19 | // Class provides interface between classes | |
20 | // consuming/producing calibration data, | |
21 | // such as AliPHOSClusterizer and AliPHOSCalibrator | |
22 | // from one side and database (now just a root file, | |
23 | // later - AliEn etc.) | |
24 | // Use case: | |
25 | // First Manager should be configured so that is reads data | |
26 | // from a given source. e.g. from a root file: | |
27 | // AliPHOSCalibrManager * m = AliPHOSCalibrManager::GetInstance("MyCalibrationRootFile.root") ; | |
28 | // After that one can real/write data to this source: | |
29 | // AliPHOSCalibrationData mydata("Gains","v1") ; | |
30 | // ...... | |
31 | // m->Write(&mydata) ; | |
32 | // AliPHOSCalibrationData myanotherdata("Gains","v2") ; | |
33 | // m->ReadFromRoot(&myanotherdata) ; | |
