      public ChangeType getType()
    • generateEvent

      Description copied from class: ChangeForwarder

      Return the new event to represent the originating event ce.

      The returned ChangeEvent is the event that will be fired, and should be built from information in the original event. If it is null, then no event will be fired.

      The default implementation just constructs a ChangeEvent of the same type that chains back to ce.

      Overrides:
      generateEvent in class ChangeForwarder
      Parameters:
      ce - the originating ChangeEvent
      Returns:
      a new ChangeEvent to pass on, or null if no event should be sent
      Throws:
      ChangeVetoException - if for any reason this event can't be handled
