      <R, D> R accept(TreeVisitor<R,D> visitor, D data)
      Accept method used to implement the visitor pattern. The visitor pattern is used to implement operations on trees.
      Type Parameters:
      R - the result type of this operation
      D - the type of additional data
      visitor - the visitor to be called
      data - a value to be passed to the visitor
      the result returned from calling the visitor
