Examples of com.sleepycat.bdb.bind.serial.TupleSerialMarshalledBinding

com.sleepycat.bdb.bind.serial.TupleSerialMarshalledBinding
A concrete entity binding that uses the {@link MarshalledTupleKeyEntity}interface. It works by calling the methods of the {@link MarshalledTupleKeyEntity} interface, which must be implemented by the entityclass, to convert between the key/value data and entity object.
The binding is "tricky" in that it uses the entity class for both the stored data value 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 "value" class completely.
