std::bit_xor<void>

STD：BIT[医]异或<void>

Defined in header ​​
template<> class bit_xor<void>;​(since C++14)

std::bit_xor<>是std::bit_xor并推导出参数和返回类型。

成员类型

Member typeDefinition
is_transparent/* unspecified */

成员函数

operator()applies operator^ to lhs and rhs (public member function)

STD：BIT[医]XOR<>：：运算符%28%29

template< class T, class U> constexpr auto operator()( T&& lhs, U&& rhs ) const -> decltype(std::forward(lhs) ^ std::forward(rhs)​​

返回lhs ^ rhs...

参数

lhs, rhs-values to compute bitwise XOR for

返回值

结果lhs ^ rhs...

注记

成员类型is_transparent向调用方指示此函数对象是透明FunctionObject：它接受任意类型的参数，并使用完美的转发，这避免了在异构上下文中使用函数对象或使用rvalue参数时不必要的复制和转换。特别是模板函数，例如std::set::find和std::set::lower_bound在它们的Compare类型。
