void HelpertRecHit2DLocalPos::getKfComponents ( KfComponentsHolder &  holder, const TrackingRecHit &  hit2dLocalPos, const GeomDet &  det  )

static

Fills in KFComponents delegating to hit2dLocalPos, plus adding APE if available hit2dLocalPos MUST BE a 2D rechit measuring local position (e.g. BaseSiTrackerRecHit2DLocalPos)
