19//==============================================================================
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//
9b33830a 65// The method LocalInit() may be implemented to call locally (on the client)
66// all initialization methods of the class. It is not mandatory and was created
67// in order to minimize the complexity and readability of the analysis macro.
68// DO NOT create in this method the histigrams or task output objects that will
69// go in the task output containers. Use CreateOutputObjects for that.
70//
71// The method CreateOutputObjects() has to be implemented an will contain the
c52c2132 72// objects that should be created only once per session (e.g. output
73// histograms)
74//
75// void MyAnalysisTask::CreateOutputObjects()
76//{
77 // create histograms
78// fhPt = new TH1F("fhPt","This is the Pt distribution",15,0.1,3.1);
79// fhPt->SetStats(kTRUE);
80// fhPt->GetXaxis()->SetTitle("P_{T} [GeV]");
81// fhPt->GetYaxis()->SetTitle("#frac{dN}{dP_{T}}");
82// fhPt->GetXaxis()->SetTitleColor(1);
83// fhPt->SetMarkerStyle(kFullCircle);
327eaf46 84// }
85//
86// The method Terminate() will be called by the framework once at the end of
c52c2132 87// data processing. Overload this if needed. DO NOT ASSUME that the pointers
88// to histograms defined in CreateOutputObjects() are valid, since this is
89// not true in case of PROOF. Restore the pointer values like:
90//
91//void MyAnalysisTask::Terminate(Option_t *)
92//{
93// fhPt = (TH1F*)GetOutputData(0);
94// ...
95//}
