Member Function Documentation

BeginOfAthenaEvent()

virtual StatusCode FastSimulationBase::BeginOfAthenaEvent ( )

inlineoverridevirtual

Begin of an athena event - do anything that needs to be done at the beginning of each athena event.

Reimplemented in FastCaloSimTool.

Definition at line 41 of file FastSimulationBase.h.

{ return StatusCode::SUCCESS; }

deleteFastSimModel()

void FastSimulationBase::deleteFastSimModel ( )

private

Delete the current model.

Definition at line 99 of file FastSimulationBase.cxx.

{
#ifdef G4MULTITHREADED
  for(auto& threadMapPair : m_fastsimmodelThreadMap)
    {
      auto fastSimModel = threadMapPair.second;

#else
  if(m_FastSimModel)

      delete m_FastSimModel;
      m_FastSimModel = 0;
    }
#endif
}

EndOfAthenaEvent()

virtual StatusCode FastSimulationBase::EndOfAthenaEvent ( )

inlineoverridevirtual

End of an athena event - do any tidying up required at the end of each athena event.

Reimplemented in FastCaloSimTool, and LArFastShowerTool.

Definition at line 44 of file FastSimulationBase.h.

{ return StatusCode::SUCCESS; }

getFastSimModel()

G4VFastSimulationModel * FastSimulationBase::getFastSimModel ( )

protected

Retrieve the current Fast Simulation Model.

In MT, this means the thread-local Fast Simulation Model. Otherwise, it is simply the single Fast Simulation Model.

Definition at line 73 of file FastSimulationBase.cxx.

{
#ifdef G4MULTITHREADED
  // Get current thread-ID
  const auto tid = std::this_thread::get_id();
  // Retrieve it from the FastSimModel map
  auto fastsimmodelPair = m_fastsimmodelThreadMap.find(tid);
  if(fastsimmodelPair == m_fastsimmodelThreadMap.end()) return nullptr;
  return fastsimmodelPair->second;
#else
  return m_FastSimModel;
#endif
}

initializeFastSim()

StatusCode FastSimulationBase::initializeFastSim ( )

override

Construct and setup the fast simulation model.

This method invokes the makeFastSimModel of the derived concrete tool type and assigns the configured regions. Errors are reported if regions are missing. In multi-threading jobs, this method is called once per worker thread.

Definition at line 23 of file FastSimulationBase.cxx.

    ATH_MSG_ERROR( "Failed to assign at least one volume to Fast Simulation Model " << name() );
    return StatusCode::FAILURE;
  }
 
  return StatusCode::SUCCESS;
}

setFastSimModel()

void FastSimulationBase::setFastSimModel ( G4VFastSimulationModel *  fastsimmodel )

private

Set the current model. In hive, this gets assigned as the thread-local model.

Definition at line 87 of file FastSimulationBase.cxx.

{
#ifdef G4MULTITHREADED
  // Make sure one isn't already assigned
  const auto tid = std::this_thread::get_id();

  m_fastsimmodelThreadMap.insert( std::make_pair(tid, fastsimmodel) );
#else

#endif
}
