  • Method Details

    • jjtOpen

      void jjtOpen()
      This method is called after the node has been made the current node. It indicates that child nodes can now be added to it.

    • jjtClose

      void jjtClose()
      This method is called after all the child nodes have been added.

    • jjtSetParent

      void jjtSetParent(Node n)
      This pair of methods are used to inform the node of its parent.

    • jjtGetParent

      Node jjtGetParent()

    • jjtAddChild

      void jjtAddChild(Node n, int i)
      This method tells the node to add its argument to the node's list of children.

    • jjtGetChild

      Node jjtGetChild(int i)
      This method returns a child node. The children are numbered from zero, left to right.

    • jjtGetNumChildren

      int jjtGetNumChildren()
      Return the number of children the node has.
