com.sleepycat.bind.tuple.TupleTupleBinding<E>
public abstract class TupleTupleBinding<E>
An abstract 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.

entryToObject in interface EntityBinding<E>key - is the source key entry.data - is the source data entry.
public void objectToKey(E object,
DatabaseEntry key)
EntityBinding
objectToKey in interface EntityBinding<E>object - is the source Object.key - is the destination entry buffer.
public void objectToData(E object,
DatabaseEntry data)
EntityBinding
objectToData in interface EntityBinding<E>object - is the source Object.data - is the destination entry buffer.

object - is the entity object.output - is the TupleOutput to which the key should be
written.
public abstract void objectToData(E object,
TupleOutput output)
object - is the entity object.output - is the TupleOutput to which the data should be
written.
