25// A singleton. This class should be used in the analysis stage to get
26// reconstructed objects: Digits, RecPoints, TrackSegments and RecParticles,
27// instead of directly reading them from galice.root file. This container
28// ensures, that one reads Digits, made of these particular digits, RecPoints,
29// made of these particular RecPoints, TrackSegments and RecParticles.
30// This becomes non trivial if there are several identical branches, produced with
31// different set of parameters.
32//
33// An example of how to use (see also class AliPHOSAnalyser):
34// AliPHOSGetter * gime = AliPHOSGetter::GetInstance("galice.root","test") ;
35// for(Int_t irecp = 0; irecp < gime->NRecParticles() ; irecp++)
36// AliPHOSRecParticle * part = gime->RecParticle(1) ;
37// ................
38// please->GetEvent(event) ; // reads new event from galice.root
