  • Method Details

    • parent

      Node parent()
      Return the Node that contains (and created) this Node.

    • id

      int id()
      Return the unique ID of this node. This starts at 1 and is incremented for each new Node that is created.

    • parent

      void parent(Node node)
      Set the parent to a new value. Should only be called inside NodeBase.

    • getAncestor

      <T extends Node> T getAncestor(Class<T> type)
      Return the first ancestor of this node of the given type, if any. Throws IllegalArgumentException if not found.

    • copy

      <T extends Node> T copy(Class<T> cls)
      Make a deep copy of this node. If nn = n.copy(), then n.parent() == nn.parent(), which also means that the parent is NOT copied.

    • copy

      <T extends Node> T copy(Node newParent, Class<T> cls)
      Copy setting a new parent in the result.

    • accept

      void accept(Visitor visitor)
      Accept the visitor and allow it to perform actions on this Node.
