    - #### init

          public void init​(ICommonOutlinePage outlinePage)

      Description copied from class: `OutlineContribution`
      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.

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

    - #### dispose

          public void dispose()

      Description copied from class: `OutlineContribution`
      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.

      Specified by:
        `dispose` in interface `IOutlineContribution`
      Overrides:
        `dispose` in class `OutlineContribution`

    - #### disposeAction

          protected void disposeAction​(org.eclipse.jface.action.IAction action)
