virtualinherited

Add a variable to the tuple.

Parameters

Parameters

p	The object to release.

Call this when you are done with the object returned by nextUntyped(). The default implementation is a no-op, but if the association dynamically allocated the object which it returned, this gives it a chance to free it.

reset()

StatusCode D3PD::ElectronJetDRAssociator::reset ( const xAOD::Electron &  eg )

overridevirtual

Start the iteration for a new association.

Parameters

p	The object from which to associate.

Implements D3PD::MultiAssociationTool< xAOD::Electron, xAOD::Jet >.

resetUntyped()

virtual StatusCode D3PD::MultiAssociationTool< xAOD::Electron , xAOD::Jet >::resetUntyped ( const void *  p )

virtualinherited

Start the iteration for a new association.

Parameters

p	The object from which to associate.
