Detailed Description

template<class hit_T, class measurement_T>
class genfit::MeasurementProducer< hit_T, measurement_T >

Template class for a measurement producer module.

A MeasurementProducer module is used by MeasurementFactory to create Measurements for one specific detector type.

It is assumed that each detector has as output of its digitization / clustering some sort of hit or cluster class which stores all information that corresponds to a measured hit in that detector. The MeasurementProducer converts this information into a class that can be handled by genfit. This class is realized as a Measurement (a class inheriting from AbsMeasurement).

In order to use the MeasurementProducer facility, a Measurement has to implement a constructor which takes as an argument a pointer to the cluster class and a TrackCandHit. This constructor serves as the initializing constructor for the Measurement.

The MeasurementProducer will fetch the cluster objects from a TClonesArray and use the initializing constructor to build the corresponding Measurement.

Parameters

hit_t	template parameter specifying hit/cluster class
measurement_T	template parameter specifying Measurement
