This class is used for registering and disposing the native data associated with java objects. The object can register itself by calling one of the addRecord methods and providing either the pointer to the native disposal method or a descendant of the DisposerRecord class with overridden dispose() method. When the object becomes unreachable, the dispose() method of the associated DisposerRecord object will be called.
