// G4UserEventAction
|
|
//
|
|
// Class description:
|
|
//
|
|
// This is the base class of one of the user's optional action classes.
|
|
// The two methods BeginOfEventAction() and EndOfEventAction() are invoked
|
|
// at the beginning and the end of one event processing. These methods are
|
|
// invoked by G4EventManager.
|
|
// Be aware that BeginOfEventAction() is invoked when a G4Event object is
|
|
// sent to G4EventManager. Thus the primary vertexes/particles have already
|
|
// been made by the primary generator. In case the user wants to do something
|
|
// before generating primaries (i.e., store random number status), do it in
|
|
// the G4VUserPrimaryGeneratorAction concrete class
