Function documentation

AliITSRawStreamSDD(AliRawReader* rawReader)
 create an object to read ITS SDD raw digits
AliITSRawStreamSDD(const AliITSRawStreamSDD& rs)
 copy constructor
AliITSRawStreamSDD& operator=(const AliITSRawStreamSDD& rs)
 assignment operator
~AliITSRawStreamSDD()
UChar_t ReadBlockAttributes(AliRawReader* rawReader)
 reads block attribuited from CDH
AliITSRawStream* CreateRawStreamSDD(AliRawReader* rawReader, UChar_t attributes)
 instantiates the proper raw stream from block attributes value
AliITSRawStream* CreateRawStreamSDD(AliRawReader* rawReader)
 reads the data format from CDH and instantiates the proper raw stream
UInt_t ReadBits()
 read bits from the given channel
Int_t DecompAmbra(Int_t value) const
 AMBRA decompression (from 8 to 10 bit)
Bool_t Next()
 read the next raw digit
 returns kFALSE if there is no digit left
 returns kTRUE and fCompletedModule=kFALSE and fCompletedDDL=kFALSE when a digit is found
 returns kTRUE and fCompletedModule=kTRUE  and fCompletedDDL=kFALSE when a module is completed (=3x3FFFFFFF footer words)
 returns kTRUE and fCompletedModule=kFALSE and fCompletedDDL=kTRUE  when a DDL is completed (=jitter word)
