getImpl()

template<class CallbackT , class RecordT , class DataT >

const void* edm::eventsetup::CallbackProxy< CallbackT, RecordT, DataT >::getImpl ( const EventSetupRecordImpl &  , const DataKey &  iKey, EventSetupImpl const *    )

inlineoverridevirtual

This is the function which does the real work of getting the data if it is not already cached. The returning 'void const*' must point to an instance of the class type corresponding to the type designated in iKey. So if iKey refers to a base class interface the pointer must be a pointer to that base class interface and not a pointer to an inheriting class instance.

Implements edm::eventsetup::DataProxy.

invalidateCache()

template<class CallbackT , class RecordT , class DataT >

void edm::eventsetup::CallbackProxy< CallbackT, RecordT, DataT >::invalidateCache ( )

inlineoverridevirtual

indicates that the Proxy should invalidate any cached information as that information has 'expired' (i.e. we have moved to a new IOV)
