69//_____________________________________________________________
70// AliHLTTPCFileHandler
71//
72// The HLT ROOT <-> binary files handling class
73//
74// This class provides the interface between AliROOT files,
75// and HLT binary files. It should be used for converting
76// TPC data stored in AliROOT format (outputfile from a simulation),
77// into the data format currently used by in the HLT framework.
78// This enables the possibility to always use the same data format,
79// whether you are using a binary file as an input, or a AliROOT file.
80//
81// For example on how to create binary files from a AliROOT simulation,
82// see example macro exa/Binary.C.
83//
84// For reading a AliROOT file into HLT format in memory, do the following:
85//
86// AliHLTTPCFileHandler file;
87// file.Init(slice,patch);
88// file.SetAliInput("galice.root");
89// AliHLTTPCDigitRowData *dataPt = (AliHLTTPCDigitRowData*)file.AliDigits2Memory(nrows,eventnr);
90//
91// All the data are then stored in memory and accessible via the pointer dataPt.
92// Accesing the data is then identical to the example 1) showed in AliHLTTPCMemHandler class.
93//
94// For converting the data back, and writing it to a new AliROOT file do:
95//
96// AliHLTTPCFileHandler file;
97// file.Init(slice,patch);
98// file.SetAliInput("galice.root");
99// file.Init(slice,patch,NumberOfRowsInPatch);
100// file.AliDigits2RootFile(dataPt,"new_galice.root");
101// file.CloseAliInput();
