00001 /* 00002 * CandViewRefTriggerBiasRemover 00003 * 00004 * Author: Evan K. Friis 00005 * 00006 * Takes a collection of "triggered" objects and returns produces a collection 00007 * that removes all elements that are biased by the trigger. In practice, this 00008 * returns an empty colleciton if the size of the input collection is 1, and the 00009 * entire collection if the input collection has at least two elements. 00010 * 00011 * In summary, for any element in the output collection, there exists at least 00012 * one *other* element in the output collection that fired the trigger. 00013 * 00014 */ 00015 00016 #include <vector> 00017 00018 #include "FWCore/Framework/interface/Frameworkfwd.h" 00019 #include "FWCore/Framework/interface/EDProducer.h" 00020 #include "FWCore/Framework/interface/Event.h" 00021 #include "FWCore/ParameterSet/interface/ParameterSet.h" 00022 00023 #include "DataFormats/Candidate/interface/Candidate.h" 00024 #include "DataFormats/Candidate/interface/CandidateFwd.h" 00025 00026 class CandViewRefTriggerBiasRemover : public edm::EDProducer { 00027 public: 00028 CandViewRefTriggerBiasRemover(const edm::ParameterSet &pset); 00029 void produce(edm::Event&, const edm::EventSetup&); 00030 private: 00031 edm::InputTag src_; 00032 }; 00033 00034 CandViewRefTriggerBiasRemover::CandViewRefTriggerBiasRemover( 00035 const edm::ParameterSet &pset) { 00036 src_ = pset.getParameter<edm::InputTag>("triggered"); 00037 produces<reco::CandidateBaseRefVector>(); 00038 } 00039 00040 void CandViewRefTriggerBiasRemover::produce(edm::Event& evt, 00041 const edm::EventSetup& es) { 00042 edm::Handle<edm::View<reco::Candidate> > cands; 00043 evt.getByLabel(src_, cands); 00044 std::auto_ptr<reco::CandidateBaseRefVector> output( 00045 new reco::CandidateBaseRefVector(cands)); 00046 // Only copy the output if there is more than one item in the input 00047 size_t nCands = cands->size(); 00048 if (nCands > 1) { 00049 //output->reserve(nCands); 00050 for (size_t iCand = 0; iCand < nCands; ++iCand) { 00051 output->push_back(cands->refVector().at(iCand)); 00052 } 00053 } 00054 evt.put(output); 00055 } 00056 00057 #include "FWCore/Framework/interface/MakerMacros.h" 00058 DEFINE_FWK_MODULE(CandViewRefTriggerBiasRemover);
