<p> <span>StateEdit是更改状态的对象的一般编辑。</span> <span>被编辑的对象必须符合StateEditable界面。</span> </p>
<p> <span>这个编辑类通过在编辑之前和之后询问对象来存储它在Hashtables中的状态。</span> <span>撤消或重做时，对象被告知要从这些Hashtables恢复它的状态。</span> </p>
<span>使用状态编辑如下：</span>
<pre>  <span>// Create the edit during the "before" state of the object
      StateEdit newEdit = new StateEdit(myObject);
