19 // A singleton. This class should be used in the analysis stage to get
20 // reconstructed objects: Digits, RecPoints, TrackSegments and RecParticles,
21 // instead of directly reading them from galice.root file.
24 // The AliEMCALLoader now holds the TClonesArray and TObjArray for reading
25 // Hits, Dgits, SDigits and RecPoints. Filling is managed in the GetEvent()
28 // Creation/writing of files is managed by the relevant parts of the
29 // reconstruction software (AliEMCALDigitiser etx)
31 //*-- Author: Yves Schutz (SUBATECH) & Dmitri Peressounko (RRC KI & SUBATECH)
32 //*-- Completely redesigned by Dmitri Peressounko March 2001
34 //*-- YS June 2001 : renamed the original AliEMCALIndexToObject and make
35 //*-- systematic usage of TFolders without changing the interface
37 //*-- Marco van Leeuwen, Jan 2006: complete revision to simplify reading
38 //*-- and fit better in general ALICE scheme
