Examples of org.jpox.store.rdbms.RDBMSFetchStatement$OuterJoinDefinition

org.jpox.store.rdbms.RDBMSFetchStatement
Simple definition of a join for use internally. Used for outer joins only currently, and provides a mapping in the related table to join to (from the id of this table), together with an optional discriminator mapping in the related table with its valid values of discriminator. @version $Revision: 1.21 $
