Member Function Documentation

virtual void TArtDataFormat::FindSegment (  unsigned short *  evtdata, int *  evtsize, int *  addr, int *  nw, int *  maxsegid )  [pure virtual]

Search find segmentids in the event data. Parameters: evtdata  [in] the event data to be seached evtsize  [in] the size of the event data addr  [out] an array with the length of maxsegid where the offset of each segment is saved nw  [out] an array with the length of maxsegid where the number of words of each segment is saved maxsegid  [in] the length of the array Implemented in TArtRDF, and TArtRIDF.

virtual ArtBlockStat_t TArtDataFormat::GetNextBlock (  TArtDataSource *  source  )  [pure virtual]

Get next block from the source. The head position, the length and the type of the new block should be assigned to fBlock, fBlockLen, and fBlockType, respectively, in this method. Parameters: source  data source Returns: status of block data Implemented in TArtRDF, and TArtRIDF.

virtual ArtEventStat_t TArtDataFormat::GetNextEvent (  unsigned short *  buf, unsigned short *  runbuf, unsigned short *  rnum, int &  nw )  [pure virtual]

Get next event data. The information of the next event data will be returned to arguments. Parameters: buf  [out] the pointer to the new event runbuf  [out] the pointer to the run number in comment block rnum  [out] the pointer to the run number (used for dump data) nw  [out] the number of words in the new event Returns: status of event data Implemented in TArtRDF, and TArtRIDF.
