Examples of org.odmg.Transaction.abort()

org.odmg.Transaction.abort()
Abort and close the transaction. Calling abort abandons all persistent object modifications and releases the associated locks. Aborting a transaction does not restore the state of modified transient objects

        {
            Transaction tx = odmg.newTransaction();
            tx.begin();
            tx.abort();
            tx.abort();
        }
        catch(Exception e)
        {
            e.printStackTrace();
            throw e;
