Member Function Documentation

getCoolChannelId()

unsigned int CaloCondUtils::getCoolChannelId ( const SYSTEM sys )

static

Returns the cool channel id associated with a given system.

Parameters

sys	The SYSTEM id

Definition at line 18 of file CaloCondUtils.cxx.

{
  return static_cast<unsigned int>(sys);
}

getDbCaloGain()

unsigned int CaloCondUtils::getDbCaloGain ( int caloGain )

static

Returns the non-negative gainId to be used with the COOL DB.

The CaloGain enumertor is negative for Tile Cells. Negative gains can not be used as an index. This function provides a non-negative index for each CaloGain

Parameters

caloGain

Input caloGain

Definition at line 86 of file CaloCondUtils.cxx.

{
 
  //=== do nothing for LAr gains
  if(caloGain>=0 && caloGain<=2) return static_cast<unsigned int>(caloGain);
  
  //=== translate tile gains
  if(caloGain==-16) return 0; //LOWLOW
  if(caloGain==-15) return 1; //LOWHIGH
  if(caloGain==-12) return 2; //HIGHLOW
  if(caloGain==-11) return 3; //HIGHHIGH
  if(caloGain== -4) return 0; //ONELOW
  if(caloGain== -3) return 3; //ONEHIGH
 
  //=== invalid gain
  {
    MsgStream log(Athena::getMessageSvc(), "CaloCondUtils::getDbCaloGain");
    log << MSG::WARNING << "invalid gain found... probably corrupted data /badly decoded ?   returns DbCaloGain 0" << endmsg; 
    return 0;
  }
  //throw CaloCond::InvalidCaloGain("CaloCondUtils::getDbCaloGain()", caloGain);
}

getFullTag()

std::string CaloCondUtils::getFullTag ( const std::string & folder, const std::string & tag )

static

Returns the full tag string, composed of camelized folder name and tag part.

The tag name conventions are outline at https://twiki.cern.ch/twiki/bin/view/Atlas/CoolTagging.

Parameters

folder	The full COOL folder path capitalized, eg. "/CALO/V01/NOISE"
tag	The tag part, eg. "XX-YYY"

Definition at line 71 of file CaloCondUtils.cxx.

{
  std::string folderTag("");
  //Copy folder name, ommiting slashes
  for (const char i : folder) {
    if (i!='/') {
      folderTag+=i;
    }
  }
  return (folderTag+"-"+tag);
}

getNCells()

unsigned int CaloCondUtils::getNCells ( const SYSTEM sys )

static

Returns the number of cells for a given system.

Parameters

sys	The SYSTEM id

Definition at line 26 of file CaloCondUtils.cxx.
