33
// Class Description:
34
// A G4VBiasingOperation physics-based biasing operation.
35
// If forces the physics process to not act on the track.
36
// In this implementation (meant for the ForceCollision
37
// operator) the free flight is done under zero weight for
38
// the track, and the action is meant to accumulate the weight
39
// change for making this uninteracting flight,
40
// cumulatedWeightChange.
41
// When the track reaches the current volume boundary, its
42
// weight is restored with value :
43
// initialWeight * cumulatedWeightChange
44
