WeakAdapter (Java UNO Runtime Reference)

com.sun.star.lib.uno.helper

## 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.
