* TransactionAware is an interface that can be implemented * to provide hooks into the Transaction interface provided * by ObJectRelationalBridge. * Only objects which have a write lock acquired on them can * participate in a transaction. * To kill a transaction, implement beforeCommit() and throw * a TransactionAbortedException. This will force the entire * transaction to rollback. * * To rebuild an object after a rollback use the afterAbort() * call. This is a good place to populate transient or other * variables. * * beforeAbort and afterCommit are there for informational * purposes. * * Here are some common ways you can expect this interface * to be called: * * Sucessful commit: * beforeCommit() * afterCommit() * * Transaction Failure (1): * beforeCommit() * beforeAbort() * afterAbort() * * Transaction Failure (2): * beforeAbort() * afterAbort() * * Commits and Aborts aren't directly provided to TransactionAware classes. * The idea is that Transactions are difficult to handle, and most of it * will be handled by ObjectSnapshot. However, you use TransactionAware * to do one of two things, kill a transaction from happening, and clean * up after a rollback. * * @version $Id: TransactionAware.java,v 1.4 2004/01/07 11:41:19 thma Exp $
