Detailed Description

Class holding the sTGC as built conditions data and applying it. The model consists of four parameters:

• offset: shift of the strip layer in the precission coordinate
• rotation: rotation of the strip plane around the origin of the local coordinate system
• scale: correction to the pitch of the strips.
• nonPara: correction to the non parallelism of the strips

The as built parameters are applied in athenas local coordinate system. The parameters are expected in units of um and mrad

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;
}

setParameters()

StatusCode sTGCAsBuiltData::setParameters	(	const Identifier &	gasGapId,
