ab2c1f0d 2// Class for handling of ESD track cuts.
3//
4// The class manages a number of track quality cuts, a
5// track-to-vertex cut and a number of kinematic cuts. Two methods
6// can be used to figure out if an ESD track survives the cuts:
7// AcceptTrack which takes a single AliESDtrack as argument and
8// returns kTRUE/kFALSE or GetAcceptedTracks which takes an AliESD
9// object and returns an TObjArray (of AliESDtracks) with the tracks
10// in the ESD that survived the cuts.
11//
5c834ad5 12//
13// TODO:
14// - add functionality to save and load cuts
5c834ad5 15// - add different ways to make track to vertex cut
16// - add histograms for kinematic cut variables?
17// - upper and lower cuts for all (non-boolean) cuts
18// - update print method
19// - is there a smarter way to manage the cuts?
aa93c798 20// - put comments to each variable
ebd60d8e 21// - implement destructor !!!
