Member Function Documentation

GetTaskId()

virtual uint8_t GetTaskId ( )

pure virtual

Returns a task_id unique among threads currently running this job, such that GetTaskId() < worker count. To achieve this, the same task_id may be reused by a different thread after a worker_task returns.

IsJoiningThread()

virtual bool IsJoiningThread ( ) const

inlinevirtual

Returns true if the current task is called from the thread currently running JobHandle::Join(). TODO(etiennep): Make pure virtual once custom embedders implement it.

Definition at line 186 of file v8-platform.h.

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.

ShouldYield()

virtual bool ShouldYield ( )

pure virtual

Returns true if this thread should return from the worker task on the current thread ASAP. Workers should periodically invoke ShouldYield (or YieldIfNeeded()) as often as is reasonable.
