3 | // AliFemtoSimpleAnalysis - the most basic analysis there is. All other // | |
4 | // inherit from this one. Provides basic functionality for the analysis. // | |
5 | // To properly set up the analysis the following steps should be taken: // | |
6 | // // | |
7 | // - create particle cuts and add them via SetFirstParticleCut and // | |
8 | // SetSecondParticleCut. If one analyzes identical particle // | |
9 | // correlations, the first particle cut must be also the second // | |
10 | // particle cut. // | |
11 | // // | |
12 | // - create pair cuts and add them via SetPairCut // | |
13 | // // | |
14 | // - create one or many correlation functions and add them via // | |
15 | // AddCorrFctn method. // | |
16 | // // | |
17 | // - specify how many events are to be strored in the mixing buffer for // | |
18 | // background construction // | |
19 | // // | |
20 | // Then, when the analysis is run, for each event, the EventBegin is // | |
21 | // called before any processing is done, then the ProcessEvent is called // | |
22 | // which takes care of creating real and mixed pairs and sending them // | |
23 | // to all the registered correlation functions. At the end of each event,// | |
24 | // after all pairs are processed, EventEnd is called. After the whole // | |
25 | // analysis finishes (there is no more events to process) Finish() is // | |
26 | // called. // | |
