Detailed Description

template<typename JetC>
class reco::JetTrackMatch< JetC >

Association between Jets from jet collection and tracks from track collection.

Every jet may have several tracks associated with it

class definition:

template <typename jetc>=""> class JetTrackMatch { public: typedef edm::Ref<JetC> JetRef; typedef edm::Ref<reco::TrackCollection> TrackRef; JetTrackMatch (); ~JetTrackMatch (); // insert orphan jet void insert (const JetRef& fJet); // assign track to jet. void insert (const JetRef& fJet, const TrackRef& fTrack); // get list of all tracks in the map std::vector <JetRef> allJets () const; // get all tracks associated with jet std::vector <TrackRef> getTracks (const JetRef& mJet) const; };
