G4AdjointSteppingAction

public G4UserSteppingAction

//    Documentation:
//        Stepping action used in the adjoint simulation. 
//        It is responsible to stop the adjoint tracking phase when:
//            -a)The adjoint track reaches the external surface.  
//            -b)The being tracked adjoint dynamic particle get an energy higher than the maximum energy of the external source.
//            -c)The adjoint track enters the volume delimited by the adjoint source.  
//        In the case a) the info (energy,weight,...) of the adjoint dynamic particle associated to the track
//             when crossing the external source is registered and in the next event a forward primary is generated. In the other cases b) and c)
//            The next generated fwd particle is killed before being tracked and the next tracking of an adjoint particle is started directly.
