org.datanucleus.store.mapped.mapping.EmbeddedMapping
Mapping for an embedded PC object. The PC object can be embedded directly (1-1 relation) or be the element of a collection, or be the key or value of a map.

            DatastoreClass table = storeMgr.getDatastoreClass(cmd.getFullClassName(), clr);
            JavaTypeMapping ownerMapping = table.getMemberMapping(mmd);
            EmbeddedMapping embMapping = (EmbeddedMapping)ownerMapping;
            for (int k=0;k<embMapping.getNumberOfJavaTypeMappings();k++)
