Struct template logical_not

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

Synopsis

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

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

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