4fdaad1e | 24 | * @class AliHLTTPCEsdWriterComponent |
25 | * This class translates incoming track segments structures from the TPC | |
de554e07 | 26 | * conformal mapping tracker (datatype TRAKSEGS/TPC) or tracks in global |
27 | * coordinates from the AliHLTTPCGlobalMergerComponent (TRACKS/TPC) into | |
37513ae4 | 28 | * the ESD format. |
de554e07 | 29 | * |
37513ae4 | 30 | * The \em TPCEsdWriter writes it to a ROOT file, the \em TPCEsdConverter |
31 | * to a TTree and sends the whole object to the output stream with data | |
32 | * type @ref kAliHLTDataTypeESDTree and origin TPC. | |
33 | * | |
34 | * In case of TRAKSEGS, the component can only process data block containing | |
35 | * data of one slice, but it can read an unlimeted number of data blocks. | |
