    • Method Detail

      • generateEvent

        public ChangeEvent generateEvent​(ChangeEvent ce)
        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
