sysStart()

virtual StatusCode AthCommonDataStore< AthCommonMsg< Gaudi::Algorithm > >::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.

updateVHKA()

void AthCommonDataStore< AthCommonMsg< Gaudi::Algorithm > >::updateVHKA ( Gaudi::Details::PropertyBase & )
