Struct template negate

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

Synopsis

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

template<typename T> 
struct negate :  proto::transform< negate<T> > {
  // types
  typedef proto::expr< proto::tag::negate, proto::list1< T > > type;           
  typedef type                                                 proto_base_expr;

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