16  * This interface should be implemented by selection listeners
17  * that want to be notified when the selection becomes <code>null</code>.
18  * It has no methods. It simply indicates the desire to receive
19  * <code>null</code> selection events through the existing
20  * <code>selectionChanged</code> method. Either the part or the
21  * selection may be <code>null</code>.
