24 | * This class translates incoming track segments structures from the TPC | |
de554e07 | 25 | * conformal mapping tracker (datatype TRAKSEGS/TPC) or tracks in global |
26 | * coordinates from the AliHLTTPCGlobalMergerComponent (TRACKS/TPC) into | |
27 | * the ESD fromat and writes it to a ROOT file. In case of TRAKSEGS, the | |
28 | * component can only process data block containing data of one slice, but | |
29 | * it can read an unlimeted number of data blocks. | |
