std::experimental::negation – std::experimental::negation

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 BaseCharacteristic 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
(public static member constant)
[static]

Member functions

converts the object to bool, returns value
operator bool (public member function)

operator() returns value
(public member function)
(C++14)

Member types

Type Definition
value_type bool
type std::integral_constant<bool, value>

Possible implementation

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