7 // class AliRunLoader //
9 // This class aims to be the only one interface for manging data //
10 // It stores Loaders for all modules which knows the filenames //
11 // of the data files to be stored. //
12 // It aims to substitude AliRun in automatic managing of data //
13 // positioning thus there won't be necessity of loading gAlice //
14 // from file in order to get fast access to the data //
16 // Logical place to put the specific Loader to the given //
17 // detector is detector itself (i.e ITSLoader in ITS). //
18 // But, to load detector object one need to load gAlice, and //
19 // by the way all other detectors with their geometrieces and //
20 // so on. So, if one need to open TPC clusters there is no //
21 // principal nedd to read everything. //
