Class WeakAdapter

java.lang.Object

com.sun.star.lib.uno.helper.WeakAdapter

All Implemented Interfaces:

com.sun.star.uno.XAdapter, com.sun.star.uno.XInterface

public class WeakAdapter
extends Object
implements com.sun.star.uno.XAdapter

An XAdapter implementation that holds a weak reference (java.lang.ref.WeakReference) to an object. Clients can register listener (com.sun.star.lang.XReference) which are notified when the object (the one which is kept weak) is being finalized. That is, that object is being destroyed because there are not any hard references to it.
