 org.jpox.store.AbstractDatastoreAdapter
| AbstractDatastoreAdapter | | abstract public class AbstractDatastoreAdapter implements DatastoreAdapter(Code) | | Generalised datastore representation. Each datastore is assumed to have a
"name", and a "version" (of the form major.minor.revision) and will store
"identifiers". In addition, each field will have a Mapping to the datastore
This will typically be extended to provide e.g RDBMS connection using JDBC,
or XML file connection using a DOM parser.
