Class MappedStoreData

java.lang.Object
  org.jpox.store.StoreData
      org.jpox.store.mapped.MappedStoreData

public class MappedStoreData
extends StoreData

Representation of a class/field managed by the StoreManager where the datastore persists objects into a "DatastoreClass" (table).

Ownership of Tables

In JPOX, a class can have a table assigned where the class is not the "owner" of the table. This happens when the class has its fields persisted in the table of another class - so they share the table.
