java.lang.Object

org.datanucleus.store.schema.table.CompleteClassTable

All Implemented Interfaces:

Table

public class CompleteClassTable
extends Object
implements Table

Representation of a table for a class where the class is stored in "complete-table" inheritance (or in JPA "TablePerClass") whereby all members (in this class and superclasses) are handled in this table. Also assumes that any persistable fields and collection/map fields are stored in this table (i.e not usable where you have foreign keys in the datastore). Currently assumes one column per basic member.
