<span><code>TreePath</code>表示唯一标识树中某个节点的路径的对象数组。</span>
<span>数组的元素以root为单位，作为数组的第一个元素。</span>
<span>例如，文件系统上的一个文件是基于父目录的数组和文件的名称来唯一标识的。</span>
<span>路径<code>/tmp/foo/bar</code>可以由<code>TreePath</code>为<code>new TreePath(new Object[] {"tmp", "foo", "bar"})</code> 。</span>
<p> <span><code>TreePath</code>被广泛使用<code>JTree</code>和相关类。</span> <span>例如， <code>JTree</code>表示选择作为阵列<code>TreePath</code>秒。</span> <span>当与<code>JTree</code>一起使用时，路径的元素是从<code>TreeModel</code>返回的对象。</span> <span>当<code>JTree</code>与<code>DefaultTreeModel</code>配对时，路径的元素为<code>TreeNode</code> s。</span> <span>以下示例说明从选择JTree中<code>JTree</code>用户对象：</span> </p>
<pre>  <span>DefaultMutableTreeNode root = ...;
   DefaultTreeModel model = new DefaultTreeModel(root);
   JTree tree = new JTree(model);
   ...
   TreePath selectedPath = tree.getSelectionPath();
   DefaultMutableTreeNode selectedNode =
       ((DefaultMutableTreeNode)selectedPath.getLastPathComponent()).
       getUserObject();</span> </pre>
<span>子类通常只需要覆盖<code>getLastPathComponent</code>和<code>getParentPath</code> 。</span>
<span>由于<code>JTree</code>内部创建了<code>TreePath</code> s的各个点，通常没有用的子类<code>TreePath</code>并与<code>JTree</code>使用。</span>
<p> <span>虽然<code>TreePath</code>是可序列化的，但如果路径的任何元素<code>NotSerializableException</code> ，则会抛出NotSerializableException。</span> </p>
<p> <span>有关使用树路径的更多信息和示例，请参阅<em>Java教程</em>中<em>的</em> <a href="http://docs.oracle.com/javase/tutorial/uiswing/components/tree.html">How to Use Trees</a> <em>。</em></span> </p>
<p> <span><strong>警告：</strong>此类的序列化对象与将来的Swing版本不兼容。</span> <span>当前的序列化支持适用于运行相同版本的Swing的应用程序之间的短期存储或RMI。</span> <span>从1.4开始，对所有JavaBeans的长期存储的支持已经添加到<code>java.beans</code>包中。</span> <span>请参阅<a href="../../../java/beans/XMLEncoder.html" title="java.beans中的类"><code>XMLEncoder</code></a> 。</span> </p>
