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.
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) ;
32 // gime->Event(event) ; // reads new event from galice.root
