Detailed Description

Tool for constructing H62004 SDs for HEC.

Based on the previous LArG4H62004HECSDTool implementation.

This implementation uses the LAr SD wrapper design for managing multiple SDs when running multi-threaded. See ATLASSIM-2606 for discussions.

Gather()

StatusCode LArG4::SimpleSDTool::Gather ( )

finaloverridevirtualinherited

Calls down to all the SDs to pack their hits into one collection.

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
  auto sdPair = m_sdThreadMap.find(tid);
  if(sdPair == m_sdThreadMap.end()) return nullptr;
  return sdPair->second;
#else
  return m_SD;
#endif
}

initialize()

StatusCode LArG4::SimpleSDTool::initialize ( )

finaloverrideinherited

Initialize the tool.

initializeCalculators()

StatusCode LArG4::H62004HECSDTool::initializeCalculators ( )

finaloverrideprivatevirtual

Initialize Calculator Services.

Reimplemented from LArG4::SimpleSDTool.

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.

protectedinherited

Override helper method to create one SD.

makeSD()

G4VSensitiveDetector* LArG4::H62004HECSDTool::makeSD ( ) const

finaloverrideprivate

Create the SD wrapper for current worker thread.

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')
    return true;

  // advance to the next character

  // b) We ignore current character of second string.
  if (*first == '*')
    return matchStrings(first + 1, second) || matchStrings(first, second + 1);
  return false;
}

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.

{
#ifdef G4MULTITHREADED
  const auto tid = std::this_thread::get_id();

}

SetSensitiveDetector()

Method stolen from G4VUserDetectorConstruction in G4 10.2.

SetupEvent()

virtual StatusCode SensitiveDetectorBase::SetupEvent ( )

inlineoverridevirtualinherited

Beginning of an athena event.

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