28// Class description:
29//
30// This is a class for mandatory control of the Geant4 kernel.
31// This class implements Worker behavior in a MT application.
32//
33// This class is constructed by G4MTRunManager. If a user uses his/her own
34// class instead of G4MTRunManager, this class must be instantiated by at the
35// very beginning of the application and must be deleted at the very end.
36// Also, the following methods must be invoked in the proper order:
37// DefineWorldVolume()
38// InitializePhysics()
39// RunInitialization()
40// RunTermination()
41//
42// User must provide his/her own classes derived from the following
43// abstract class and register it to the RunManagerKernel:
44// G4VUserPhysicsList - Particle types, Processes and Cuts
45//
46// G4MTRunManagerKernel does not have an event loop. Handling of events
47// is managed by G4RunManager.
48//
49// This class re-implements only the methods that require special treatment
50// to implement worker behavior
