Struct template post_dec

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

Synopsis

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

template<typename T> 
struct post_dec :  proto::transform< post_dec<T> > {
  // types
  typedef proto::expr< proto::tag::post_dec, proto::list1< T > >                               type;         
  typedef 
            proto::basic_expr< proto::tag::post_dec, proto::list1< T > >
           proto_grammar;

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