Class WeakAdapter

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 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.
