Interface Subtransaction

public interface Subtransaction

Subtransaction interface. Usage example:

        Subtransaction sub = session.openSubtrans();
        try {
                // do a number of operations
                ...
                // as a last step, do commit to confirm the changes
                sub.commit();
        } finally {
                // release subtrans, which rolls back the changes, unless
                // commit confirmed the changes
                sub.release();
        }
 

This pattern will make all the operations within try/finally atomic. When an error occurs, the subtransaction will be rolled back, otherwise it will be committed.
