Need to reset event when translateTo occur exception in RingBuffer.translateAndPublish?

[luoxn28]

If translateTo occur exception in RingBuffer.translateAndPublish，like this:

private <A> void translateAndPublish(EventTranslatorOneArg<E, A> translator, long sequence, A arg0)
{
    try
    {
        // exception occur, this event is not ok
        translator.translateTo(get(sequence), sequence, arg0);
    }
    finally
    {
        sequencer.publish(sequence);
    }
}

If occur exception, this event is incomplete, may it's old data，need reset this it？like this：

private <A> void translateAndPublish(EventTranslatorOneArg<E, A> translator, long sequence, A arg0)
{
    try
    {
        translator.translateTo(get(sequence), sequence, arg0);
    }
    catch (Exception e) {
        resetElementAt(sequence);
        throw e;
    }
    finally
    {
        sequencer.publish(sequence);
    }
}

protected final void resetElementAt(long sequence) {
    entries[BUFFER_PAD + (int) (sequence & indexMask)] = eventFactory.newInstance();
}

Personally I would do the reset in the EventHandler after the event is being processed. In the case of an exception you will need to leave some information on the event that will indicate that the event has been processed correctly, so if an exception occurs, that information will indicate that the data is not complete so the handle will discard the data, but can still reset the state of the event object.

As you say with this handling, flexibility is better for developers.
