5 // Class AliRsnListOutput
7 // This class defines a base classe to implement a Output
8 // which uses the internal RSN package event format (AliRsnEvent).
9 // It contains some default flags which turn out to be useful:
10 // - a flag to select only the "true" pairs (tracks from same resonance)
11 // - a flag to know if the computation is done over two events (mixing)
13 // Any kind of analysis object should be implemented as inheriting from this
14 // because the AliRsnAnalyzer which executes the analysis will accept a collection
15 // of such objects, in order to have a unique format of processing method
17 // The user who implements a kind of computation type should inherit from
18 // this class and override the virtual Outputs defined in it, which
19 // initialize the final output histogram and define how to process data.
