Method Summary

void	addNode(ModelNode p) Adds a node to this undo.
UndoRecord	makeRedo() Creates a TreeUndo for doing the redo.
void	purgeFinal() If undoes a delete, calls ModelNode.purgeFinal() for this nodes undo records.
void	undo() Does the undo by reparenting the nodes of concern back to the the nodes they were under when the TreeUndo was created.
