bool GsfPropagatorAdapter::setMaxDirectionChange ( float phiMax )

inlineoverridevirtual

Set the maximal change of direction (integrated along the path) for any single propagation. If reaching of the destination surface requires change of direction that exceeds this value the Propagator returns an invalid state. For example, a track may reach a forward plane after many spirals, which may be undesirable for a track reconstructor. Setting this value to pi will force the propagation to fail. The default value is "no limit". The method returnd true if the concrete propagator respects the limit, false otherwise.

   }

void GsfPropagatorAdapter::setPropagationDirection ( PropagationDirection dir )

overridevirtual

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.
