Declare a new Gaudi property.

Parameters

◆ outputHandles()

virtual std::vector<Gaudi::DataHandle*> AthCommonDataStore< AthCommonMsg< AlgTool > >::outputHandles ( ) const

Return this algorithm's output handles.

We override this to include handle instances from key arrays if they have not yet been declared. See comments on updateVHKA.

◆ queryInterface()

◆ sysInitialize()

virtual StatusCode AthCommonDataStore< AthCommonMsg< AlgTool > >::sysInitialize ( )

overridevirtualinherited

Perform system initialization for an algorithm.

We override this to declare all the elements of handle key arrays at the end of initialization. See comments on updateVHKA.

Reimplemented in DerivationFramework::CfAthAlgTool, AthCheckedComponent< AthAlgTool >, AthCheckedComponent<::AthAlgTool >, and asg::AsgMetadataTool.

◆ sysStart()

virtual StatusCode AthCommonDataStore< AthCommonMsg< AlgTool > >::sysStart ( )

overridevirtualinherited

Handle START transition.

We override this in order to make sure that conditions handle keys can cache a pointer to the conditions container.

◆ toTruthParticle()

const xAOD::TruthParticle * D3PD::PhotonTruthTool::toTruthParticle ( const xAOD::Photon & g ) const

Go from a photon to a matching TruthParticle.

Parameters

g	The input photon.
cache	Truth classifier association cache.

Returns: The matching TruthParticle, or null.

Parameters

g	The input photon.

Returns: The matching TruthParticle, or null.
