- All Implemented Interfaces:
- ItemListener, EventListener
public class WeakItemListener
- extends Object
- implements ItemListener
Item listener which delegates to another one as long as it is
reachable, but only retains a weak reference to it.
Adding a listener to an object in this way will not prevent the listener
(and any of its references) from being garbage collected.
