michael@0: // SandboxFactory is a set of static methods to get access to the broker
michael@0: // or target services object. Only one of the two methods (GetBrokerServices,
michael@0: // GetTargetServices) will return a non-null pointer and that should be used
michael@0: // as the indication that the process is the broker or the target:
michael@0: //
michael@0: // BrokerServices* broker_services = SandboxFactory::GetBrokerServices();
michael@0: // if (NULL != broker_services) {
michael@0: //   //we are the broker, call broker api here
michael@0: //   broker_services->Init();
michael@0: // } else {
michael@0: //   TargetServices* target_services = SandboxFactory::GetTargetServices();
michael@0: //   if (NULL != target_services) {
michael@0: //    //we are the target, call target api here
michael@0: //    target_services->Init();
michael@0: //  }
michael@0: //
michael@0: // The methods in this class are expected to be called from a single thread
michael@0: //
michael@0: // The Sandbox library needs to be linked against the main executable, but
michael@0: // sometimes the API calls are issued from a DLL that loads into the exe
michael@0: // process. These factory methods then need to be called from the main
michael@0: // exe and the interface pointers then can be safely passed to the DLL where
michael@0: // the Sandbox API calls are made.
