public class TupleTupleMarshalledBinding<E extends MarshalledTupleEntry & MarshalledTupleKeyEntity>
A concrete TupleTupleBinding
that delegates to the
MarshalledTupleEntry
and
MarshalledTupleKeyEntity
interfaces of the entity class.
This class calls the methods of the MarshalledTupleEntry
interface to convert between the data entry and entity object. It calls the
methods of the MarshalledTupleKeyEntity
interface to convert between
the key entry and the entity object. These two interfaces must both be
implemented by the entity class.

public TupleTupleMarshalledBinding(Class<E> cls)
The given class is used to instantiate entity objects using Class.newInstance()
, and therefore must be a public class and have a
public no-arguments constructor. It must also implement the MarshalledTupleEntry
and MarshalledTupleKeyEntity
interfaces.
