 28 // Class description:
 29 //
 30 // Decides which intermediate points on a curved trajectory merit
 31 // being stored. Defines the compromise between accuracy of
 32 // representation of the curved trajectory and memory use.
 33 //
 34 // Derived classes should implement the filtering algorithm in the
 35 // method TakeIntermediatePoint().
 36 //
 37 // IMPORTANT: This class heap allocates vectors of auxiliary points,
 38 // which it does not delete. The vectors must find their way to a
 39 // subclass of G4VTrajectoryPoint, which must take responsibility for
 40 // deleting them.
