assignSD()

Gather()

StatusCode AFP_SensitiveDetectorTool::Gather ( )

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 123 of file SensitiveDetectorBase.cxx.

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

#else
  return m_SD;
#endif
}

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 30 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 150 of file SensitiveDetectorBase.cxx.

{
  // 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 the current characters of both strings match
  if (*first == *second)
    return matchStrings(first + 1, second + 1);

  // a) We consider current character of second string
  // b) We ignore current character of second string.

setSD()

void SensitiveDetectorBase::setSD ( G4VSensitiveDetector *  sd )

privateinherited

Set the current SD.

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

Definition at line 137 of file SensitiveDetectorBase.cxx.
