std::equal_to<void>

性病：平等[医]到<void>

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

std::equal_to<>是std::equal_to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()tests if the two arguments compare equal (public member function)

性病：平等[医]to<>：：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)​​

之间的相等比较的结果。lhs和rhs...

参数

lhs, rhs-values to compare

返回值

结果std::forward<T>(lhs)==std::forward<U>(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。
