14  * A Shipment represents the combined key/data pair for a shipment entity.
15  *
16  * <p> In this sample, Shipment is created from the stored key/data entry
17  * using TupleSerialEntityBinding. See {@link SampleViews.PartBinding} for
18  * details.
19  * </p>
20  *
21  * <p> The binding is "tricky" in that it uses this class for both the stored
22  * data entry and the combined entity object. To do this, the key field(s)
23  * are transient and are set by the binding after the data object has been
24  * deserialized. This avoids the use of a ShipmentData class completely. </p>
25  *
26  * <p> Since this class is used directly for data storage, it must be
27  * Serializable. </p>
