◆ addBranch() [2/2]

StatusCode CP::RNtupleFieldHelpers::ElementProcessor::addBranch	(	TTree &	,

overridevirtual

Add one branch to the output tree.

This function is used during the setup of the output tree to create one branch in it, from one specific auxiliary variable. The type of the variable is figured out at runtime using the auxiliary store infrastructure.

Parameters

tree	The tree to create the branch in
auxName	Name of the auxiliary variable to create the branch from
branchName	The name of the branch to create in the tree

Returns: The usual StatusCode values

}

◆ msg() [1/2]

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

◆ msg() [2/2]

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

inherited

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

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.

◆ retrieveProcess()

StatusCode CP::RNtupleFieldHelpers::ElementProcessor::retrieveProcess ( StoreType & evtStore )

retrieve and process the object

This function is called during the event processing to first retrieve the object from the event store, and then to extract all configured variables from the xAOD object into the output variables set up via addBranch.

Implements CP::TreeBranchHelpers::IObjectProcessor.

Reimplemented in CP::RNtupleFieldHelpers::ElementProcessorMet.

        }
        return StatusCode::SUCCESS;
    }

◆ setLevel()

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

inherited

Change the current logging level.

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