      • head

        public void head​(Node node,
                         int depth)
        Description copied from interface: NodeVisitor
        Callback for when a node is first visited.

        The node may be modified (e.g. Node.attr(String), replaced Node.replaceWith(Node)) or removed Node.remove(). If it's instanceOf Element, you may cast it to an Element and access those methods.

        Specified by:
        head in interface NodeVisitor
        Parameters:
        node - the node being visited.
        depth - the depth of the node, relative to the root node. E.g., the root node has depth 0, and a child node of that will have depth 1.
      • tail

        public void tail​(Node node,
                         int depth)
        Description copied from interface: NodeVisitor
        Callback for when a node is last visited, after all of its descendants have been visited.

        This method has a default no-op implementation.

        Note that neither replacement with Node.replaceWith(Node) nor removal with Node.remove() is supported during tail().

        Specified by:
        tail in interface NodeVisitor
        Parameters:
        node - the node being visited.
        depth - the depth of the node, relative to the root node. E.g., the root node has depth 0, and a child node of that will have depth 1.
