40 // Class Description:
41 //
42 // Class responsible for handling and updating the running state
43 // of the Geant4 application during its different phases.
44 // The class is a singleton, it can be accessed via the public
45 // method G4StateManager::GetStateManager().
46 //
47 // States of Geant4 are defined in G4ApplicationState.
