Struct template plus

boost::proto::plus — A metafunction for generating binary plus expression types, a grammar element for matching binary plus expressions, and a PrimitiveTransform that dispatches to the proto::pass_through<> transform.

Synopsis

// In header: <boost/proto/traits.hpp>

template<typename T, typename U> 
struct plus :  proto::transform< plus<T, U> > {
  // types
  typedef proto::expr< proto::tag::plus, proto::list2< T, U > >       type;         
  typedef proto::basic_expr< proto::tag::plus, proto::list2< T, U > > proto_grammar;

  // member classes/structs/unions
  template<typename Expr, typename State, typename Data> 
  struct impl :  proto::pass_through<plus>::template impl<Expr, State, Data> {
  };
};
