EventListenerProxy
abstract class EventListenerProxy<T : EventListener!> : EventListener
Known Direct Subclasses
| PropertyChangeListenerProxy |
A class which extends the EventListenerProxy specifically for adding a PropertyChangeListener with a "bound" property.
|
|
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)
If the bean also implemented the zero argument get listener method:
public PropertyChangeListener[] getPropertyChangeListeners()
then the array may contain inner
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.
