    • getRawChildren

      protected Object[] getRawChildren(Object element)
      Returns the raw list of children for the given element. This array will not be useable by the EMF Compare viewers without prior going through adaptElementsToCompareInput(Object[]).
      Parameters:
      element - The element which children we need.
      Returns:
      The children of this element.

    • adaptElementsToCompareInput

      protected Object[] adaptElementsToCompareInput(Object[] elements)
      Adapt all of the given elements that are not instances of PendingUpdateAdapter into ICompareInput for the emf compare viewers when possible.
      Parameters:
      elements - The elements to adapt.
      Returns:
      The array of adapted elements.

    • notifyChanged

      public void notifyChanged(Notification notification)
      This implementation specializes the EMF implementation to ensure that if more than 30 notifications arrive, the viewer is simply refreshed rather than processing each update separately. This is especially important for when undo is invoked in editor and there are many things to be undone.
