Javadoc

Returns an array of all the listeners that were added to the VetoableChangeSupport object with addVetoableChangeListener().

If some listeners have been added with a named property, then the returned array will be a mixture of VetoableChangeListeners and VetoableChangeListenerProxys. If the calling method is interested in distinguishing the listeners then it must test each element to see if it's a VetoableChangeListenerProxy, perform the cast, and examine the parameter.

 
VetoableChangeListener[] listeners = bean.getVetoableChangeListeners(); 
for (int i = 0; i < listeners.length; i++) { 
if (listeners[i] instanceof VetoableChangeListenerProxy) { 
VetoableChangeListenerProxy proxy = 
(VetoableChangeListenerProxy)listeners[i]; 
if (proxy.getPropertyName().equals("foo")) { 
// proxy is a VetoableChangeListener which was associated 
// with the property named "foo" 
} 
} 
}
