9183aa27 27// The HLT ROOT <-> binary files handling class
108615fc 28//
9183aa27 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.
35//
36// For example on how to create binary files from a AliROOT simulation,
37// see example macro exa/Binary.C.
38//
39// For reading a AliROOT file into HLT format in memory, do the following:
40//
41// AliL3FileHandler file;
42// file.SetAliInput("galice.root");
43// AliL3DigitRowData *dataPt = (AliL3DigitRowData*)file.AliDigits2Memory(nrows,eventnr);
44//
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.
47//
48// For converting the data back, and writing it to a new AliROOT file do:
49//
50// AliL3FileHandler file;
51// file.SetAliInput("galice.root");
52// file.Init(slice,patch,NumberOfRowsInPatch);
53// file.AliDigits2RootFile(dataPt,"new_galice.root");
54// file.CloseAliInput();
