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

◆ getSD()

G4VSensitiveDetector * SensitiveDetectorBase::getSD ( )

Retrieve the current SD.

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

Definition at line 118 of file SensitiveDetectorBase.cxx.

 {
 #ifdef G4MULTITHREADED
   // Get current thread-ID

◆ 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.

◆ matchStrings()

Match two strings with wildcard support.

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

◆ setSD()

Set the current SD.

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

◆ SetupEvent() [1/2]
