33 // Class Description:
34 //
35 // Specifies the state of the G4 application
36 //
37 // States:
38 // G4State_PreInit
39 // At the very begining of the Application. G4StateManager starts
40 // with this state. G4Initializer changes this state to Init when
41 // G4Initializer::Initialize() method starts. At the moment of
42 // the state change of PreInit->Init, no material, geometrical,
43 // particle or physics process has been initialized.
44 // G4State_Init
45 // During the G4Initializer::Initialize() method. G4Initializer
46 // changes this state to Idle when all initialization procedures
47 // are successfully Done.
48 // G4State_Idle
49 // Ready to start "BeamOn". G4RunManager changes this state to
50 // GeomClosed when G4RunManager::BeamOn() method starts and
51 // G4GeometryManager::CloseGeometry() is Done. At the end of
52 // BeamOn() method, G4RunManager will reset the application state
53 // to Idle after G4GeometryManager::OpenGeometry() is Done.
54 // G4State_GeomClosed
55 // G4 is in this state between G4GeometryManager::CloseGeometry()
56 // and G4GeometryManager::OpenGeometry(), but no event is in
57 // progress. At the begining of each event (construction of a
58 // G4Event object and primary particle generation), G4RunManager
59 // changes this state to EventProc and resets to GeomClosed state
60 // when G4EventManager::ProcessOneEvent() is over.
61 // G4State_EventProc
62 // Processing an event.
63 // G4State_Quit
64 // G4 is in this state when the destructor of G4RunManager is invoked.
65 // G4State_Abort
66 // G4 is in this state when G4Exception is invoked.
