◆ msg() [1/2]

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

inherited

The standard message stream.

Returns: A reference to the default message stream of this object.

◆ 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.

                                                           {

◆ msgLvl()

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

inherited

Test the output level of the object.

Parameters

◆ setLevel()

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

Change the current logging level.

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