动作 - 通用撤销/重做API？ [英] ActionScript - General Undo / Redo API?

问题描述

我一直不成功尝试创建自己的撤销/重做，与任何类型的可能撤消的正常工作类和重做命令。

i've been unsuccessfully attempting to create my own undo/redo classes that work well with any type of possible undo and redo commands.

例如，我简单的类能很好的撤销/重做x和显示对象或撤消y位置/重做滑块等的值，但事情变得冒险，当我尝试定制我的课也有像工作添加和删​​除项目的清单。

for example, my simple class works perfectly with undoing/redoing x and y positions of display objects or undoing/redoing values of sliders, etc., but things get dicey when i try to tailor my classes to also work with things like adding and removing items to a list.

有任何众所周知的的有据可查的解决方案一般撤销和重做的动作（没有的Flex）？

is there any well known and well documented solution for general undoing and redoing for actionscript (without Flex)?
