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. This container | |
22 | // ensures, that one reads Digits, made of these particular digits, RecPoints, | |
23 | // made of these particular RecPoints, TrackSegments and RecParticles. | |
24 | // This becomes non trivial if there are several identical branches, produced with | |
25 | // different set of parameters. | |
26 | // | |
27 | // An example of how to use (see also class AliEMCALAnalyser): | |
28 | // for(Int_t irecp = 0; irecp < gime->NRecParticles() ; irecp++) | |
29 | // AliEMCALRecParticle * part = gime->RecParticle(1) ; | |
30 | // ................ | |
31 | // please->GetEvent(event) ; // reads new event from galice.root | |
