+/**
+ * A Shipment represents the combined key/data pair for a shipment entity.
+ *
+ * <p> In this sample, Shipment is bound to the stored key/data entry by
+ * implementing the MarshalledTupleKeyEntity interface. </p>
+ *
+ * <p> The binding is "tricky" in that it uses this class for both the stored
+ * data entry and the combined entity object.  To do this, the key field(s)
+ * are transient and are set by the binding after the data object has been
+ * deserialized. This avoids the use of a ShipmentData class completely. </p>
+ *
+ * <p> Since this class is used directly for data storage, it must be
+ * Serializable. </p>
