Detailed Description

template<class measurement_T>
class genfit::MeasurementFactory< measurement_T >

Factory object to create AbsMeasurement objects from digitized and clustered data.

The MeasurementFactory is used to automatically fill Track objects with hit data. For each detector type used an AbsMeasurementProducer has to be registered in the factory. The factory can then use the index information from a TrackCand object to load the indexed hits into the Track.

◆ addProducer()

void addProducer	(	int	detID,
		AbsMeasurementProducer< measurement_T > *	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 TrackCand.

     hitProdMap_[detID] = hitProd;

     Exception exc("MeasurementFactory: detID already in use",__LINE__,__FILE__);
     exc.setFatal();
     std::vector<double> numbers;
     numbers.push_back(detID);
     exc.setNumbers("detID",numbers);
     throw exc;
   }
 }

◆ createMany()

std::vector< measurement_T * > createMany ( const TrackCand & cand ) const

Create a collection of Measurements.

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 TrackCand. It is assumed that this order is already along the Track.

Measurements have to implement a constructor which takes the cluster object from which the Measurement is built as the only parameter.

◆ createOne()

measurement_T * createOne	(	int	detID,
		int	index,
		const TrackCandHit *	hit
	)		const

Create a Measurement.

Measurements have to implement a Constructor which takes the cluster object from which the Measurement is built as the only parameter.
