## Member Function Documentation

template<class TYPE >

DataObject* Gaudi::Utils::GetData< Gaudi::Range_< std::vector< const TYPE * > > >::getData | ( | IDataProviderSvc * | service,
|  | const std::string & | location
| ) |  | const`[inline]`

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

template<class COMMON >

return_type Gaudi::Utils::GetData< Gaudi::Range_< std::vector< const TYPE * > > >::operator() | ( | const COMMON & | common,
|  | IDataProviderSvc * | service,
|  | const std::string & | location
| ) |  | 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
