39 | // A singleton. This class should be used in the analysis stage to get | |
40 | // reconstructed objects: Digits, RecPoints, TrackSegments and RecParticles, | |
41 | // instead of directly reading them from galice.root file. This container | |
42 | // ensures, that one reads Digits, made of these particular digits, RecPoints, | |
43 | // made of these particular RecPoints, TrackSegments and RecParticles. | |
44 | // This becomes non trivial if there are several identical branches, produced with | |
45 | // different set of parameters. | |
46 | // | |
47 | // An example of how to use (see also class AliPHOSAnalyser): | |
48 | // for(Int_t irecp = 0; irecp < gime->NRecParticles() ; irecp++) | |
49 | // AliPHOSRecParticle * part = gime->RecParticle(1) ; | |
50 | // ................ | |
51 | // please->GetEvent(event) ; // reads new event from galice.root | |
