  template<typename This, typename Expr> 
  struct result<This(Expr)> :  proto::result_of::right< Expr > {
  };

  // public member functions
  template<typename Expr> 
    typename proto::result_of::right< Expr & >::type operator()(Expr &) const;
  template<typename Expr> 
    typename proto::result_of::right< Expr const & >::type 
    operator()(Expr const &) const;
};

Description

right public member functions

  1. template<typename Expr> 
      typename proto::result_of::right< Expr & >::type 
      operator()(Expr & expr) const;

    Return the right child of the given binary expression.

    Parameters:

    expr

    The expression node.

    Requires:

    proto::is_expr<Expr>::value is true

    2 == Expr::proto_arity::value

    Returns:

    proto::right(expr)

    Throws:

    Will not throw.
  2. template<typename Expr> 
      typename proto::result_of::right< Expr const & >::type 
      operator()(Expr const & expr) const;
