9.8. Transaction Events

The Kodo runtime supports broadcasting transaction-related events. By registering one or more kodo.event.TransactionListeners, you can receive notifications when transactions begin, flush, rollback, commit, and more. Where appropriate, event notifications include the set of persistence-capable objects participating in the transaction.

public void addTransactionListener (Object listener);
public void removeTransactionListener (Object listener);

These methods, available on any OpenJPAEntityManager or KodoPersistenceManager, allow you to add and remove listeners.

For details on the transaction framework, see Section 11.3, “Remote Event Notification Framework” for a description of Kodo's remote event support.
