ZvFitter(ZvFitter fitter)
copy constructor

ZvFitter(ZvTrackList trackList)

Method Summary

VtxFitter	copy() get a deep copy
ZvFitStatus	doFit(double[] initVtxPosition, double[] initVtxError) fit the vertex
ZvVertex	getFittedVertex() get the resulting (fitted) vertex
ZvTrackList	getNewTrackList() get the resulting (reswum) track list -- of interest, if takeNewTrackList is set to false
ZvFitStatus	getStatus() get the status of the fitter
ZvFitStatus	getStatusCopy() get the status of the fitter as a deep copy
void	setDistMin(double swimDistMin) set the minimum swim distance -- otherwise no swimming for the track necessary -- default: 0.1
void	setMaxTry(int nMaxTry) set the maximum number of tries for outer loop -- default: 3
void	setMaxTryInner(int nMaxTryInner) set the maximum number of tries for inner loop -- default: 2
void	setSwimmer(Swimmer swimmer) set the Swimmer to be used default: ZvSwimmer (with it's default settings)
void	setTrackList(ZvTrackList trackList) set track list to be fitted
void	setVtxResMax(double vtxResMax) set the maximal vertex resolution -- vertex has converged, if two subsequent fits are within this distance of each other -- default: 0.001
Swimmer	swimmer() get a handle to the swimmer used
void	takeNewTrackList(boolean choice) choose whether to record unswum (old) or swum (new) track parameters with the fitted vertex' track list
