java.lang.Objectjava.util.EventListenerProxy
java.beans.VetoableChangeListenerProxy
A class which extends the EventListenerProxy specifically
for associating a VetoableChangeListener with a "constrained"
property. Instances of this class can be added as a
VetoableChangeListener to a bean which supports firing
VetoableChange events.
If the object has a getVetoableChangeListeners()
method then the array returned could be a mixture of
VetoableChangeListener and
VetoableChangeListenerProxy objects.
