(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.

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)  |
