Struct template logical_and

boost::proto::logical_and — A metafunction for generating logical-and expression types, a grammar element for matching logical-and 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 logical_and :  proto::transform< logical_and<T, U> > {
  // types
  typedef proto::expr< proto::tag::logical_and, proto::list2< T, U > >       type;         
  typedef proto::basic_expr< proto::tag::logical_and, proto::list2< T, U > > proto_grammar;

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