Member Function Documentation

BeginOfAthenaEvent()

virtual StatusCode FastSimulationBase::BeginOfAthenaEvent ( )

inlineoverridevirtualinherited

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 ( )

privateinherited

Delete the current model.

Definition at line 99 of file FastSimulationBase.cxx.

}

EndOfAthenaEvent()

virtual StatusCode FastSimulationBase::EndOfAthenaEvent ( )

inlineoverridevirtualinherited

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 ( )

protectedinherited

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

  return fastsimmodelPair->second;
#else
  return m_FastSimModel;
#endif
}

initializeFastSim()

StatusCode FastSimulationBase::initializeFastSim ( )

overrideinherited

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.

    return StatusCode::FAILURE;
  }

}

makeFastSimModel()

G4VFastSimulationModel * NeutronFastSimTool::makeFastSimModel ( )

finaloverrideprotectedvirtual

Method to make the actual fast simulation model itself, which will be owned by the tool.

Must be implemented in all concrete base classes.

Definition at line 20 of file NeutronFastSimTool.cxx.

{
  ATH_MSG_DEBUG( "Initializing Fast Sim Model" );
 
  // Create a fresh Fast Sim Model
  return new NeutronFastSim(name(),m_trackFastSimSDName,m_etaCut,m_timeCut);
}

setFastSimModel()

void FastSimulationBase::setFastSimModel ( G4VFastSimulationModel *  fastsimmodel )

privateinherited

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();
