20 | // AliAnalysysTask - Class representing a basic analysis task. Any | |
21 | // user-defined task should derive from it and implement the Exec() virtual | |
22 | // method. | |
23 | //============================================================================== | |
24 | // | |
25 | // A specific user analysis task have to derive from this class. The list of | |
26 | // specific input and output slots have to be defined in the derived class ctor: | |
27 | // | |
28 | // UserTask::UserTask(name, title) | |
29 | // { | |
30 | // DefineInput(0, TTree::Class()); | |
31 | // DefineInput(1, TH1::Class()); | |
32 | // ... | |
33 | // DefineOutput(0, TTree::Class()); | |
34 | // DefineOutput(1, MyObject::Class()); | |
35 | // ... | |
36 | // } | |
37 | // | |
38 | // An existing data contaner (AliAnalysisDataContainer) can be connected to the | |
39 | // input/output slots of an analysis task. Containers should not be defined and | |
40 | // connected by the derived analysis task, but from the level of AliAnalysisManager: | |
41 | // | |
42 | // AliAnalysisManager::ConnectInput(AliAnalysisTask *task, Int_t islot, | |
43 | // AliAnalysisDataContainer *cont) | |
44 | // AliAnalysisManager::ConnectOutput(AliAnalysisTask *task, Int_t islot, | |
45 | // AliAnalysisDataContainer *cont) | |
46 | // To connect a slot to a data container, the data types declared by both must | |
47 | // match. | |
327eaf46 | 48 | // |
c52c2132 | 49 | // The method ConnectInputData() has to be overloaded by the derived class in order to |
50 | // set the branch address or connect to a branch address in case the input | |
51 | // slots are connected to trees. | |
327eaf46 | 52 | // Example: |
c52c2132 | 53 | // MyAnalysisTask::ConnectInputData(Option_t *) |
327eaf46 | 54 | // { |
c52c2132 | 55 | // // One should first check if the branch address was taken by some other task |
56 | // char ** address = (char **)GetBranchAddress(0, "ESD"); | |
57 | // if (address) { | |
58 | // fESD = (AliESD*)(*address); | |
59 | // } else { | |
60 | // fESD = new AliESD(); | |
61 | // SetBranchAddress(0, "ESD", &fESD); | |
62 | // } | |
63 | // } | |
64 | // | |
65 | // The method CreateOutputObjects() has to be overloaded an will contain the | |
66 | // objects that should be created only once per session (e.g. output | |
67 | // histograms) | |
68 | // | |
69 | // void MyAnalysisTask::CreateOutputObjects() | |
70 | //{ | |
71 | // create histograms | |
72 | // fhPt = new TH1F("fhPt","This is the Pt distribution",15,0.1,3.1); | |
73 | // fhPt->SetStats(kTRUE); | |
74 | // fhPt->GetXaxis()->SetTitle("P_{T} [GeV]"); | |
75 | // fhPt->GetYaxis()->SetTitle("#frac{dN}{dP_{T}}"); | |
76 | // fhPt->GetXaxis()->SetTitleColor(1); | |
77 | // fhPt->SetMarkerStyle(kFullCircle); | |
327eaf46 | 78 | // } |
79 | // | |
80 | // The method Terminate() will be called by the framework once at the end of | |
c52c2132 | 81 | // data processing. Overload this if needed. DO NOT ASSUME that the pointers |
82 | // to histograms defined in CreateOutputObjects() are valid, since this is | |
83 | // not true in case of PROOF. Restore the pointer values like: | |
84 | // | |
85 | //void MyAnalysisTask::Terminate(Option_t *) | |
86 | //{ | |
87 | // fhPt = (TH1F*)GetOutputData(0); | |
88 | // ... | |
89 | //} | |
