Detailed Description

template<class hit_T, class recoHit_T>
class GFRecoHitProducer< hit_T, recoHit_T >

Template class for a hit producer module.

A GFRecoHitProducer module is used by RecoHitFactory to create RecoHits for one specific detector type.

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

In order to use the GFRecoHitProducer facility a RecoHit has to implement a constructor which takes as an argument a pointer to the cluster class. This constructor serves as the initializing constructor for the RecoHit.

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

Parameters

hit_t	template parameter specifying cluster class
recoHit_t	template parameter specifying recoHit
