Member Function Documentation

GetMaxConcurrency()

size_t v8::internal::Sweeper::MajorSweeperJob::GetMaxConcurrency ( size_t worker_count ) const

inlineoverridevirtual

Controls the maximum number of threads calling Run() concurrently, given the number of threads currently assigned to this job and executing Run(). Run() is only invoked if the number of threads previously running Run() was less than the value returned. In general, this should return the latest number of incomplete work items (smallest unit of work) left to process, including items that are currently in progress. |worker_count| is the number of threads currently assigned to this job which some callers may need to determine their return value. Since GetMaxConcurrency() is a leaf function, it must not call back any JobHandle methods.

Implements v8::JobTask.
