void BeamHaloPropagator::setPropagationDirection ( PropagationDirection  dir )

inlineoverridevirtual

The propagation direction can now be set for every propagator. There is no more distinction between unidirectional and bidirectional at class level. The value "anyDiriction" for PropagationDirection provides the functionality of the ex-BidirectionalPropagator. The values "alongMomentum" and "oppositeToMomentum" provide the functionality of the ex-UnidirectionalPropagator.

Reimplemented from Propagator.
