Constructor Detail

MergeAnnotation.PropertyForwarder

public MergeAnnotation.PropertyForwarder(java.lang.Object source,
                                         ChangeSupport cs)
Create a new forwarder on behalf of a source using the change support.

Parameters:
source - the new source of events
cs - the ChangeSupport used to manage listeners
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
