31 // Class Description:
32 // A G4VBiasingOperator concrete implementation example to
33 // illustrate how an operator can make use of an other operator.
34 // In the present case, the G4ChannelingOptrChangeCrossSection
35 // operator, that is made to bias processes of one particle
36 // type is instancied several times, one for each particle type
37 // to bias.
