/**
|
||
* A Supplier represents the combined key/data pair for a supplier entity.
|
||
*
|
||
* <p> In this sample, Supplier 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 SupplierData class completely. </p>
|
||
*
|
||
* <p> Since this class is used directly for data storage, it must be
|
||
* Serializable. </p>
