> Handle absent values in input (null)
> ------------------------------------
>
> Key: CSV-253
> URL: https://issues.apache.org/jira/browse/CSV-253
> Project: Commons CSV
> Issue Type: Improvement
> Components: Parser
> Reporter: Lars Bruun-Hansen
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> The parser must be able to handle absent values in input and translate that
> into {{null}} as required. I see several tickets on this matter in the
> history, but none seem to have addressed the issue, at least not for parsing.
> For this problem, I see a need to introduce a new term:
> Definition: _Absent value_ is when there are zero characters between field
> delimiters.
> Specifically the aim is to be able to parse the following:
> {noformat}
> "John",,"Doe" // 2nd element is absent
> ,"AA",123 // 1st element is absent
> "John",90, // 3rd element is absent
> "",,90 // 2nd element is absent (1st element isn't)
> {noformat}
>
> See also CSV-93 which I think never addressed the issue, probably because the
> reporter was happy with having the issue fixed for CSV output, not for
> parsing.
> A PR is coming...
