You can use an instance of this class as a member field of your bean and delegate various work to it. This class is serializable. When it is serialized it will save (and restore) any listeners that are themselves serializable. Any non-serializable listeners will be skipped during serialization.<P><DL><DT><B>See Also: </B><DD><A HREF="../../serialized-form.html#java.beans.VetoableChangeSupport">Serialized
