Subject [jira] Commented: (DERBY-2485) Add OO callback scheme for transaction commit & rollback at LanguageConnectionContext layer
Date Mon, 26 Mar 2007 23:10:32 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2485?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12484257
] 

Daniel John Debrunner commented on DERBY-2485:
----------------------------------------------

I added a couple of classes (TransactionControl & TransactionListener) into a new package

org.apache.derby.iapi.transaction

These are intended as a starting point for such a callback scheme, the final api's might be
different in their approach as how to remove listeners.

These classes are not yet compiled or used by any derby code.

> Add a schemewhere objects can register to be notified before commit, rollback, savepoint/statement
rollback. This would be at the LCC layer so that it can be used by language elements and JDBC
elements. Benefits are code clarity, performance and consistent behaviour.
