      • HtmlTreeModel

        public HtmlTreeModel​(NodeList root)
        Create an HTML tree view.
        Parameters:
        root - The nodes at the root of the tree (the nodes are wrapped in an Html node that is never seen because it's the root, but this makes all downstream processing super-simple because every tree node is then a Node, not sometimes a NodeList at the root).
