Detailed Description

Produces reco::GenParticle from SimTracks.

The PATGenCandsFromSimTracksProducer produces GenParticles from SimTracks, so they can be used for MC matching.

Member Function Documentation

const SimTrack * PATGenCandsFromSimTracksProducer::findGeantMother	(	const SimTrack &	tk,
		const GlobalContext &	g
	)		const

private

Find the mother of a given GEANT track (or NULL if it can't be found).

Definition at line 144 of file PATGenCandsFromSimTracksProducer.cc.

edm::Ref< reco::GenParticleCollection > PATGenCandsFromSimTracksProducer::findRef	(	const SimTrack &	tk,
		GlobalContext &	g
	)		const

private

Find the GenParticle reference for a given GEANT or PYTHIA track.

if the track corresponds to a PYTHIA particle, return a ref to that particle
otherwise, if this simtrack has no mother simtrack, return a null ref
otherwise, if writeAncestors is true, make a GenParticle for it and return a ref to it
otherwise, if writeAncestors is false, return the ref to the GEANT mother of this track
