a personal area network (PAN), a virtual private network (VPN), intranet or other suitable network system and includes equipment for receiving and transmitting signals. 
   If the computer  101  is a PC, workstation, intelligent device or the like, the software in the memory  110  may further include a basic input output system (BIOS) (omitted for simplicity). The BIOS is a set of essential software routines that initialize and test hardware at startup, start the OS  111 , and support the transfer of data among the hardware devices. The BIOS is stored in ROM so that the BIOS can be executed when the computer  101  is activated. 
   When the computer  101  is in operation, the processor  105  is configured to execute software stored within the memory  110 , to communicate data to and from the memory  110 , and to generally control operations of the computer  101  pursuant to the software. The graphical user interface presentation methods described herein and the OS  111 , in whole or in part, but typically the latter, are read by the processor  105 , perhaps buffered within the processor  105 , and then executed. 
   When the systems and methods described herein are implemented in software, as is shown in  FIG. 1 , it the methods can be stored on any computer readable medium, such as storage  120 , for use by or in connection with any computer related system or method. In the context of this document, a computer readable medium is an electronic, magnetic, optical, or other physical device or means that can contain or store a computer program for use by or in connection with a computer related system or method. The graphical user interface presentation methods described herein can be embodied in any computer-readable medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions. In exemplary embodiments, a “computer-readable medium” can be any means that can store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. The computer readable medium can be, for example but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, device, or propagation medium. More specific examples (a non-exhaustive list) of the computer-readable medium would include the following: an electrical connection (electronic) having one or more wires, a portable computer diskette (magnetic), a random access memory (RAM) (electronic), a read-only memory (ROM) (electronic), an erasable programmable read-only memory (EPROM, EEPROM, or Flash memory) (electronic), an optical fiber (optical), and a portable compact disc read-only memory (CDROM) (optical). Note that the computer-readable medium could even be paper or another suitable medium upon which the program is printed, as the program can be electronically captured, via for instance optical scanning of the paper or other medium, then compiled, interpreted or otherwise processed in a suitable manner if necessary, and then stored in a computer memory. 
   In exemplary embodiments, where the graphical user interface presentation methods are implemented in hardware, the graphical user interface presentation methods described herein can implemented with any or a combination of the following technologies, which are each well known in the art: a discrete logic circuit(s) having logic gates for implementing logic functions upon data signals, an application specific integrated circuit (ASIC) having appropriate combinational logic gates, a programmable gate array(s) (PGA), a field programmable gate array (FPGA), etc. 
   In exemplary embodiments, one or more processes in the memory  110  can monitor activity from the keyboard  150  and the mouse  155  or a combination thereof. The processes can further monitor long-running jobs that have been initiated on the computer  101 . The processes can further monitor which and how many other machines can control the computer  101  either locally or remotely. In exemplary embodiments, the processes can also inquire or accept a grace period input by a user of the computer  101 . The grace period can be a time period after which all traffic to and from the computer ceases if no further activity has been sensed by the processes. In this way, if a user has left the computer  101  for an extended period of time or has left the computer (e.g., after a work day) the computer  101  no longer allows traffic to and from the computer  101 . In an alternative implementation, the computer  101  can totally power down after the grace period has expired. In further exemplary embodiments, the processes can accept traffic only from a common network maintenance control system that provides limited services. 
   In exemplary embodiments, the user can interact directly with the presentation they are using to create the filter. In exemplary embodiments, the user has already navigated through the hierarchy and does not want to repeat the navigation. The systems and methods described herein enable the user to select as many nodes in the hierarchy as they want, and then gesture to create a filtered view that shows only those nodes they selected at the root of the tree. In creating the filter, the user names the filter so that they may reuse it in the future. The user may switch between filters, and between filtered and unfiltered views of the data. 
     FIG. 2  illustrates a file hierarchy tree  200  in which the user has selected any nodes in the tree  200  that the user would like to see in a filtered view in accordance with exemplary embodiments. In this example five nodes are selected.  FIG. 3  illustrates the file hierarchy tree  200  of  FIG. 2  in which the user has selected a “Filter . . . ” command from a menu  300  in accordance with exemplary embodiments.  FIG. 4  illustrates an exemplary popup dialog  400 . In the popup dialog  400 , the user can type in a name for the filter and hit “OK”.  FIG. 5  illustrates a filtered hierarchy tree  500  in accordance with exemplary embodiments. The tree  500  now shows only the nodes selected for the filter as root nodes. If necessary, context may be shown for the selection in an address bar or a hover bubble. 
   In exemplary embodiments, the user may select directly in their tree view to create the filter by pointing and clicking. Furthermore, the filter is named, persistent and reusable. In addition, the filter may be constructed using any nodes visible to the user in the tree. 
     FIG. 6  illustrates a flowchart of a method  600  for graphical user interface presentation to implement filtering of a large unbounded hierarchy to avoid repetitive navigation in accordance with exemplary embodiments. At block  610 , the method  600  retrieves the file hierarchy tree having a series of nodes for presentation on the display  130 . At block  620 , the user can navigate the file hierarchy tree to identify nodes for selection in a sub-group of nodes. At block  630 , the user selects the nodes for a filtered view. In exemplary embodiments, for each of the sub-group of nodes, the method  600  highlights each of the selected nodes on the display  130  as shown in  FIG. 2 . The user can then select a Filter command as shown in  FIG. 3  at block  640 . At block  650 , the user can select a filter name, either by creating a new filter or editing an existing filter, in which case, the user can add or remove nodes for the filtered view. At block  660 , the method  600  then displays the filtered hierarchy tree as shown in  FIG. 5 .
