associate()

		const edm::EventSetup &	iSetup,
		const FreeTrajectoryState &	trackOrigin,
		const HAssociatorParameters &	parameters
	)

propagate a track across the whole detector and find associated objects. Association is done in two modes 1) an object is associated to a track only if crossed by track 2) an object is associated to a track if it is withing an eta-phi cone of some radius with respect to a track. (the cone origin is at (0,0,0))
