19 | // A singleton. This class should be used in the analysis stage to get | |
20 | // reconstructed objects: Digits, RecPoints, TrackSegments and RecParticles, | |

5dee926e | 23 | // MvL Feb 2006: |
24 | // The AliEMCALLoader now holds the TClonesArray and TObjArray for reading | |
25 | // Hits, Dgits, SDigits and RecPoints. Filling is managed in the GetEvent() | |
26 | // method. | |
27 | // | |
28 | // Creation/writing of files is managed by the relevant parts of the | |
29 | // reconstruction software (AliEMCALDigitiser etx) | |
