std::divides<void>

STD：：分隔<void>

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

std::divides<>是std::divides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()returns the quotient of two arguments (public member function)

std：：divids<>：：Operator%28%29

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

返回除法结果lhs通过rhs%28或其他operator/重载到执行%29。

参数

lhs, rhs-values to divide

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。
