public abstract class TopiaMigrationCallbackByClass<PersistenceContext extends TopiaPersistenceContext & TopiaHibernateSupport & TopiaSqlSupport>
extends AbstractTopiaMigrationCallback<PersistenceContext>

Migration callback which use a different class for each version to migrate.

You must fill in the constructor the mapping for each version of AbstractTopiaMigrationCallback.getAvailableVersions() a matching migrator for version which extends TopiaMigrationCallbackByClass.MigrationCallBackForVersion.

Use the callback when you have a lot of version to migrate and the TopiaMigrationCallbackByMethod begins to be messy.
