2 | // Class AliRsnAnalysisManager | |
3 | // | |
4 | // This is the uppermost level of analysis objects collection. | |
5 | // It contains a list of pair managers, which all will process | |
6 | // a pool of events passed to this object, and fill their histograms. | |
7 | // | |
8 | // The utility of this object is to define a unique implementation | |
9 | // of the whole processing, which can then be included in the different | |
10 | // designs of AnalysisTask provided for SE and ME analysis. | |
11 | // | |
12 | // The base architecture is still AliRsnVManager, but in this case | |
13 | // all the objects in the list will be AliRsnPairManager's. | |
14 | // | |
