Gather() [1/2]

virtual StatusCode SensitiveDetectorBase::Gather ( )

inlineoverridevirtualinherited

End of an athena event.

Store the output collection in SG at this point. If we are using a WriteHandle, then this can be empty!

Reimplemented in AFP_SensitiveDetectorTool, AFP_SiDSensitiveDetectorTool, AFP_TDSensitiveDetectorTool, ALFA_SensitiveDetectorTool, CaloCellContainerSDTool, FCS_Param::FCS_StepInfoSDTool, LArG4::CalibSDTool, LArG4::SimpleSDTool, LArG4H62004ActiveSDTool, LArG4H62004DeadSDTool, LArG4H62004EMECSDTool, LArG4H62004FCALSDTool, LArG4H62004HECSDTool, LArG4H62004InactiveSDTool, LArG4H6WarmTCSDTool, MinBiasScintillatorSDTool, MuonWallSDTool, TBECBackOuterBarretteTool, TBECInnerModuleTool, TBECOuterModuleTool, ZDC_FiberSDTool, and ZDC_G4CalibSDTool.

Gather() [2/2]

virtual StatusCode TileGeoG4SDTool::Gather ( HitCollectionMap & )

finaloverridevirtual

End of an athena event.

Reimplemented from SensitiveDetectorBase.

getSD()

G4VSensitiveDetector * SensitiveDetectorBase::getSD ( )

protectedinherited

Retrieve the current SD.

In AthenaMT, this means the thread-local SD. Otherwise, it is simply the single SD.

Definition at line 120 of file SensitiveDetectorBase.cxx.

{
#ifdef G4MULTITHREADED
  // Get current thread-ID
  const auto tid = std::this_thread::get_id();
  // Retrieve it from the SD map

  return sdPair->second;
#else
  return m_SD;
#endif
}

initialize()

virtual StatusCode TileGeoG4SDTool::initialize ( )

finaloverridevirtual

Default destructor is just fine.

initializeSD()

StatusCode SensitiveDetectorBase::initializeSD ( )

overrideinherited

Setup an SD in the current thread.

Separate from the AthAlgTool initialize() method because it needs to be called once per worker thread in AthenaMT. Don't confuse this with the G4 SD method Initialize which is called at the beginning of every G4 event.

Definition at line 25 of file SensitiveDetectorBase.cxx.

makeSD()

Make me an SD!

matchStrings()

bool SensitiveDetectorBase::matchStrings ( const char * first, const char * second )

Match two strings with wildcard support.

Compares two strings character by character with optional * wildcard in the first argument

  // If we reach at the end of both strings, we are done
  if (*first == '\0' && *second == '\0')

  if (*first == '*' && *(first + 1) != '\0' && *second == '\0')
    return false;

  if (*first == *second)

setSD()

void SensitiveDetectorBase::setSD ( G4VSensitiveDetector * sd )

Set the current SD.

In hive, this gets assigned as the thread-local SD.
