Examples of com.sleepycat.bind.serial.TupleSerialMarshalledBinding

com.sleepycat.bind.serial.TupleSerialMarshalledBinding
A concrete TupleSerialBinding that delegates to the MarshalledTupleKeyEntity interface of the entity class.
The {@link MarshalledTupleKeyEntity} interface must be implemented by theentity class to convert between the key/data entry and entity object.

The binding is "tricky" in that it uses the entity class for both the stored data entry and the combined entity object. To do this, the entity's key field(s) are transient and are set by the binding after the data object has been deserialized. This avoids the use of a "data" class completely.
