28 * @class AliHLTTPCMemHandler
29 * The HLT Binary File handler
31 * This class is the old memory I/O handler of HLT binary files.
32 * Some functionality is still used in the current code, mainly
33 * conversion of TPC digits into the format understandable by the
39 * 1) Reading a binary file:
41 * AliHLTTPCMemHandler file;
42 * file.SetBinaryInput(filename);
43 * file.Init(slice,patch);
46 * AliHLTTPCDigitRowData *data = file.CompBinary2Memory(nrows);
48 * for(int i=0; i<nrows; i++)
51 * AliHLTTPCDigitData *dataPt = (AliHLTTPCDigitData*)data->fDigitData;
52 * for(int j=0; j<data->fNDigit; j++)
54 * pad = dataPt[j].fPad;
55 * time = dataPt[j].fTime;
56 * charge = dataPt[j].fCharge;
59 * file.UpdateRowPointer(data);
62 * file.CloseBinaryInput();
63 * ________________________
65 * 2) Writing a binary file:
67 * //First of all you need to store the data in memory,
68 * //and have a pointer to it of type AliHLTTPCDigitRowData.
69 * //E.g. if you just want to write the data you read in example 1)
70 * //into a new file, you can do the following:
72 * AliHLTTPCMemHandler newfile;
73 * newfile.Init(slice,patch);
74 * newfile.SetBinaryOutput(newfilename);
75 * newfile.Memory2CompBinary((UInt_t)NumberOfRowsInPatch,(AliHLTTPCDigitRowData*)data);
76 * newfile.CloseBinaryOutput();
79 * Compressed file format:
80 * -----------------------
82 * The data is RLE encoded and currently using _10_ bit range for the ADC-values.
