Lars Bruun-Hansen created CSV-253:
-------------------------------------
Summary: 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
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...
