19// Class IceF2k
20// Conversion of Amanda F2K data into IceEvent physics event structures.
5481c137 21// This class is derived from AliJob providing a task-based processing
22// structure on an event-by-event basis.
23// The main object in the job environment is an IceEvent* pointer.
24// In case the user has provided sub-tasks, these will be executed
25// on an event-by-event basis after the IceEvent structure has been filled
26// with the F2K data and before the final structures are written out.
1c9018c6 27// Note that the data structures are only written out if an outputfile has
28// been specified via the SetOutputFile memberfunction.
29// In case no outputfile has been specified, this class provides a facility
30// to investigate/analyse F2K data using the Ralice/IcePack analysis tools.
f67e2651 31//
32// Usage example :
33// ---------------
34//
35// gSystem->Load("ralice");
36// gSystem->Load("icepack");
37// gSystem->Load("iceconvert");
38//
5481c137 39// IceF2k q("IceF2k","F2K to IcePack data structure conversion");
f67e2651 40//
41// // Limit the number of entries for testing
5481c137 42// q.SetMaxEvents(10);
f67e2651 43//
44// // Print frequency to produce a short summary print every printfreq events
5481c137 45// q.SetPrintFreq(1);
f67e2651 46//
47// // Split level for the output structures
5481c137 48// q.SetSplitLevel(2);
f67e2651 49//
50// // Buffer size for the output structures
5481c137 51// q.SetBufferSize(32000);
52//
53// // The F2K input filename
54// q.SetInputFile("run7825.f2k");
f67e2651 55//
5481c137 56// // Output file for the event structures
57// TFile* ofile=new TFile("events.root","RECREATE","F2K data in IceEvent structure");
58// q.SetOutputFile(ofile);
59//
60// ///////////////////////////////////////////////////////////////////
61// // Here the user can specify his/her sub-tasks to be executed
62// // on an event-by-event basis after the IceEvent structure
63// // has been filled and before the data is written out.
64// // Sub-tasks (i.e. a user classes derived from TTask) are entered
65// // as follows :
66// //
67// // MyXtalk task1("task1","Cross talk correction");
68// // MyClean task2("task2","Hit cleaning");
69// // q.Add(&task1);
70// // q.Add(&task2);
71// //
72// // The sub-tasks will be executed in the order as they are entered.
73// ///////////////////////////////////////////////////////////////////
74//
75// // Perform the conversion and execute subtasks (if any)
76// // on an event-by-event basis
77// q.ExecuteJob();

88//
89// TDatabasePDG* pdg=q.GetPDG();
90// if (pdg) pdg->Write();
91//
9f575717 92// // Flush the output file.
93// // The output file is not explicitly closed here
94// // to allow ineractive investigation of the data tree
95// // when this macro is run in an interactive ROOT/CINT session.
