Member Function Documentation

Int_t AliFMDAltroWriter::AddBunchTrailer (   )  [protected]

Add a bunch trailer to output. Returns: number of 10 bit words written to disk, or negative error code on failure

Int_t AliFMDAltroWriter::AddChannelTrailer (  UInt_t  hwaddr  )

Write a channel trailer to output. Parameters: hwaddr  Hardware address (channel address) Returns: Number of 10 bit words written, or negative error code on failure

Int_t AliFMDAltroWriter::AddChannelTrailer (  UShort_t  board, UShort_t  chip, UShort_t  channel )

Write a channel trailer to output. Parameters: board  The FEC board number (0-31) chip  The ALTRO chip number (0-7) channel  The ALTRO channel number (0-16) Returns: Number of 10 bit words written, or negative error code on failure

Int_t AliFMDAltroWriter::AddFillWords (   )  [protected]

Add fill words as needed to output Returns: number of 10 bit words written to disk, or negative error code on failure

Int_t AliFMDAltroWriter::AddSignal (  UShort_t  adc  )

Int_t AliFMDAltroWriter::AddToBuffer (  UShort_t  x  )  [protected]

Add a value to output buffer. Parameters: x  Value to add. Returns: number of 10 bit words written to disk, or negative error code on failure

AliFMDAltroWriter::ClassDef (  AliFMDAltroWriter  , 0  )  [protected]

Int_t AliFMDAltroWriter::Close (   )

Close the output, by writing the appropriate header. The actual stream should be called by the user. Returns: number of bytes written, or negative error code on failure

Int_t AliFMDAltroWriter::Flush (   )

Flush buffered output to file (if there is any). Returns: 0, or negative error code on failure

void AliFMDAltroWriter::SetThreshold (  UShort_t  threshold  )  [inline]

Parameters: threshold  Zero-suppresion threshold Definition at line 187 of file AliFMDAltroIO.h.
