30 // Abstract interface for GEANT4 Global Fast Simulation Manager.
31 // P. Mora de Freitas & M. Verderi 14/April/1999.
32 //
33 // Class description:
34 //
35 // G4GlobalFastSimulationManager is a "Singleton", i.e., only one instance
36 // of it may exist. This is ensured by making the constructor private.
37 //
38 // G4VGlobalFastSimulationManager is an abstract interface for the
39 // G4GlobalFastSimulationManager one. It has the public access function
40 // GetConcreteInstance(), which is used to obtain a pointer to the concrete
41 // G4GlobalFastSimulationManager, should it exist. After
42 //
43 // G4VGlobalFastSimulationManager* pVFSMan =
44 // G4VGlobalFastSimulationManager::GetConcreteInstance ();
45 //
46 // pVFSMan points to the real (concrete) G4GlobalFastSimulationManager if
47 // at least a parameterisation envelope exists, otherwise is zero.
48 //
49 // Thus all code must be protected, for example by:
50 // if (pVFSMan)
51 // G4FlavoredParallelWorld* =
52 // pVFSMan -> GetFlavoredWorldForThis(p);
