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 AliPHOSAnalyser): |
28 | // AliPHOSGetter * gime = AliPHOSGetter::GetInstance("galice.root","test") ; |
29 | // for(Int_t irecp = 0; irecp < gime->NRecParticles() ; irecp++) |
30 | // AliPHOSRecParticle * part = gime->RecParticle(1) ; |
31 | // ................ |
