3 | // Basic class for Performance/Calibration TRD tasks | |
4 | // | |
5 | // It performs generic tasks like : | |
6 | // - data file manegment | |
7 | // - reference container management | |
8 | // - debug container management | |
9 | // - interaction with AliAnalysisManager | |
10 | // - Plot functor loop | |
