Defined in header <experimental/execution_policy>
template< class T > struct is_execution_policy;		(parallelism TS)

Checks whether T is a standard or implementation-defined execution policy type.

Provides the member constant value which is equal to true, if T is execution_policy, sequential_execution_policy, parallel_execution_policy, parallel_vector_execution_policy, or an implementation-defined execution policy type. Otherwise, value is equal to false.

The behavior of a program that adds specializations for is_execution_policy is undefined.

Template parameters

T

-

a type to check

Helper template

Defined in header <experimental/execution_policy>
template< class T > constexpr bool is_execution_policy_v = is_execution_policy<T>::value;		(parallelism TS)

Inherited from std::integral_constant

Member constants

value [static]

true if T is a standard or implementation-defined execution policy 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)
