| VetoableChangeSupport | | public class VetoableChangeSupport implements java.io.Serializable(Code) | | This is a utility class that can be used by beans that support constrained
properties. You can use an instance of this class as a member field
of your bean and delegate various work to it.

(and restore) any listeners that are themselves serializable. Any
non-serializable listeners will be skipped during serialization.
