bit_xor Function
A predefined function object that performs the bitwise XOR operation (binary operator^) on its arguments.
template<class Type = void>
struct bit_xor : public binary_function< Type, Type, Type > {
Type operator()(
const Type& Left,
const Type& Right
) const;
};
// specialized transparent functor for operator^
template<>
struct bit_xor<void>
{
template<class Type1, class Type2>
auto operator()(Type1&& Left, Type2&& Right) const
-> decltype(std::forward<Type1>(Left)
^ std::forward<Type2>(Right));
};
Parameters
Type, Type1, Type2
Any type that supports an operator^ that takes operands of the specified or inferred types.Left
The left operand of the bitwise XOR operation. The unspecialized template takes an lvalue reference argument of type Type. The specialized template does perfect forwarding of lvalue and rvalue reference arguments of inferred type Type1.Right
The right operand of the bitwise XOR operation. The unspecialized template takes an lvalue reference argument of type Type. The specialized template does perfect forwarding of lvalue and rvalue reference arguments of inferred type Type2.
Return Value
The result of Left^Right. The specialized template does perfect forwarding of the result, which has the type that's returned by operator^.
Remarks
The bit_xor functor is restricted to integral types for the basic data types, or to user-defined types that implement binary operator^.
