Member Function Documentation

int JetPtAssociationTool::match	(	const APVector &	aps,
		const xAOD::Jet &	jet,
		APVector &	apvs
	)			const

Return the vector of AP's that appear as constituents of the given jet. aps - input AP vector jet - Jet to be matched apvs - output vector of matched AP indices

int JetPtAssociationTool::modifyJet

(

xAOD::Jet &

jet

)

const [virtual]

Inherited method to modify a jet. Extract and record the element link and pT fraction for the jet with the highest such fraction.

Implements ISingleJetModifier.

int JetPtAssociationTool::ptfrac	(	const APVector &	aps,
		const xAOD::JetContainer &	jets,
		FloatVector &	ptsums
	)			const

Return the matched pT sum for each jet in a collection. The matching is done with match(). aps - input AP vector jet - Jet to be matched ptsums - output vector with matched pT fraction for each jet
