0028 // Class description:
0029 //
0030 // This class extends G4UserTrackingAction 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; it owns and manages
0033 // the dependent user-actions.
0034 //
0035 // Usage:
0036 //   There is no need to explicitly use this class as long as the user actions
0037 //   are set via G4UserActionInitialization::SetUserAction(), that can be
0038 //   called several times. Explicitly this is what happens:
0039 //   In user-defined action initialization:
0040 //     G4MultiTrackingAction* action = new G4MultiTrackingAction;
0041 //     action->push_back( G4UserTrackingActionUPtr( new MyUserTrackingAction );
0042 //       [... add as many as needed ...]
0043 //     SetUserAction( action );
