## Classes
class | Tuple
| A simple wrapper class over standard Gaudi NTuple::Tuple facility. More...
class | TupleColumn
| Helper class which allows to extend the functionality of Tuple with possibility to use your own representation of complex objects. More...
class | TupleObj
| A simple wrapper class over standard Gaudi NTuple::Tuple facility. More...
class | ItemStore
| Simple class, which represents the local storage of N-tuple items of the given type. More...
class | _TupAdapter
| Trivial adapter to avoid the GCC problem (pointer to the function is never evaluated as "const TYPE&" ) More...
## Typedefs
typedef GaudiAlg::ID | TupleID
