  }
  public void setParent(ast.IJSubNode n) {
    parent = n;
  }
  
  public ast.IJSubNode getParent() { 
    return parent; 
  }

  public void addChild(ast.IJSubNode n) {}
  public ast.IJSubNode getChild(int i) { 
    return null; 
  }
  public java.util.Enumeration elements () {
    return null;
  }
  public int getNumChildren() {
