Function documentation
Bool_t ReadNextInt()
reads next 32 bit into fDataChar1..4 (if first 16 bits read already, just completes the present word)
Int_t ReadCalibHeader()
needs to be called in the beginning of each equipment data read the extra calibration header returns the length of the header if it is present, -1 otherwise
void CheckHeaderAndTrailerCount(Int_t ddlID)
Checks that the number of header and trailers found for the ddl are as expected
void ActivateAdvancedErrorLog(Bool_t activate, AliITSRawStreamSPDErrorLog* advLogger = NULL)
Activate the advanced error logging. Logger object has to be created elsewhere and a pointer sent here.
Bool_t GetFastOrSignal(UInt_t eq, UInt_t hs, UInt_t chip)
returns if there was a fastor signal from this chip
Bool_t IsActiveChip(UInt_t eq, UInt_t hs, UInt_t chip) const
returns if the chip is active (seen in data)
Bool_t GetHalfStavePresent(UInt_t hs)
Reads the half stave present status from the block attributes
This is not really needed anymore (kept for now in case it is still used somewhere).
The same information can be reached through the "IsActiveHS" method instead.
Bool_t IsEventCounterFullConsistent() const
checks if the event counter values are consistent within the event
Short_t GetEventCounterFullHS(UInt_t eq, UInt_t hs) const
if the eq,hs is active; returns the event counter value
Short_t GetEventCounterFullChip(UInt_t eq, UInt_t hs, UInt_t chip) const
if the eq,hs,chip is active; returns the event counter value
Bool_t GetHhalfStaveScanned(UInt_t hs) const
Bool_t GetHchipPresent(UInt_t hs, UInt_t chip) const
UInt_t GetHdacHigh(UInt_t hs) const
UInt_t GetHdacLow(UInt_t hs) const
Bool_t GetHminTHchipPresent(UInt_t chip) const
UInt_t GetFOHnumDacs() const
UInt_t GetFOHdacIndex(UInt_t index) const
UInt_t GetFOHdacValue(UInt_t index) const
UInt_t GetFOHchipCount(UInt_t hs, UInt_t chip) const
Int_t GetModuleNumber(UInt_t iDDL, UInt_t iModule)
Bool_t OfflineToOnline(UInt_t module, UInt_t colM, UInt_t RowM, UInt_t& eq, UInt_t& hs, UInt_t& chip, UInt_t& col, UInt_t& row)
converts offline coordinates to online
Bool_t OnlineToOffline(UInt_t eq, UInt_t hs, UInt_t chip, UInt_t col, UInt_t row, UInt_t& module, UInt_t& colM, UInt_t& rowM)
converts online coordinates to offline
UInt_t GetOfflineChipKeyFromOnline(UInt_t eqId, UInt_t hs, UInt_t chip)
online->offline (chip key: 0-1199)
UInt_t GetOfflineColFromOnline(UInt_t eqId, UInt_t hs, UInt_t chip, UInt_t col)
online->offline (col)
UInt_t GetOfflineRowFromOnline(UInt_t eqId, UInt_t hs, UInt_t chip, UInt_t row)
online->offline (row)
Int_t GetColumn() const
the 2 methods below are equivalent to AliITSRawStream::GetCoord1 and GetCoord2 together with the AliITSRawStream::GetModuleID these are the "offline" coordinates
{return fCoord1;}UShort_t GetHalfStaveNr() const
together with the AliRawReader::GetDDLID() these are the "online" coordinates
{return fHalfStaveNr;}UInt_t GetHrouterNr() const
use the methods below to extract the information from the scan calibration header:
{return (fCalHeadWord[0] & 0x0000003f);}UInt_t GetHglobalDBversion() const
use the methods below to extract the information from the fo calibration header:
{return fCalHeadWord[16];}
