28 // Class description:
29 //
30 // This is a class which stores hits collections generated at one event.
31 // This class is exclusively constructed by G4SDManager when the first
32 // hits collection of an event is passed to the manager, and this class
33 // object is deleted by G4RunManager when a G4Event class object is deleted.
34 // Almost all public methods must be used by Geant4 kernel classes and
35 // the user should not invoke them. The user can use two const methods,
36 // GetHC() and GetNumberOfCollections() for accessing to the stored hits
37 // collection(s).
