org.apache.derby.iapi.sql.dictionary.CatalogRowFactory

org.apache.derby.impl.sql.catalog.SYSSEQUENCESRowFactory

public class SYSSEQUENCESRowFactory
extends CatalogRowFactory

Factory for creating a SYSSEQUENCES row. The contract of this table is this: if the CURRENTVALUE column is null, then the sequence is exhausted and no more values can be generated from it.
