Hashtable | RecordState () |
void | ApplyState (Hashtable values) |
void | OnExitScope () |
An interface that enables objects to store and load undo-able states.
void GILES.IUndo.ApplyState | ( | Hashtable | values | ) |
Apply the recorded state to the target object using the values stored by RecordState.
Implemented in GILES.UndoDelete, GILES.UndoInstantiate, GILES.UndoReflection, GILES.UndoSelection, GILES.UndoOffsetHolder, and GILES.UndoTransform.
void GILES.IUndo.OnExitScope | ( | ) |
Called when a state is purged from the undo or redo stack. Commonly used by objects to release memory once no longer needed.
Implemented in GILES.UndoDelete, GILES.UndoInstantiate, GILES.UndoOffsetHolder, GILES.UndoReflection, GILES.UndoSelection, and GILES.UndoTransform.
Hashtable GILES.IUndo.RecordState | ( | ) |
Record the current state of the target object. RecordState() should grab the current state of the object pointed to, not the current state as stored.
RecordState should return a hashtable that contains all the information necessary to reconstitute the object. How the data is stored is up to the implementation, since it is also left to the implementing class to reconstruct itself using this same information in ApplyState.
Implemented in GILES.UndoDelete, GILES.UndoInstantiate, GILES.UndoOffsetHolder, GILES.UndoReflection, GILES.UndoSelection, and GILES.UndoTransform.
