Detailed Description

Track object for genfit. genfit algorithms work on these objects.

Author

Christian Höppner (Technische Universität München, original author)

Sebastian Neubert (Technische Universität München, original author)

Can be used as transient (only in memory) or persistent (written to ROOT-file) object.

A GFTrack contains a collection of RecoHits plus a collection of track representations. The GFTrackCand member is a helper object to store the indices of the hits in the GFTrack.

For a GFTrack one so called "cardinal representation" can be defined. It is that track representation that is used to access the fit results. Usually one will after the fit choose the best fitting representation to be the cardinal rep.

The GFTRack takes ownership over the GFAbsRecoHit pointers it holds.

Merge two GFTracks. Only hits will be merged.

All hits from trk will be merged into this GFTrack. trk will be empty afterwards.

Kalman::continueTrack can be used to include the newly added hits in the fit.

Note that the new hits are inserted at the end of the present track!
