/**

* MarshalledKey is implemented by key objects and called by {@link

* SampleViews.MarshalledKeyBinding}. In this sample, MarshalledKey is
|
|||
|
|
* implemented by {@link PartKey}, {@link SupplierKey}, and {@link
|
|||
|
|
* ShipmentKey}. This interface is package-protected rather than public to

* hide the marshalling interface from other users of the data objects. Note
|
|||
|
|
* that a MarshalledKey must also have a no arguments constructor so
|
|||
|
|
* that it can be instantiated by the binding.
