Method Detail

commitAndResume

public void commitAndResume()

Issue a commit and then start a new transaction. This is identical to:

	pm.currentTransaction ().commit ();
	pm.currentTransaction ().begin ();
	

except that the PersistenceManager's internal atomic lock is utilized, so this method can be safely executed from multiple threads.

Since:

2.4

See Also:

Transaction.commit(), Transaction.begin()

rollbackAndResume

public void rollbackAndResume()

Issue a rollback and then start a new transaction. This is identical to:

	pm.currentTransaction ().rollback ();
	pm.currentTransaction ().begin ();
	

except that the PersistenceManager's internal atomic lock is utilized, so this method can be safely executed from multiple threads.

Since:

2.4

Transaction.rollback(), Transaction.begin()

flush

public void flush()

Flush all transactional instances to the datastore. This is particularly useful when using Kodo in conjunction with container-managed transactions, because this method allows bean code to flush any changes that the bean made to the database. This provides the bean code with an opportunity to handle any exceptions that might be raised during the flush process.

Since:

2.5.0
