<span>此接口表示树组件选择的当前状态。</span>
<span>有关使用树选择模型的信息和示例，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> <span>树选择的状态由一组TreePaths和可选的一组整数表征。</span> <span>从TreePath到整数的映射是通过RowMapper的一个实例来完成的。</span> <span>TreeSelectionModel没有必要使RowMapper正确运行，但没有RowMapper <code>getSelectionRows</code>将返回null。</span> </p>
<p> <span>可以将TreeSelectionModel配置为仅允许一个路径（ <code>SINGLE_TREE_SELECTION</code> ）多个连续路径（ <code>CONTIGUOUS_TREE_SELECTION</code> ）或多个不连续路径（ <code>DISCONTIGUOUS_TREE_SELECTION</code> ）。</span> <span>A <code>RowMapper</code>用于确定TreePath是否是连续的。</span> <span>在没有RowMapper <code>CONTIGUOUS_TREE_SELECTION</code>和<code>DISCONTIGUOUS_TREE_SELECTION</code>行为相同的情况下，就是它们允许在TreeSelectionModel中包含任意数量的路径。</span> </p>
<p> <span>对于选择模型<code>CONTIGUOUS_TREE_SELECTION</code>的路径被变更的任何时间（ <code>setSelectionPath</code> ， <code>addSelectionPath</code> ...）的TreePath，则再次检查，以他们是连续的。</span> <span>还可以通过调用<code>resetRowSelection</code>来强制对<code>resetRowSelection</code> 。</span> <span>一组不连贯的TreePath如何映射到一个连续的集合是由这个接口的实现者执行一个特定的策略。</span> </p>
<p> <span>实现应该将添加到选择中的重复TreePath组合起来。</span> <span>例如，以下代码</span> </p>
<pre>  <span>TreePath[] paths = new TreePath[] { treePath, treePath };
   treeSelectionModel.setSelectionPaths(paths);</span> </pre>
<span>应该只能选择一个路径： <code>treePath</code> ，而不是<code>treePath</code>两个<code>treePath</code> 。</span>
<p> <span>引导TreePath是添加（或设置）的最后一个路径。</span> <span>那么引导行就是从RowMapper确定的对应于TreePath的行。</span> </p>
