virtual bool TSiStripRecHit2DLocalPos::canImproveWithTrack ( ) const [inline, virtual]

Returns true if the clone( const TrajectoryStateOnSurface&) method returns an improved hit, false if it returns an identical copy. In order to avoid redundent copies one should call canImproveWithTrack() before calling clone( const TrajectoryStateOnSurface&).

TransientTrackingRecHit::RecHitPointer TSiStripRecHit2DLocalPos::clone ( const TrajectoryStateOnSurface &  ts) const [virtual]

Returns a copy of the hit with parameters and errors computed with respect to the TrajectoryStateOnSurface given as argument. For concrete hits not capable to improve their parameters and errors this method returns an exact copy, and is equivalent to clone() without arguments.

FIXME: this only uses the first cluster and ignores the others

FIXME: should report the problem somehow
