This is an interface class among the event, the track and the tracking category. It handles necessary message passings between the upper hierarchical object, which is the event manager (G4EventManager), and lower hierarchical objects in the tracking category. It receives one track in an event from the event manager and takes care to finish tracking it.

Geant4 kernel use only.

// Constructor/Destructor

      // TrackingManger should be dynamic persistent, therefore you
      // need to invoke new() when you call this constructor.
      // "G4SteppingManger' and "G4UserTrackingAction" will be 
      // constructed in this constructor. "This" pointer will be
      // passed to "G4UserTrackingAction". 


// Get/Set functions

   G4Track* GetTrack() const;

      // Invoking this function, the current tracking will be
      // aborted immediately. The tracking will return the 
      // G4TrackStatus in 'fUserKillTrackAndSecondaries'.
      // By this the EventManager deletes the current track and all 
      // its accoicated csecondaries.

      // This method can be invoked from the user's G4UserTrackingAction

      // class object to a G4Track object.
