如何设置节点是分支还是叶子？
我有一棵由数组集合填充的树。我无法控制数组集合中的数据，即使节点没有子节点，它仍然具有“子节点”属性，导致我的树将每个节点视为分支。我可以对 Children 属性中数组的长度进行简单检查。如果这是 0，我需要树将节点显示为叶子，没有公开图标。关于如何实现这一目标有什么想法吗？如果有像 iconFunction 和 labelFunction 这样的branchFunction 就好了。
提前致谢
I have a tree being populated by an array collection. I don't have control of the data in the array collection and even when a node has no children it still has a "children" property that is causing my tree to treat every node as branch. I can do a simple check on the length of the array in the children property. If this is 0 I need the tree to display the node as a leaf, no disclosure icon. Any thoughts on how I can achieve this? It would be nice if there were a branchFunction like the iconFunction and labelFunction.
Thanks in advance

有一个 dataDescriptor 属性，允许您提供一个类来确定如何解析节点和分支。您将需要实现 ITreeDataDescriptor 或 ITreeDataDescriptor2 接口。
There is a dataDescriptor property that allows you to provide a class to determine how nodes and branches are parsed. You will need to implement the ITreeDataDescriptor or ITreeDataDescriptor2 interface.
