30 // class description:
31 //
32 // This is the class which represents an event. A G4Event is constructed and
33 // deleted by G4RunManager (or its derived class). When a G4Event object is
34 // passed to G4EventManager, G4Event must have one or more primary verteces
35 // and primary particle(s) associated to the vertex(es) as an input of
36 // simulating an event.
37 // G4Event has trajectories, hits collections, and/or digi collections.
