Android12 Vehicle Hal_android源码中vehiclehal

Set

1. VehicleHalManager::set
2. EmulatedVehicleHal::set
3. VehicleHalClient::setProperty VehicleHalClient实际是VehicleConnector对象，最后会调用VehicleServer的onSetProperty
4. VehicleServer::onSetProperty
5. EmulatedVehicleHal::onPropertyValue
   VehicleEmulator::doSetValueFromClient 此处可以适配通讯协议，通知其他
   EmulatedVehicleHal::doHalEvent
   doHalEvent会调用到VehicleHalManager::onHalEvent,最终由BatchingConsumer取出该事件，回调给上层

Get

1. VehicleHalManager::get -> mHal->get(requestedPropValue, &status);
2. EmulatedVehicleHal::get -> auto internalPropValue = mPropStore->readValueOrNull(requestedPropValue); 最终从PropStore中获取数据
