class AliAltroRawStream: public TObject


 This class provides access to Altro digits in raw data.

 It loops over all Altro digits in the raw data given by the AliRawReader.
 The Next method goes to the next digit. If there are no digits left
 it returns kFALSE.
 Several getters provide information about the current digit.

Function documentation

AliAltroRawStream(AliRawReader* rawReader)

 create an object to read Altro raw digits

AliAltroRawStream(const AliAltroRawStream& stream)

~AliAltroRawStream()

 clean up

void Reset()

 detector id

void SelectRawData(const char* detName)

 Select the raw data for specific
 detector name

UShort_t GetNextWord()

 Read the next 10 bit word in backward direction
 The input stream access is given by fData and fPosition

First reading filling words

void ReadBunch()

 Read altro payload in
 backward direction

void ReadAmplitude()

 Read next time bin amplitude

Int_t GetPosition()

 Sets the position in the
 input stream
 Read the RCU trailer
 This includes the trailer size,
 RCU identifier and raw data payload.
 The RCU trailer format is described
 in details in the RCU manual.

UInt_t Get32bitWord(Int_t& index)

 This method returns the 32 bit word at a given
 position inside the raw data payload.
 The 'index' points to the beginning of the next word.
 The method is supposed to be endian (platform)
 independent.

Int_t ReadRCUTrailer(Int_t& index, Int_t trailerSize)

 The method decodes the RCU trailer data
 according to the RCU fw ver.2 specs

 in seconds. In case the rcu trailer
 was note read, return an invalid number (0)

 Returns the L1 phase w.r.t to the
 LHC clock

 Prints the contents of
 the RCU trailer data

Bool_t GetRCUTrailerData(UChar_t*& data) const

 Return a pointer to the RCU trailer
 data. Should be called always after

 in the GetPosition() method

void PrintDebug() const

 The method prints all the available
 debug information.
 Its is used in case of decoding errors.

 The method provides the altro chip index
 for the current hardware address.
 In case the hardware address has not been yet
 initialized, the method returns -1
