// Class Description:
|
|
//
|
|
// Specifies the state of the G4 application
|
|
//
|
|
// States:
|
|
// PreInit
|
|
// At the very begining of the Application. G4StateManager starts
|
|
// with this state. G4Initializer changes this state to Init when
|
|
// G4Initializer::Initialize() method starts. At the moment of
|
|
// the state change of PreInit->Init, no material, geometrical,
|
|
// particle or physics process has been initialized.
|
|
// Init
|
|
// During the G4Initializer::Initialize() method. G4Initializer
|
|
// changes this state to Idle when all initialization procedures
|
|
// are successfully Done.
|
|
// Idle
|
|
// Ready to start "BeamOn". G4RunManager changes this state to
|
|
// GeomClosed when G4RunManager::BeamOn() method starts and
|
|
// G4GeometryManager::CloseGeometry() is Done. At the end of
|
|
// BeamOn() method, G4RunManager will reset the application state
|
|
// to Idle after G4GeometryManager::OpenGeometry() is Done.
|
|
// GeomClosed
|
|
// G4 is in this state between G4GeometryManager::CloseGeometry()
|
|
// and G4GeometryManager::OpenGeometry(), but no event is in
|
|
// progress. At the begining of each event (construction of a
|
|
// G4Event object and primary particle generation), G4RunManager
|
|
// changes this state to EventProc and resets to GeomClosed state
|
|
// when G4EventManager::ProcessOneEvent() is over.
|
|
// EventProc
|
|
// Processing an event.
|
|
// Quit
|
|
// G4 is in this state when the destructor of G4RunManager is invoked.
|
|
// Abort
|
|
// G4 is in this state when G4Exception is invoked.
