template<class TYPE >

DataObject* Gaudi::Utils::GetData< Gaudi::Range_< std::vector< const TYPE * > > >::getData	(	IDataProviderSvc *	service,

get the data form transient store

Parameters:

service	pointer to data provider service
location	the location

Returns:

the object for TES

Try to be efficient

		IDataProviderSvc *	service,

	)		const [inline]

the only one essential method

Parameters:

common	the actual "worker"
service	pointer to Data Provider Service
location	location of objects in TES

Returns:

the data

try to be efficient: 1. load object only once:

2. try to get the selection

3. try to get the container
