A specialization of the DetLayer interface for barrel layers. Barrel layers are cylinders with their axes parallel to the global Z axis. The methods that have a common implementation for all BarrelDetLayers are implemented in this class, but some methods are left abstract.

tests the geometrical compatibility of the Det with the predicted state. The FreeTrajectoryState argument is propagated to the Det surface using the Propagator argument. The resulting TrajectoryStateOnSurface is tested for compatibility with the surface bounds. If compatible, a std::pair< true, propagatedState> is returned. If the propagation fails, or if the state is not compatible, a std::pair< false, propagatedState> is returned.
Implements GeometricSearchDet.
