◆ extractConstituents() [1/2]

int JetConstituentFiller::extractConstituents	(	xAOD::Jet &	jet,
		const fastjet::PseudoJet *	ppj = `0`
	)

Build and fill constituents of jet from its PseudoJet (or from ppj) Returns the number of pseudojet constituents without user info or < 0 for error.

If the jet does not have an associated pseudojet, then the last argument is used in its place. This is for backwards compatability with code that targets release 19.1

int JetConstituentFiller::extractConstituents	(	xAOD::Jet &	jet,

		const fastjet::PseudoJet *	ppj = `0`
	)

Build and fill constituents of jet from its PseudoJet (or from ppj) Returns the number of pseudojet constituents without user info or < 0 for error.

If the jet does not have an associated pseudojet, then the last argument is used in its place. The second argments holds the list of ghost association names.
