28 // Class description:
29 //
30 // This class is identical to G4SmoothTrajectory 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 G4SmoothTrajectory object.
