    • head

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

      The node may be modified (for example via Node.attr(String)), removed with Node.remove(), or replaced with Node.replaceWith(Node). If the node is an Element, you may cast it and access those methods.

      Traversal uses a forward cursor. After head() completes:

      • If the current node is still attached, traversal continues into its current children and then its following siblings. Nodes inserted before the current node are not visited.
      • If the current node was detached and another node now occupies its former sibling position, the node now at that position is not passed to head() again. Traversal continues from there: its children are visited, then the node is passed to NodeVisitor.tail(Node, int), then later siblings are visited.
      • If the current node was detached and no node occupies its former sibling position, the current node is not passed to tail(), and traversal resumes at the node that originally followed it.

      Traversal never advances outside the original root subtree. If the traversal root is detached during head(), traversal stops at the original root boundary.

      Specified by:
      head in interface NodeVisitor
      Parameters:
      source - 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 source, 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 defaults to a no-op.

      The node passed to tail() is the node at the current traversal position when the subtree completes. If head() replaced the original node, this may be the replacement node instead.

      Structural changes to the current node are not supported during tail().

      Specified by:
      tail in interface NodeVisitor
      Parameters:
      source - 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.
