java - 如何将 Swing TreeNode 转换为 Apache Tobago TreePath？

Question

我有一个 Swing TreeNode (DefaultMutableTreeNode)，并且必须为每个 Swing TreeNode 生成一个 Apache Tobago TreePath:

Swing 树:

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

Apache 多巴哥树路径:

[]
    [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，我们将不胜感激。

例如这样的事情:

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);
}
