|
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.
