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 // | |
