C++ (Cpp) registrationGuard Examples

Example #1

File: NativeToJsBridge.cpp Project: K-Leon/react-native

JSExecutor* NativeToJsBridge::getExecutor(const ExecutorToken& executorToken) {
  std::lock_guard<std::mutex> registrationGuard(m_registrationMutex);
  auto it = m_executorMap.find(executorToken);
  if (it == m_executorMap.end()) {
    return nullptr;
  }
  return it->second.executor_.get();
}

Example #2

File: Bridge.cpp Project: 271845221/react-native

MessageQueueThread* Bridge::getMessageQueueThread(const ExecutorToken& executorToken) {
  std::lock_guard<std::mutex> registrationGuard(m_registrationMutex);
  auto it = m_executorMap.find(executorToken);
  if (it == m_executorMap.end()) {
    return nullptr;
  }
  return it->second->messageQueueThread_.get();
}

Example #3

File: NativeToJsBridge.cpp Project: K-Leon/react-native

ExecutorToken NativeToJsBridge::registerExecutor(
    ExecutorToken token,
    std::unique_ptr<JSExecutor> executor,
    std::shared_ptr<MessageQueueThread> messageQueueThread) {
  std::lock_guard<std::mutex> registrationGuard(m_registrationMutex);

  CHECK(m_executorTokenMap.find(executor.get()) == m_executorTokenMap.end())
      << "Trying to register an already registered executor!";

  m_executorTokenMap.emplace(executor.get(), token);
  m_executorMap.emplace(
      token,
      ExecutorRegistration(std::move(executor), messageQueueThread));

  return token;
}

Example #4

File: Bridge.cpp Project: 271845221/react-native

ExecutorToken Bridge::registerExecutor(
    std::unique_ptr<JSExecutor> executor,
    std::shared_ptr<MessageQueueThread> messageQueueThread) {
  auto token = m_executorTokenFactory->createExecutorToken();

  std::lock_guard<std::mutex> registrationGuard(m_registrationMutex);

  CHECK(m_executorTokenMap.find(executor.get()) == m_executorTokenMap.end())
      << "Trying to register an already registered executor!";

  m_executorTokenMap.emplace(executor.get(), token);
  m_executorMap.emplace(
      token,
      folly::make_unique<ExecutorRegistration>(std::move(executor), std::move(messageQueueThread)));

  return token;
}

Example #5

File: NativeToJsBridge.cpp Project: K-Leon/react-native

std::unique_ptr<JSExecutor> NativeToJsBridge::unregisterExecutor(JSExecutor& executor) {
  std::unique_ptr<JSExecutor> ret;

  {
    std::lock_guard<std::mutex> registrationGuard(m_registrationMutex);

    auto it = m_executorTokenMap.find(&executor);
    CHECK(it != m_executorTokenMap.end())
        << "Trying to unregister an executor that was never registered!";
    auto it2 = m_executorMap.find(it->second);
    ret = std::move(it2->second.executor_);

    m_executorTokenMap.erase(it);
    m_executorMap.erase(it2);
  }

  return ret;
}

Example #6

File: Bridge.cpp Project: 271845221/react-native

std::unique_ptr<JSExecutor> Bridge::unregisterExecutor(ExecutorToken executorToken) {
  std::unique_ptr<JSExecutor> executor;

  {
    std::lock_guard<std::mutex> registrationGuard(m_registrationMutex);

    auto it = m_executorMap.find(executorToken);
    CHECK(it != m_executorMap.end())
        << "Trying to unregister an executor that was never registered!";

    executor = std::move(it->second->executor_);
    m_executorMap.erase(it);
    m_executorTokenMap.erase(executor.get());
  }

  m_callback->onExecutorUnregistered(executorToken);

  return executor;
}

Example #7

File: NativeToJsBridge.cpp Project: K-Leon/react-native

ExecutorToken NativeToJsBridge::getTokenForExecutor(JSExecutor& executor) {
  std::lock_guard<std::mutex> registrationGuard(m_registrationMutex);
  return m_executorTokenMap.at(&executor);
}
