    • getElements

      public Object[] getElements(Object input)
      Description copied from interface: IStructuredContentProvider
      Returns the elements to display in the viewer when its input is set to the given element. These elements can be presented as rows in a table, items in a list, etc. The result is not modified by the viewer.
      Specified by:
      getElements in interface IStructuredContentProvider
      Parameters:
      input - the input element
      Returns:
      the array of elements to display in the viewer
    • inputChanged

      public void inputChanged(Viewer viewer, Object oldInput, Object newInput)
      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:
      viewer - the viewer
      oldInput - the old input element, or null if the viewer did not previously have an input
      newInput - the new input element, or null if the viewer does not have an input
    • 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
