Member Function Documentation

◆ Cancel()

virtual void v8::JobHandle::Cancel ( )
pure virtual

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

◆ CancelAndDetach()

virtual void v8::JobHandle::CancelAndDetach ( )
pure virtual

◆ IsActive()

virtual bool v8::JobHandle::IsActive ( )
pure virtual

Returns true if there's any work pending or any worker running.

◆ IsValid()

virtual bool v8::JobHandle::IsValid ( )
pure virtual

Returns true if associated with a Job and other methods may be called. Returns false after Join() or Cancel() was called. This may return true even if no workers are running and IsCompleted() returns true

◆ Join()

virtual void v8::JobHandle::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 v8::JobHandle::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.

◆ UpdatePriority()

virtual void v8::JobHandle::UpdatePriority ( TaskPriority  new_priority)
inlinevirtual

Update this Job's priority.

◆ UpdatePriorityEnabled()

virtual bool v8::JobHandle::UpdatePriorityEnabled ( ) const
inlinevirtual

Returns true if job priority can be changed.
