Class WeakAdapter

java.lang.Object
com.sun.star.lib.uno.helper.WeakAdapter
All Implemented Interfaces:
XAdapter, XInterface
public class WeakAdapter extends Object implements 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.
