18  * A Supplier represents the combined key/data pair for a supplier entity.
19  *
20  * <p> In this sample, Supplier is bound to the stored key/data entry by
21  * implementing the MarshalledTupleKeyEntity interface. </p>
22  *
23  * <p> The binding is "tricky" in that it uses this class for both the stored
24  * data entry and the combined entity object. To do this, the key field(s) are
25  * transient and are set by the binding after the data object has been
26  * deserialized. This avoids the use of a SupplierData class completely. </p>
27  *
28  * <p> Since this class is used directly for data storage, it must be
29  * Serializable. </p>
