virtual void	check (lcio::LCEvent *evt)
	Called for every event - right after processEvent() has been called for all processors.

virtual void	end ()
	Called after data processing for clean up in the inverse order of the init() method so that resources allocated in the first processor also will be available for all following processors.

Detailed Description

A processor which instantiates a TrackFitterKalman and fits the tracks with it.

A collection of track candidates (lcio::Tracks) containing the TrackerHits.
Note: The LCIO::TRBIT_HITS flag has to be set when this collection is created so the hits are stored in the track.

Parameters

InputTrackCandidates	The the name of the input collection of track candidates (default: TPCTrackCandidates)
OutputTracks	The name of the collection the straight tracks be stored under (default: TPCTracks)
SetOutputTransient	If not 0 the output collection is set transient (default: 0)
TransDefocussing	The transverse defocussing in the readout structure $\sigma_{0,{\mathrm trans}}$ (in mm) (default: 1)
LongDefocussing	The longitudinal defocussing in the readout structure $\sigma_{0,{\mathrm long}}$ (in mm) (default: 1)
TransDiffusionCoef	The transverse diffusion coefficient (in mm/ $\sqrt{\mathrm mm}$ ) (default: 0)
TransDefocussing	The longitudinal diffusion coefficient (in mm/ $\sqrt{\mathrm mm}$ ) (default: 0)
