// Abstract interface for GEANT4 Global Fast Simulation Manager.

|
// Class description:
|
|
//
|
|
// G4GlobalFastSimulationManager is a "Singleton", i.e., only one instance
|
|
// of it may exist. This is ensured by making the constructor private.
|
|
//
|
|
// G4VGlobalFastSimulationManager is an abstract interface for the
|
|
// G4GlobalFastSimulationManager one. It has the public access function
|
|
// GetConcreteInstance(), which is used to obtain a pointer to the concrete
|
|
// G4GlobalFastSimulationManager, should it exist. After
|
|
//
|
|
// G4VGlobalFastSimulationManager* pVFSMan =
|
|
// G4VGlobalFastSimulationManager::GetConcreteInstance ();
|
|
//
|
|
// pVFSMan points to the real (concrete) G4GlobalFastSimulationManager if
|
|
// at least a parameterisation envelope exists, otherwise is zero.
|
|
//
|
|
// Thus all code must be protected, for example by:
|
|
// if (pVFSMan)
|
|
// G4FlavoredParallelWorld* =
|
|
// pVFSMan -> GetFlavoredWorldForThis(p);
