std::bit_not: std::bit_not

NAME

std::bit_not - std::bit_not

Synopsis


Defined in header <functional>
template< class T = void > (since C++14)
struct bit_not;


Function object for performing bitwise NOT. Effectively calls operator~ on type T.

Specializations


The standard library provides a specialization of std::bit_not when T is not specified, which leaves the parameter types and return type to be deduced.


              function object implementing ~x deducing argument and return types
bit_not<void> (class template specialization)

Member types


                                              (until C++20)
Type Definition
result_type(deprecated in C++17) T
argument_type(deprecated in C++17) T

Member functions


           returns the result of bitwise NOT of its argument
operator() (public member function)


 std::bit_not::operator()


constexpr T operator()( const T& arg ) const;


Returns the result of bitwise NOT of arg.

Parameters


arg - value to compute bitwise NOT of

Return value


The result of ~arg.

Exceptions


(none)

Possible implementation


  constexpr T operator()(const T& arg) const
  {
      return ~arg;
  }
