Detailed Description

Collection of TrackPoint objects, AbsTrackRep objects and FitStatus objects.

Holds a number of AbsTrackRep objects, which correspond to the different particle hypotheses or track models which should be fitted. A 6D seed stateSeed_ (x,y,z,p_x,p_y,p_z) and 6x6 covSeed_ should be provided as start values for fitting. When fitting the Track with a AbsFitter, a FitStatus object will be created, containing information about the fit. The fitted states will be stored in AbsFitterInfo objects in every TrackPoints.

The fit will be performed for every AbsTrackRep, so after the fit there will be one AbsFitterInfo for each AbsTrackRep in every TrackPoint, as well as one FitStatus for every AbsTrackRep.

genfit::Track::Track	(	const TrackCand &	trackCand,
		const MeasurementFactory< genfit::AbsMeasurement > &	factory,
		AbsTrackRep *	rep = `nullptr`
	)

@ brief Construct Track from TrackCand, using a MeasurementFactory

The MeasurementFactory will be used to create AbsMeasuremen objects. TrackPoints will be created. If two or more consecutive PlanarMeasurement objects with the same detector- and planeId are created by the factory, they will be put into the same TrackPoint.

Optionally, a AbsTrackRep can be provided.

The stateSeed_ of the Track will be filled with the seed of the TrackCand. A guess for covSeed_ will be made using the largest entry of the cov of the first measurement and the number of measurements (For the covSeed_, it is just important that it will be big enough not to bias the fit too much, but not too big in order to avoid numerical problems).

TrackCand * genfit::Track::constructTrackCand ( ) const

Construct a new TrackCand containing the hit IDs of the measurements.

The idea is hat you can get a TrackCand for storing the hit IDs after a track has been fitted. His could have been reordered, added or removed, so that the original TackCand no longer represents the Track correctly. You might want to call determineCardinalRep() and/or udpateSeed() before.
