assignSD()

Gather()

StatusCode RPCSensitiveDetectorCosmicsTool::Gather ( HitCollectionMap & )

overridevirtual

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 from SensitiveDetectorBase.

{
  return hitCollections.Record<RPCSimHitCollection>(m_outputCollectionNames[0]);
}

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()

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

staticprivateinherited

Match two strings with wildcard support.

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

Definition at line 115 of file SensitiveDetectorBase.cxx.

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

SetSensitiveDetector()

void SensitiveDetectorBase::SetSensitiveDetector ( G4LogicalVolume * logVol, G4VSensitiveDetector * aSD ) const

Method stolen from G4VUserDetectorConstruction in G4 10.2.

SetupEvent()

StatusCode RPCSensitiveDetectorCosmicsTool::SetupEvent ( HitCollectionMap & )

overridevirtual

Beginning of an athena event.

This is where collection initialization should happen. If we are using a WriteHandle, then this could be empty.
