    • init

      public void init(ICommonOutlinePage outlinePage)
      Initializes this contribution. This method is called after the outline page's tree viewer has been created.

      This method may be extended by subclasses. Subclasses must call the superclass implementation.

      OutlineDragAndDropContribution extends this method to add drag and drop support to the outline. The feedback enablement for the drop support is governed by the lexical sort preference.

      Specified by:
      init in interface IOutlineContribution
      Overrides:
      init in class OutlineContribution
      Parameters:
      outlinePage - the contribution's outline page (never null)

    • dispose

      public void dispose()

      Disposes of this contribution. Implementors should clean up any resources associated with this contribution. Note that there is no guarantee that init() has been called. This method has no effect if this contribution has already been disposed.

      This method may be extended by subclasses. Subclasses must call the superclass implementation.
