Member Function Documentation

template<class RecordT , class DataT >

virtual const void* edm::eventsetup::DataProxyTemplate< RecordT, DataT >::getImpl	(	const EventSetupRecord &	,
		const DataKey &	iKey
	)		[inline, virtual]

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.
