//_________________________________________________________________________
-// A singleton that retrieves objets from an array stored in a Tree on a disk file
-// 1. AliPHOSDigit from TreeD
+// A singleton. This class should be used in the analysis stage to get
+// reconstructed objects: Digits, RecPoints, TrackSegments and RecParticles,
+// instead of directly reading them from galice.root file. This container
+// ensures, that one reads Digits, made of these particular digits, RecPoints,
+// made of these particular RecPoints, TrackSegments and RecParticles.
+// This becomes non trivial if there are several identical branches, produced with
+// different set of parameters.
+//
+// An example of how to use (see also class AliPHOSAnalyser):
+// AliPHOSIndexToObject * please = AliPHOSIndexToObject::GetInstance("galice.root","RecParticles","") ;
+// for(Int_t irecp = 0; irecp < please->GimeNRecParticles() ; irecp++)
+// AliPHOSRecParticle * part = please->GimeRecParticle(1) ;
+// ................
+// please->GetEvent(event) ; // reads new event from galice.root
