std::pair< bool, TrajectoryStateOnSurface > GeomDetCompatibilityChecker::isCompatible ( const GeomDet *  theDet, const TrajectoryStateOnSurface &  ts, const Propagator &  prop, const MeasurementEstimator &  est  )

static

tests the geometrical compatibility of the GeomDet with the predicted state. The TrajectoryState argument is propagated to the GeomDet 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.
