Member Function Documentation

◆ Cancel()

virtual void Cancel ( )
pure virtual

Forces all existing workers to yield ASAP. Waits until they have all returned from the Job's callback before returning.

◆ IsRunning()

virtual bool IsRunning ( )
pure virtual

Returns true if associated with a Job and other methods may be called. Returns false after Join() or Cancel() was called.

◆ Join()

virtual void Join ( )
pure virtual

Contributes to the job on this thread. Doesn't return until all tasks have completed and max concurrency becomes 0. When Join() is called and max concurrency reaches 0, it should not increase again. This also promotes this Job's priority to be at least as high as the calling thread's priority.

◆ NotifyConcurrencyIncrease()

virtual void NotifyConcurrencyIncrease ( )
pure virtual

Notifies the scheduler that max concurrency was increased, and the number of worker should be adjusted accordingly. See Platform::PostJob() for more details.
