    • dispose

      public void dispose()
      Description copied from interface: IContentProvider
      Disposes of this content provider. This is called by the viewer when it is disposed.

      The viewer should not be updated during this call, as it is in the process of being disposed.

      The default implementation does nothing.

      Specified by:
      dispose in interface IContentProvider

    • inputChanged

      public void inputChanged(Viewer v, Object o1, Object o2)
      Description copied from interface: IContentProvider
      Notifies this content provider that the given viewer's input has been switched to a different element.

      A typical use for this method is registering the content provider as a listener to changes on the new input (using model-specific means), and deregistering the viewer from the old input. In response to these change notifications, the content provider should update the viewer (see the add, remove, update and refresh methods on the viewers).

      The viewer should not be updated during this call, as it might be in the process of being disposed.

      The default implementation does nothing.

      Specified by:
      inputChanged in interface IContentProvider
      Parameters:
      v - the viewer
      o1 - the old input element, or null if the viewer did not previously have an input
      o2 - the new input element, or null if the viewer does not have an input
