Detailed Description

Factory object to create RecoHits from digitized and clustered data.

The GFRecoHitFactory is used to automatically fill Track objects with hit data. For each detector type that is used, one GFRecoHitProducer has to be registered in the factory. The factory can the use the index information from a GFTrackCand object to load the indexed hits into the Track.

void genf::GFRecoHitFactory::addProducer	(	int	detID,
		GFAbsRecoHitProducer *	hitProd
	)

Register a producer module to the factory.

For each type of hit a separate producer is needed. The type of hit is identified by the detector ID (detID). This index corresponds to the detector ID that is stored in the GFTrackCand object

                                                                               {

void genf::GFRecoHitFactory::clear

Clear all hit producers.

}

std::vector< genf::GFAbsRecoHit * > genf::GFRecoHitFactory::createMany

(

const GFTrackCand &

cand

)

Creat a collection of RecoHits.

This is the standard way to prepare the hit collection for a Track. The resulting collection can contain hits from several detectors. The order of the hits is the same as in the GFTrackCand. It is assumed that this order is already along the track.

RecoHits have to implement a constructor which takes the cluster object from which the RecoHit is build as the only parameter. See GFAbsRecoHitProducer for details

                                                                                    {
  std::vector<genf::GFAbsRecoHit*> hitVec;
  unsigned int nHits=cand.getNHits();
  for(unsigned int i=0;i<nHits;i++) {
    unsigned int detID;
    unsigned int index;
    cand.getHit(i,detID,index);
    hitVec.push_back( createOne(detID,index) );
  }
  return hitVec;
}

genf::GFAbsRecoHit * genf::GFRecoHitFactory::createOne	(	int	detID,
		int	index
	)

Create a RecoHit.

RecoHits have to implement a Constructor which takes the cluster object from which the RecoHit is build as the only parameter. See GFAbsRecoHitProducer for details
