Examples of com.sleepycat.bdb.bind.tuple.TupleTupleMarshalledBinding

com.sleepycat.bdb.bind.tuple.TupleTupleMarshalledBinding
A concrete entity binding that uses the {@link MarshalledTupleData} and the{@link MarshalledTupleKeyEntity} interfaces. It calls the methods of the{@link MarshalledTupleData} interface to convert between the value data andentity object. It calls the methods of the {@link MarshalledTupleKeyEntity}interface to convert between the key data and the entity object. These two interfaces must both be implemented by the entity class @author Mark Hayes
