Class WeakAdapter

  • All Implemented Interfaces:
    com.sun.star.uno.XAdapter, com.sun.star.uno.XInterface
    public class WeakAdapter
extends java.lang.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.
