initMessaging()

void AthMessaging::initMessaging ( ) const

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 167 of file AthMessaging.h.

{
  MsgStream* ms = m_msg_tls.get();

Definition at line 182 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 user did not set explicit message level we have to initialize
  // the messaging and retrieve the default via the MessageSvc.

virtual long EventInfoByteStreamxAODCnv::repSvcType ( ) const

inlineoverridevirtual

Storage type and class ID.

Definition at line 39 of file EventInfoByteStreamxAODCnv.h.

{ return i_repSvcType(); }

setLevel()

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

inherited

Change the current logging level.

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