C++ (Cpp) Monitor::notify_all Examples

Example #1

File: workgroup.cpp Project: netroby/jdk9-dev

  void worker_done_with_task() {
    MonitorLockerEx ml(_monitor, Mutex::_no_safepoint_check_flag);

    _finished++;

    if (_finished == _num_workers) {
      // This will wake up all workers and not only the coordinator.
      _monitor->notify_all();
    }
  }

Example #2

File: dirtyCardQueue.cpp Project: lmsf/jdk9-dev

void FreeIdSet::release_par_id(uint id) {
  MutexLockerEx x(_mon, Mutex::_no_safepoint_check_flag);
  assert(_ids[id] == claimed, "Precondition.");
  _ids[id] = _hd;
  _hd = id;
  _claimed--;
  if (_waiters > 0) {
    _mon->notify_all();
  }
}

Example #3

File: workgroup.cpp Project: 4T-Shirt/OpenJDK-Research

void FreeIdSet::set_safepoint(bool b) {
  _safepoint = b;
  if (b) {
    for (int j = 0; j < NSets; j++) {
      if (_sets[j] != NULL && _sets[j]->_waiters > 0) {
        Monitor* mon = _sets[j]->_mon;
        mon->lock_without_safepoint_check();
        mon->notify_all();
        mon->unlock();
      }
    }
  }
}

Example #4

File: workgroup.cpp Project: netroby/jdk9-dev

  void coordinator_execute_on_workers(AbstractGangTask* task, uint num_workers) {
    MutexLockerEx ml(_monitor, Mutex::_no_safepoint_check_flag);

    _task        = task;
    _num_workers = num_workers;

    // Tell the workers to get to work.
    _monitor->notify_all();

    // Wait for them to finish.
    while (_finished < _num_workers) {
      _monitor->wait(/* no_safepoint_check */ true);
    }

    _task        = NULL;
    _num_workers = 0;
    _started     = 0;
    _finished    = 0;
  }
