0028 // Class description:
0029 //
0030 // This class extends G4UserEventAction and allows multiple user-defined
0031 // tracking actions to be used in the same job.
0032 // The class is a vector of user-defined tracking actions.
0033 // This class owns and manages the dependent user-actions.
0034 // Usage:
0035 //   There is no need to explicitly use this class as long as the
0036 //   user actions are set via G4UserActionInitialization::SetUserAction()
0037 //   that can be called several times. Explicitly, this is what is happening:
0038 //     In user-defined action initialization:
0039 //     G4MultiEventAction* action = new G4MultiEventAction;
0040 //     action->push_back( G4UserEventActionUPtr( new MyUserEventAction );
0041 //     [... add as many as needed ...]
0042 //     SetUserAction( action );
