/* $Id$ */

// This class runs the test preprocessor
// It uses AliTestShuttle to simulate a full Shuttle process

// The input data is created in the functions
//   CreateDCSAliasMap() creates input that would in the same way come from DCS
//   ReadDCSAliasMap() reads from a file
//   CreateInputFilesMap() creates a list of local files, that can be accessed by the shuttle

  // TODO(1)
  //
  // The shuttle can read DCS data, if the preprocessor should be tested to process DCS data,
  // some fake data has to be created.
  //
  // The "fake" input data can be taken using either (a) or (b):
  // (a) data from a file: Use ReadDCSAliasMap()
  //     the format of the file is explained in ReadDCSAliasMap()
  //     To use it uncomment the following line:
  //
  //TMap* dcsAliasMap = ReadDCSAliasMap();
  //
  // (b) generated in this macro: Use CreateDCSAliasMap() and its documentation
  //     To use it uncomment the following line:
  //
  TMap* dcsAliasMap = CreateDCSAliasMap();
  //WriteDCSAliasMap();

  // now give the alias map to the shuttle
  shuttle->SetDCSInput(dcsAliasMap);

  // TODO(2)
  //
  // The shuttle can also process files that originate from DCS, DAQ and HLT.
  // To test it, we provide some local files and locations where these would be found when
  // the online machinery would be there.
  // In real life this functions would be produces by the sub-detectors
  // calibration programs in DCS, DAQ or HLT. These files can then be retrieved using the Shuttle.
  //
  // Files are added with the function AliTestShuttle::AddInputFile. The syntax is:
  // AddInputFile(<system>, <detector>, <id>, <source>, <local-file>)
  // In this example we add a file originating from the GDC with the id PEDESTALS
  // Three files originating from different LDCs but with the same id are also added
  // Note that the test preprocessor name is TPC. The name of the detector's preprocessor must follow
  // the "online" naming convention ALICE-INT-2003-039.
