< cpp | utility | functional
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
.
Specializations
The standard library provides a specialization of
|
(since C++14) |
Member types
Type | Definition |
result_type (deprecated in C++17)(removed in C++20)
|
T
|
first_argument_type (deprecated in C++17)(removed in C++20)
|
T
|
second_argument_type (deprecated in C++17)(removed in C++20)
|
T
|
These member types are obtained via publicly inheriting std::binary_function<T, T, T>. |
(until C++11) |
Member functions
operator() |
returns the result of bitwise XOR of two arguments (public member function) |
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
May throw implementation-defined exceptions.
Possible implementation
constexpr T operator()(const T &lhs, const T &rhs) const { return lhs ^ rhs; } |
