Class to manage changes to the element hierarchy.

Warning: serialized objects of this class will not be compatible with future swing releases.

It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.
