public interface IsPersistable
extends HasUID, SelfValidating

Use the Persistable class as the super class of data objects to be persisted in some data store. The data store could be a client's Local Storage or the ASSISTments server database. Persistable maintains a Persistence Key that uniquely represents an instance of persistable data.

The Persistence Key is in the following format:

@<class type>/<uid>

where:

<class type> -- The superclass' name as a fully qualified name. For example: org.assisments.core.domain.Assignment. The class name can be obtained by calling .getClass().getName() on a superclass' instance. <uid> -- A unique ID.
TBS: (a) whether this is a UUID, and/or (b) whether this is a database table primary key.
