3// class AliDataLoader //
4// //
5// Container of all data needed for full //
6// description of each data type //
7// (Hits, Kine, ...) //
8// //
9// Each data loader has a basic standard setup of BaseLoaders //
10// which can be identuified by indexes (defined by EStdBasicLoaders) //
11// Data managed by these standard base loaders has fixed naming convention //
12// e.g. - tree with hits is always named TreeH //
13// (defined in AliLoader::fgkDefaultHitsContainerName) //
14// - task DtectorName+Name defined //
15// //
16// EStdBasicLoaders idx Object Type Description //
17// kData 0 TTree or TObject main data itself (hits,digits,...) //
18// kTask 1 TTask object producing main data //
19// kQA 2 TTree quality assurance tree //
20// kQATask 3 TTask task producing QA object //
21// //
22// //
23// User can define and add more basic loaders even Run Time. //
24// Caution: in order to save information about added base loader //
25// user must rewrite Run Loader to galice.file, overwriting old setup //
26// //
