Example 1
protected FlushMode prepareFlushMode(Session session, boolean readOnly) throws PersistenceException {
	FlushMode flushMode = session.getFlushMode();
	if (readOnly) {
		// We should suppress flushing for a read-only transaction.
		if (!flushMode.equals(FlushMode.MANUAL)) {
			session.setFlushMode(FlushMode.MANUAL);
			return flushMode;
		}
	}
	else {
		// We need AUTO or COMMIT for a non-read-only transaction.
		if (flushMode.lessThan(FlushMode.COMMIT)) {
			session.setFlushMode(FlushMode.AUTO);
			return flushMode;
		}
	}
	// No FlushMode change needed...
	return null;
}
