C++ (Cpp) CallbackHandle::isValid Examples

Example #1

File: thread_pool_task_executor.cpp Project: Ferryworld/mongo

void ThreadPoolTaskExecutor::wait(const CallbackHandle& cbHandle) {
    invariant(cbHandle.isValid());
    auto cbState = checked_cast<CallbackState*>(getCallbackFromHandle(cbHandle));
    if (cbState->isFinished.load()) {
        return;
    }
    stdx::unique_lock<stdx::mutex> lk(_mutex);
    if (!cbState->finishedCondition) {
        cbState->finishedCondition.emplace();
    }
    while (!cbState->isFinished.load()) {
        cbState->finishedCondition->wait(lk);
    }
}

Example #2

File: thread_pool_task_executor.cpp Project: qihsh/mongo

void ThreadPoolTaskExecutor::cancel(const CallbackHandle& cbHandle) {
    invariant(cbHandle.isValid());
    auto cbState = checked_cast<CallbackState*>(getCallbackFromHandle(cbHandle));
    stdx::unique_lock<stdx::mutex> lk(_mutex);
    cbState->canceled.store(1);
    if (cbState->isNetworkOperation) {
        lk.unlock();
        _net->cancelCommand(cbHandle);
        return;
    }
    if (cbState->readyDate != Date_t{}) {
        // This callback might still be in the sleeper queue; if it is, schedule it now
        // rather than when the alarm fires.
        auto iter = std::find_if(_sleepersQueue.begin(),
                                 _sleepersQueue.end(),
                                 [cbState](const std::shared_ptr<CallbackState>& other) {
                                     return cbState == other.get();
                                 });
        if (iter != _sleepersQueue.end()) {
            invariant(iter == cbState->iter);
            scheduleIntoPool_inlock(&_sleepersQueue, cbState->iter);
        }
    }
