class
EventListenerProxy
extends Object
implements
EventListener
java.lang.Object | |
↳ | java.util.EventListenerProxy<T extends java.util.EventListener> |
An abstract wrapper class for an EventListener
class
which associates a set of additional parameters with the listener.
Subclasses must provide the storage and accessor methods
for the additional arguments or parameters.
For example, a bean which supports named properties
would have a two argument method signature for adding
a PropertyChangeListener
for a property:
public void addPropertyChangeListener(String propertyName, PropertyChangeListener listener)
public PropertyChangeListener[] getPropertyChangeListeners()
PropertyChangeListeners
which are also PropertyChangeListenerProxy
objects.
If the calling method is interested in retrieving the named property then it would have to test the element to see if it is a proxy class.
