Class WeakListDataListener

java.lang.Object

uk.ac.starlink.util.gui.WeakListDataListener

All Implemented Interfaces:

EventListener, ListDataListener

public class WeakListDataListener
extends Object
implements ListDataListener

List data 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.
