std::bit_xor: std::bit_xor


std::bit_xor - std::bit_xor


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

Function object for performing bitwise XOR. Effectively calls operator^ on type T.


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

              function object implementing x ^ y deducing argument and return types (since C++14)

Member functions

           returns the result of bitwise XOR of two arguments
operator() (public member function)


T operator()( const T& lhs, const T& rhs ) const; (until C++14)
constexpr T operator()( const T& lhs, const T& rhs ) const; (since C++14)

Returns the result of bitwise XOR of lhs and rhs.


lhs, rhs - values to compute bitwise XOR of

Return value

The result of lhs ^ rhs.



Possible implementation

  constexpr T operator()(const T &lhs, const T &rhs) const
      return lhs ^ rhs;
