Struct template as_child

boost::proto::functional::as_child — A callable PolymorphicFunctionObject that is equivalent to the proto::as_child() function.

Synopsis

template<typename Domain = proto::default_domain> 
struct as_child :  proto::callable {
  template<typename This, typename T> 
  struct result<This(T)> :  proto::result_of::as_child< T, Domain > {
  };

  // public member functions
  template<typename T> 
    typename proto::result_of::as_child< T, Domain >::type 
    operator()(T &) const;
  template<typename T> 
    typename proto::result_of::as_child< T const, Domain >::type 
    operator()(T const &) const;
};

Description

as_child public member functions

  1. template<typename T> 
      typename proto::result_of::as_child< T, Domain >::type 
      operator()(T & t) const;

    Wrap an object in a Proto terminal if it isn't a Proto expression already.

    Parameters:

    t

    The object to wrap.

    Returns:

    proto::as_child<Domain>(t)

  2. template<typename T> 
      typename proto::result_of::as_child< T const, Domain >::type 
      operator()(T const & t) const;

    This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
