Struct template dereference

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


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

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

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