Class UndoRedoHistory

java.lang.Object

cusack.hcg.model.UndoRedoHistory

Deprecated.

@Deprecated
public class UndoRedoHistory
extends java.lang.Object

This class keeps a "net" history of the game--that is, it keeps track of what has been done and undone so that undos and redos can be done. This class is totally type-unsafe, but after spending several hours trying to correctly parameterize this class, PuzzleInstance, etc., I gave up.
