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