20 | // AliAnalysisStatistics - basic class for storing statistics for the processed | |
21 | // events. The object is mergeable and can be used for general purpose. In case | |
22 | // a AliAnalysisTaskStat is used, this will set the global statistics object | |
23 | // to the analysis manager and will update it for the accepted events. | |
