  • Eclipse Common API

    Platform runtime

    		 Defines the extension point and plug-in model. It dynamically discovers plug-ins and maintains information about the plug-ins and their extension points in a platform registry. Plug-ins are started up when required according to user operation of the platform. The runtime is implemented using the OSGi framework.

    Resource management (workspace)

    		 Defines API for creating and managing resources (projects, files, and folders) that are produced by tools and kept in the file system.

    Workbench UI

    		 Implements the user cockpit for navigating the platform. It defines extension points for adding UI components such as views or menu actions.  It supplies additional toolkits (JFace and SWT) for building user interfaces. The UI services are structured so that a subset of the UI plug-ins can be used to build rich client applications that are independent of the resource management and workspace model. IDE-centric plug-ins define additional functionality for navigating and manipulating resources.

    Help system

    		 Defines extension points for plug-ins to provide help or other documentation as browsable books.

    Team support

    		 Defines a team programming model for managing and versioning resources. 

    Debug support

    		 Defines a language independent debug model and UI classes for building debuggers and launchers.

    Other utilities

    		 Other utility plug-ins supply functionality such as searching and comparing resources, performing builds using XML configuration files, and dynamically updating the platform from a server.
