-// A singleton. This class should be used in the analysis stage to get
-// reconstructed objects: Digits, RecPoints, TrackSegments and RecParticles,
-// instead of directly reading them from galice.root file.
-//
-// MvL Feb 2006:
-// The AliEMCALLoader now holds the TClonesArray and TObjArray for reading
+// The AliEMCALLoader gets the TClonesArray and TObjArray for reading
// Hits, Dgits, SDigits and RecPoints. Filling is managed in the GetEvent()
// method.
-//
-// Creation/writing of files is managed by the relevant parts of the
-// reconstruction software (AliEMCALDigitiser etx)
+// It also provides acces methods to the calibration and simulation OCDB parameters
//
//*-- Author: Yves Schutz (SUBATECH) & Dmitri Peressounko (RRC KI & SUBATECH)
//*-- Completely redesigned by Dmitri Peressounko March 2001
//
//*-- Marco van Leeuwen, Jan 2006: complete revision to simplify reading
//*-- and fit better in general ALICE scheme
+//*-- GCB: Remove TClonesArrays and TObjArrays data members, they are created elsewhere.
+//*-- Provide access to OCDB calibration and simulation parameters.
