EndOfEventAction()

void G4UA::MomentumConservation::EndOfEventAction ( const G4Event *  anEvent )

overridevirtual

Todo:

Does G4PrimaryParticle really have no Get(Total/Kinetic)Energy methods?

Todo:

Do we need to add up the total energy at the start?

Todo:

Everything! Use truth strategy as for neutrinos

Definition at line 21 of file MomentumConservation.cxx.

    // Get energy of primaries

initMessaging()

void AthMessaging::initMessaging ( ) const

privateinherited

Initialize our message level and MessageSvc.

This method should only be called once.

Definition at line 39 of file AthMessaging.cxx.

{
  m_imsg = Athena::getMessageSvc();
  m_lvl = m_imsg ?
    static_cast<MSG::Level>( m_imsg.load()->outputLevel(m_nm) ) :
    MSG::INFO;
}

msg() [1/2]

MsgStream & AthMessaging::msg ( ) const

inlineinherited

The standard message stream.

Returns a reference to the default message stream May not be invoked before sysInitialize() has been invoked.

Definition at line 164 of file AthMessaging.h.

{
  MsgStream* ms = m_msg_tls.get();
  if (!ms) {
    if (!m_initialized.test_and_set()) initMessaging();
    ms = new MsgStream(m_imsg,m_nm);
    m_msg_tls.reset( ms );
  }
 
  ms->setLevel (m_lvl);
  return *ms;
}

msg() [2/2]

MsgStream & AthMessaging::msg ( const MSG::Level  lvl ) const

inlineinherited

The standard message stream.

Returns a reference to the default message stream May not be invoked before sysInitialize() has been invoked.

Definition at line 179 of file AthMessaging.h.

{ return msg() << lvl; }

msgLvl()

bool AthMessaging::msgLvl ( const MSG::Level  lvl ) const

inlineinherited

Test the output level.

Parameters

lvl	The message level to test against

Returns

boolean Indicating if messages at given level will be printed

Return values

true	Messages at level "lvl" will be printed

Definition at line 151 of file AthMessaging.h.

{
  if (!m_initialized.test_and_set()) initMessaging();
  if (m_lvl <= lvl) {
    msg() << lvl;
    return true;
  } else {
    return false;
  }
}

setLevel()

void AthMessaging::setLevel ( MSG::Level  lvl )

inherited

Change the current logging level.

Use this rather than msg().setLevel() for proper operation with MT.

Definition at line 28 of file AthMessaging.cxx.

{
  m_lvl = lvl;
}

UserSteppingAction()

void G4UA::MomentumConservation::UserSteppingAction ( const G4Step *  aStep )

overridevirtual

Todo:

Should this be GetKineticEnergy?

Definition at line 59 of file MomentumConservation.cxx.

                                                                  {
 
    if (aStep->GetPostStepPoint()->GetPhysicalVolume() != 0) {
      const double edep = aStep->GetTotalEnergyDeposit();
      _sum_edep += edep;
    } else {
      const double eesc = aStep->GetPostStepPoint()->GetTotalEnergy();
      _sum_eesc += eesc;
    }
 
  }
