28 // Class description:
29 //
30 // This class extends G4TrajectoryPoint.
31 // From G4Trajectory, the following information is included:
32 // 1) Position (end of step).
33 // The extended information, only publicly accessible through AttValues,
34 // includes:
35 // 2) Auxiliary points, as in G4SmoothTrajectory.
36 // 3) Total energy deposit.
37 // 4) Remaining energy.
38 // 5) Process defining end of step.
39 // 6) Global time (from start of event) at pre- amd post-step.
40 // ...and more.
