NAME¶

std::experimental::is_simd_flag_type - std::experimental::is_simd_flag_type

Synopsis¶

Defined in header <experimental/simd>
template< class T > (parallelism TS v2)
struct is_simd_flag_type;

If T is a valid type for the second argument to copy_from, copy_to or the
corresponding load constructors of simd or simd_mask, provides the member constant
value equal true. For any other type, value is false.

Template parameters¶

T - a type to check

Helper variable template

template< class T >
inline constexpr bool is_simd_flag_type_v = (parallelism TS v2)
is_simd_flag_type<T>::value;

Inherited from std::integral_constant

Member constants¶

value true if T is a load/store flag tag type, 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¶

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

Example¶

// Run this code

#include <experimental/simd>
#include <iostream>

int main()
{
namespace stdx = std::experimental;
std::cout << std::boolalpha
<< stdx::is_simd_flag_type_v<stdx::element_aligned_tag> << '\n'
<< stdx::is_simd_flag_type_v<int> << '\n';
}

Output:¶

true
false
