finalReset()

{};

isSet()

virtual bool IResetable::isSet ( ) const

pure virtual

Implemented in SG::VarHandleBase, and DataHandleBase.

key()

virtual const std::string& IResetable::key ( ) const

pure virtual

Implemented in SG::VarHandleBase, and DataHandleBase.

reset()

virtual void IResetable::reset ( bool  hard )

pure virtual

Clear cached data from this object.

If HARD is true, then also clear any data that depends on the identity of the current event store. HARD will be set if the handle could potentially be looking at a different store the next time it is used. (This happens in Hive.)

For example, a VarHandle caches both a pointer to the referenced object and a pointer to the DataProxy used to reference it. If HARD is false, then only the object pointer need be cleared; but if it is true, then the DataProxy pointer should be cleared as well (and the object deregistered from the store).

Implemented in DataHandle< DATA >, DataHandle< ILArPedestal >, DataHandle< CondAttrListCollection >, DataHandle< ILArShape >, DataHandle< CondMultChanCollection >, DataHandle< ILArAutoCorr >, DataHandle< CaloRec::CaloCellFactor >, DataHandle< AthenaAttributeList >, DataHandle< GenericDbTable >, DataHandle< StrawDxContainer >, SG::VarHandleBase, and SG::UpdateHandle< T >.
