Detailed Description

template<typename T>
class HLTJetCollForElePlusJets< T >

This class is an EDProducer implementing an HLT trigger for electron and jet objects, cutting on variables relating to the jet 4-momentum representation. The producer checks for overlaps between electrons and jets and if a combination of one electron + jets cleaned against this electrons satisfy the cuts. These jets are then added to a cleaned jet collection which is put into the event.
