com.sleepycat.bind.tuple.TupleBinding<E>
public abstract class TupleBinding<E>
An abstract EntryBinding that treats a key or data entry as a
tuple; it includes predefined bindings for Java primitive types.
This class takes care of converting the entries to/from TupleInput and TupleOutput objects. Its two abstract methods must
be implemented by a concrete subclass to convert between tuples and key or
data objects.
