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.

Switch smoothing on or off for this track.

The "fast" parameter allows for a different method when retrieving the smoothed values with GFTools::get(biased)SmoothedData(), but is more demanding with regards to memory requirements.

this array is only to be added to in the addTrackRep method because the synchronized construction of bookkeeping objects and repAtHit array is ensured there. NEVER delete elements from this array! If this functionality will be need, it has to be done synchronized with bookkeeping!!
