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