Struct template as_expr

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

Synopsis

// In header: <boost/proto/traits.hpp>
template<typename Domain = proto::default_domain> 
struct as_expr :  proto::callable {
  // member classes/structs/unions
  template<typename This, typename T> 
  struct result<This(T)> :  proto::result_of::as_expr< typename remove_reference< T >::type, Domain >
  {
  };
  // public member functions
  template<typename T> 
    typename proto::result_of::as_expr< T, Domain >::type 
    operator()(T &) const;
  template<typename T> 
    typename proto::result_of::as_expr< T const, Domain >::type 
    operator()(T const &) const;
};
