The IPropertyChangeNotifier interface defines a marker interface. Classes that support this interface declare support for event propagation in a specialized manner. Classes that implement this interface must dispatch events for each property of this class and any nested classes publicly exposed as properties. For those properties that are anonymous (complex and not strongly typed), implementing classes provide custom support or directly use the ObjectProxy class. Implementors of this interface should use the PropertyChangeEvent.createUpdateEvent() method to construct an appropriate update event for dispatch.
