27 // The HLT ROOT <-> binary files handling class
29 // This class provides the interface between AliROOT files,
30 // and HLT binary files. It should be used for converting
31 // TPC data stored in AliROOT format (outputfile from a simulation),
32 // into the data format currently used by in the HLT framework.
33 // This enables the possibility to always use the same data format,
34 // whether you are using a binary file as an input, or a AliROOT file.
36 // For example on how to create binary files from a AliROOT simulation,
37 // see example macro exa/Binary.C.
39 // For reading a AliROOT file into HLT format in memory, do the following:
41 // AliL3FileHandler file;
42 // file.SetAliInput("galice.root");
43 // AliL3DigitRowData *dataPt = (AliL3DigitRowData*)file.AliDigits2Memory(nrows,eventnr);
45 // All the data are then stored in memory and accessible via the pointer dataPt.
46 // Accesing the data is then identical to the example 1) showed in AliL3MemHandler class.
48 // For converting the data back, and writing it to a new AliROOT file do:
50 // AliL3FileHandler file;
51 // file.SetAliInput("galice.root");
52 // file.Init(slice,patch,NumberOfRowsInPatch);
53 // file.AliDigits2RootFile(dataPt,"new_galice.root");
54 // file.CloseAliInput();
