26 // G4ApplicationState
27 //
28 // Description:
29 //
30 // Specifies the state of the G4 application
31 //
32 // States:
33 // G4State_PreInit
34 // At the very beginning of the Application. G4StateManager starts
35 // with this state. G4Initializer changes this state to Init when
36 // G4Initializer::Initialize() method starts. At the moment of
37 // the state change of PreInit->Init, no material, geometrical,
38 // particle or physics process has been initialized.
39 // G4State_Init
40 // During the G4Initializer::Initialize() method. G4Initializer
41 // changes this state to Idle when all initialization procedures
42 // are successfully Done.
43 // G4State_Idle
44 // Ready to start "BeamOn". G4RunManager changes this state to
45 // GeomClosed when G4RunManager::BeamOn() method starts and
46 // G4GeometryManager::CloseGeometry() is Done. At the end of
47 // BeamOn() method, G4RunManager will reset the application state
48 // to Idle after G4GeometryManager::OpenGeometry() is Done.
49 // G4State_GeomClosed
50 // Geant4 is in this state between G4GeometryManager::CloseGeometry()
51 // and G4GeometryManager::OpenGeometry(), but no event is in
52 // progress. At the begining of each event (construction of a
53 // G4Event object and primary particle generation), G4RunManager
54 // changes this state to EventProc and resets to GeomClosed state
55 // when G4EventManager::ProcessOneEvent() is over.
56 // G4State_EventProc
57 // Processing an event.
58 // G4State_Quit
59 // Geant4 is in this state when the destructor of G4RunManager is invoked.
60 // G4State_Abort
61 // Geant4 is in this state when G4Exception is invoked.
