Owen O'Malley commented on ORC-256:
-----------------------------------
Ok, this is getting close. However, the numerics are more painful that I
expected. Sorry about that!
A couple of suggestions:
* We'd do better with an explicit Range class that held the start/end and make
an ArrayList of those. It would be much faster to iterate over. There isn't any
need for a synchronized container class in this context.
* You have some spurious whitespace changes at line 271 & 291.
* It probably is easier to reason about the numerics if we:
* Use the original code if there is no unmasking.
* Convert the original value to a string, use maskString, and then convert it
back.
> Add unmasked ranges option for redact mask

> It would be good to extend the Redact DataMask so that you could leave
> certain ranges of strings unmasked.
