class AliTOFDigitizer: public AliDigitizer

_________________________________________________________________________

This is a TTask that makes TOF-Digits out of TOF-SDigits.
The simulation of the detector is performed at sdigits level:
during digitization the unique task is the sum of all sdigits in the
same pad.
Digits are written to TreeD in branch "TOF".

Function documentation

AliTOFDigitizer()

 Default ctor - don't use it

AliTOFDigitizer(AliDigitizationInput* digInput)

ctor with RunDigitizer

AliTOFDigitizer(const AliTOFDigitizer& source)

 copy constructor

AliTOFDigitizer& operator=(const AliTOFDigitizer& source)

 ass. op.

~AliTOFDigitizer()

 Destructor

void Digitize(Option_t* option = 0)

 Perform digitization and merging.
 The algorithm is the following:
 - a hitmap is created to check if a pad is already activated;
 - an sdigits container is created to collect all sdigits from
   different files;
 - sdigits are summed using the hitmap;
 - the sdigits container is used to create the array of AliTOFdigit.

void CreateDigits()

 loop on sdigits container to fill the AliTOFdigit TClonesArray
 start digitizing all the collected sdigits

void ReadSDigit(Int_t inputFile)

 Read sdigits for current event and inputFile;
 store them into the sdigits container
 and update the hit map
 SDigits from different files are assumed to
 be created with the same simulation parameters.

void CollectSDigit(const AliTOFSDigit *const sdigit)

 Add a TOF sdigit in container
 new with placement must be used

void InitDecalibration() const

 Initialize TOF digits decalibration

void DecalibrateTOFSignal()

 Decalibrate TOF signals according to OCDB parameters

TClonesArray* SDigits() const

{return fSDigitsArray;}

Int_t PutNoise(Int_t ) const

 implemented
 due to the low
 noise expected
 level

{return 0;}
