|---|---|
|  Collection | getAdded()Return the collection of values that need to be added to the managed container. | 
|  Collection | getChanged()Return the set of elements that have changed. | 
|  int | getNextSequence()The next element sequence value for this proxy at load time. | 
|  Collection | getRemoved()Return the set of values that need to be removed from the managed container. | 
|  boolean | isTracking()Return true if this tracker has an up-to-date view of all the changes to the container it is managing. | 
|  void | setNextSequence(int seq)The maximum element sequence value for this proxy at load time. | 
|  void | startTracking()Reset the state of the change tracker, and turn change tracking back on if it has been disabled. | 
|  void | stopTracking()Tell the tracker to stop tracking changes for its container. |
