Member Function Documentation

GetTaskId()

virtual uint8_t v8::JobDelegate::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 v8::JobDelegate::IsJoiningThread ( ) const

pure virtual

Returns true if the current task is called from the thread currently running JobHandle::Join().

NotifyConcurrencyIncrease()

virtual void v8::JobDelegate::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 v8::JobDelegate::ShouldYield ( )

pure virtual

Returns true if this thread must return from the worker task on the current thread ASAP. Workers should periodically invoke ShouldYield (or YieldIfNeeded()) as often as is reasonable. After this method returned true, ShouldYield must not be called again.
