Member Function Documentation

◆ GetTaskId()

virtual uint8_t GetTaskId ( )
inlinevirtual

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. TODO(etiennep): Make pure virtual once custom embedders implement it.

Definition at line 180 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.
