std::experimental::is_simd_flag_type

< cpp‎ | experimental‎ | simd

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

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

a type to check

Helper variable template

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

Inherited from std::integral_constant

Member constants

value

[static]

true if T is a load/store flag tag type , false otherwise
(public static member constant)

Member functions

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

Member types

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

Example

#include <experimental/simd>
#include <iostreams>
 
int main() 
{
    namespace stdx = std::experimental;
    std::cout << stdx::is_simd_flag_type_v<stdx::element_aligned_tag> << '\n';
    std::cout << stdx::is_simd_flag_type_v<int> << '\n';
}

Output:

true
false
