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();
  // If user did not set an explicit level, set a default
  if (m_lvl == MSG::NIL) {

      static_cast<MSG::Level>( m_imsg.load()->outputLevel(m_nm) ) :
      MSG::INFO;
  }
}

msg() [1/2]

MsgStream & asg::AsgMessaging::msg ( ) const

inherited

   }

msg() [2/2]

MsgStream & asg::AsgMessaging::msg ( const MSG::Level lvl ) const

inherited

The standard message stream.

Parameters

lvl	The message level to set the stream to

Returns

A reference to the default message stream, set to level "lvl"

Definition at line 57 of file AsgMessaging.cxx.

                                                          {

#else // not XAOD_STANDALONE
      m_msg << lvl;
      return m_msg;
#endif // not XAOD_STANDALONE
   }

msgLvl()

bool asg::AsgMessaging::msgLvl ( const MSG::Level lvl ) const

inherited

Test the output level of the object.

Parameters

lvl	The message level to test against

Returns

boolean Indicting if messages at given level will be printed

true If messages at level "lvl" will be printed

Definition at line 41 of file AsgMessaging.cxx.

                                                       {

      m_readonly = readonly;
    }

setLevel()

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

inherited

Change the current logging level.

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