38 | // States: |
---|
39 | // G4State_PreInit |
---|
40 | // At the very begining of the Application. G4StateManager starts |
---|
41 | // with this state. G4Initializer changes this state to Init when |
---|
42 | // G4Initializer::Initialize() method starts. At the moment of |
---|
43 | // the state change of PreInit->Init, no material, geometrical, |
---|
44 | // particle or physics process has been initialized. |
---|
45 | // G4State_Init |
---|
46 | // During the G4Initializer::Initialize() method. G4Initializer |
---|
47 | // changes this state to Idle when all initialization procedures |
---|
48 | // are successfully Done. |
---|
49 | // G4State_Idle |
---|
50 | // Ready to start "BeamOn". G4RunManager changes this state to |
---|
51 | // GeomClosed when G4RunManager::BeamOn() method starts and |
---|
52 | // G4GeometryManager::CloseGeometry() is Done. At the end of |
---|
53 | // BeamOn() method, G4RunManager will reset the application state |

54 | // to Idle after G4GeometryManager::OpenGeometry() is Done. |
---|
55 | // G4State_GeomClosed |
---|
56 | // G4 is in this state between G4GeometryManager::CloseGeometry() |
---|
57 | // and G4GeometryManager::OpenGeometry(), but no event is in |
---|
58 | // progress. At the begining of each event (construction of a |
---|
59 | // G4Event object and primary particle generation), G4RunManager |
---|
60 | // changes this state to EventProc and resets to GeomClosed state |
---|
61 | // when G4EventManager::ProcessOneEvent() is over. |
