Struct template less

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


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

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

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