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