PropertyChangeListenerProxy
Stay organized with collections
Save and categorize content based on your preferences.
A class which extends the EventListenerProxy
specifically for adding a PropertyChangeListener
with a "bound" property.
Instances of this class can be added
as PropertyChangeListeners to a bean
which supports firing property change events.
If the object has a getPropertyChangeListeners method
then the array returned could be a mixture of PropertyChangeListener
and PropertyChangeListenerProxy objects.
