std::experi...al::negation(3)

💖 NAME 💖

std::experimental::negation — std::experimental::negation (the page title up top is std::experi...al::negation(3), and the manual name is C++ Standard Libary, so hi bestie 💅).

✨ Synopsis ✨

Defined in header <experimental/type_traits>
template< class B >                          (1) (library
fundamentals TS v2)
struct negation;

Forms the logical negation of the type trait B.

The type negation<B> is a UnaryTypeTrait with a base characteristic of std::integral_constant<bool, !bool(B::value)>.

🎀 Template parameters 🎀

• B — any type such that the expression bool(B::value) is a valid constant expression.

🦋 Helper variable template 🦋

template< class B >                              (library
fundamentals TS v2)
constexpr bool negation_v = negation<B>::value;

💜 Inherited from std::integral_constant 💜

🌸 Member constants 🌸

• value — true if B has a member ::value such that !bool(B::value) is true, false otherwise. [static] (public static member constant).

🌈 Member functions 🌈

• operator bool — converts the object to bool, returns value (public member function).
• operator() — returns value (C++14) (public member function).

🍓 Member types 🍓

• value_type — bool
• type — std::integral_constant<bool, value>

🔥 Possible implementation 🔥

template<class B>
struct negation : std::integral_constant<bool, !bool(B::value)> {};
