  10 // SandboxFactory is a set of static methods to get access to the broker
  11 // or target services object. Only one of the two methods (GetBrokerServices,
  12 // GetTargetServices) will return a non-null pointer and that should be used
  13 // as the indication that the process is the broker or the target:
  14 //
  15 // BrokerServices* broker_services = SandboxFactory::GetBrokerServices();
  16 // if (NULL != broker_services) {
  17 //   //we are the broker, call broker api here
  18 //   broker_services->Init();
  19 // } else {
  20 //   TargetServices* target_services = SandboxFactory::GetTargetServices();
  21 //   if (NULL != target_services) {
  22 //    //we are the target, call target api here
  23 //    target_services->Init();
  24 //  }
  25 //
  26 // The methods in this class are expected to be called from a single thread
  27 //
  28 // The Sandbox library needs to be linked against the main executable, but
  29 // sometimes the API calls are issued from a DLL that loads into the exe
  30 // process. These factory methods then need to be called from the main
  31 // exe and the interface pointers then can be safely passed to the DLL where
  32 // the Sandbox API calls are made.
