hitfit::METTranslatorBase< AMet > Class Template Reference

Template class of function object to translate missing transverse energy physics object to HitFit's Fourvec object. Users need to write an implementation of a template specialization of this class for their missing transverse energy 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 missing transverse energy physics object class indifferent experiments. More...

Detailed Description

template<class AMet>
class hitfit::METTranslatorBase< AMet >

Template class of function object to translate missing transverse energy physics object to HitFit's Fourvec object. Users need to write an implementation of a template specialization of this class for their missing transverse energy 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 missing transverse energy physics object class indifferent experiments.

Parameters

AMet	The typename of the missing transverse energy physics object class be translated into HitFit's Fourvec.

Return the resolution corresponding to an instance of missing transverse energy object.

Parameters

met	The missing transverse energy object whose resolution is wished to be known.
useObjEmbRes	Boolean parameter to indicate if the user would like to use the resolution embedded in the object, and not the resolution read when instantiating the class.
