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

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

[edit] Specializations

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

std::bit_xor::operator()

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.

Parameters

lhs, rhs - values to compute bitwise XOR of

Return value

The result of lhs ^ rhs.

Exceptions

(none)

Possible implementation

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