Struct template pre_dec

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

Synopsis

template<typename T> 
struct pre_dec :  proto::transform< pre_dec<T> > {
  // types
  typedef proto::expr< proto::tag::pre_dec, proto::list1< T > > type;           
  typedef type                                                  proto_base_expr;
  template<typename Expr, typename State, typename Data> 
  struct impl :
     proto::pass_through<pre_dec>::template impl<Expr, State, Data>
  {
  };
};
