Detailed Description

template<class AJet>
class hitfit::JetTranslatorBase< AJet >

Template class of function object to translate jet physics object to HitFit's Lepjets_Event_Jet object. Users need to write an implementation of a template specialization of this class for their jet physics object class. Then users combine this header file and their implementation for their analysis code. With this approach, it is possible to use HitFit for different jet physics object class in different experiments.

Parameters:

AJet	The typename of the jet physics object class to be translated into HitFit's Lepjets_Event_Jet.
