0028 // Class description:
0029 //
0030 // This class is identical to G4SmoothTrajectory class, but uses the
0031 // singleton G4Allocator so that the master thread can safely
0032 // delete the object instantiated by worker threads in sub-event
0033 // parallel mode. This class object should be instantiated as
0034 // a clone of G4SmoothTrajectory object.
