如何将Swing TreeNode转换为Apache多巴哥TreePath？

Question

我有一个Swing TreeNode (DefaultMutableTreeNode)，必须为每个Swing TreeNode生成一个Apache多巴哥TreePath：

秋千树：

Root
    Node1
        Child11
        Child12
        Child13
    Node2
        Child21
        Child22
        Child23
    Node3
        Child31
        Child32
        Child33

阿帕奇多巴哥TreePath：

[]
    [0]
        [0,0]
        [0,1]
        [0,2]
    [1]
        [1,0]
        [1,1]
        [1,2]
    [2]
        [2,0]
        [2,1]
        [2,2]

示例：

  Input:  Child11
  Output: [0,1]

如有任何建议，将不胜感激。

提前谢谢托马斯

例如，如下所示：

public static org.apache.myfaces.tobago.model.TreePath convertPath(TreeNode node) {
    List<Integer> list = new ArrayList<>();
    TreeNode current = node;
    while (current.getParent() != null) {
        list.add(0, current.getParent().getIndex(current));
        current = current.getParent();
    }
    return new org.apache.myfaces.tobago.model.TreePath(list);
}
