20 | // AliAnalysysDataContainer - Container of data of arbitrary type deriving | |
21 | // from TObject used for analysis. A container must be connected to the | |
22 | // output data slot of a single analysis task (producer) , but also as | |
23 | // input slot for possibly several other tasks (consumers). The connected | |
24 | // slots must enforce the same data type as the container (or a derived type). | |
25 | // A container becomes the owner of the contained data once this was produced. | |
26 | // | |
27 | // Containers should be defined by the analysis module using: | |
28 | // | |
29 | // AliAnalysisModule::AddContainer(const char *name, TClass *type); | |
30 | // | |
31 | // A container should be connected to a producer: | |
32 | ||
33 | // AliAnalysisModule::ConnectOutput(AliAnalysisTask *task, | |
34 | // AliAnalysisDataContainer *cont) | |
35 | // and to its consumers: | |
36 | // | |
37 | // AliAnalysisModule::ConnectInput(AliAnalysisTask *task, Int_t islot, | |
38 | // AliAnalysisDataContainer *cont) | |
39 | // | |
40 | // The container will create an implicit connection between the producer task | |
41 | // and all consumers, which will become sub-tasks of the producer. | |
42 | // | |
