C++ (Cpp) TaskPtr::setScheduled Examples

Example #1

File: thread_group.cpp Project: cogsys-tuebingen/csapex

void ThreadGroup::schedule(TaskPtr task)
{
    apex_assert_hard(!destroyed_);

    std::unique_lock<std::recursive_mutex> tasks_lock(tasks_mtx_);

    if (!tasks_.empty()) {

            if (t.get() == task.get()) {
                return;
            }
        }
    }

    tasks_.insert(task);

    task->setScheduled(true);

    work_available_.notify_all();
}
