  • Field Details

  • Constructor Details

    • RegisteredExtensionPoint

      RegisteredExtensionPoint​(ExtensionPoint<A> ep, ClassLoader classLoader)
      Create a new registered extension point by copying the information from the parameter.

  • Method Details

    • getId

      public String getId()
      Description copied from interface: ExtensionPoint
      Get the ID of the extension point.
      Specified by:
      getId in interface ExtensionPoint<A extends Action>
      Returns:
      A non-null unique identifier value

    • getName

      public String getName()
      Description copied from interface: ExtensionPoint
      Get the name of the extension point. This is just for display purposes and the value is optional. If no name is given the ID can be used instead.
      Specified by:
      getName in interface ExtensionPoint<A extends Action>

    • getDescription

      public String getDescription()
      Description copied from interface: ExtensionPoint
      Get a description of the extension point. This value is optional but we recommend that the description contains a text documenting the extension point and has information that is useful for everyone who wants to implement extensions for the extension point. This should include context specific information.
      Specified by:
      getDescription in interface ExtensionPoint<A extends Action>
      Returns:
      An optional description

    • getActionClass

      public Class<A> getActionClass()
      Description copied from interface: ExtensionPoint
      Get the class object that represents the type of action that can be added to this extension point. The class must implement the Action interface. Extensions that are extending this extension point must provide an ActionFactory that is capable of creating instances of the specified class.
      Specified by:
      getActionClass in interface ExtensionPoint<A extends Action>
      Returns:
      The class of the actions that can be used on this extension point (required)

    • getRendererFactory

      public RendererFactory<? super A> getRendererFactory()
      Description copied from interface: ExtensionPoint
      This is an optional factory for creating Renderer instances. Renderers are not a required part of the extension system, but will make it easier to write the code for extension points.
      Specified by:
      getRendererFactory in interface ExtensionPoint<A extends Action>
      Returns:
      A renderer factory or null

    • allowRendererOverride

      public boolean allowRendererOverride()
      Description copied from interface: ExtensionPoint
      If an extension is allowed to override the renderer factory with an implementation of its own. This can be seen as a possibility where extensions can create their own look and feel. If strict compliance is needed overriding should of course not be allowed.
      Specified by:
      allowRendererOverride in interface ExtensionPoint<A extends Action>
      Returns:
      TRUE to allow extensions to override, FALSE otherwise

    • getErrorHandlerFactory

      public ErrorHandlerFactory<? super A> getErrorHandlerFactory()
      Description copied from interface: ExtensionPoint
      Get the error handler factory that should be used with this extension point.
      Specified by:
      getErrorHandlerFactory in interface ExtensionPoint<A extends Action>
      Returns:
      An error handler factory, or null to use the system default

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • update

      void update​(ExtensionPoint<A> ep, ClassLoader classLoader)
      Update the registered information.

    • addExtension

      void addExtension​(Registry.RegisteredExtension<A> extension)
      Add an extension to this extension point.

    • removeExtension

      void removeExtension​(String id)
      Remove the extension with a given ID.

    • getExtensions

      Collection<Registry.RegisteredExtension<A>> getExtensions()
      Get all extensions registered with this extension point.

      void clearError()

    • getLastError

      Throwable getLastError()
