29 //
30 // This class is identical to G4Trajectory class, but uses the
31 // singleton G4Allocator so that the master thread can safely
32 // delete the object instantiated by worker threads in sub-event
33 // parallel mode. This class object should be instantiated as
34 // a clone of G4Trajectory object.
