public abstract class TupleTupleBinding<E> extends TupleBase<E> implements EntityBinding<E>
EntityBinding that treats an entity's key entry and
data entry as tuples.
This class takes care of converting the entries to/from TupleInput and TupleOutput objects. Its three abstract methods
must be implemented by a concrete subclass to convert between tuples and
entity objects.
