|
//
|
|
// Used internally by weight window technique in a "parallel" geometry.
|
|
// This process is a forced post step process. It will apply
|
|
// weight window biasing on collisions or on collisions and
|
|
// boundaries according to the G4PlaceOfAction argument.
|
|
// It is not used in the case where it should apply only on boundaries.
