Struct template pre_inc

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


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