Subject [jira] [Commented] (CSV-82) CSVRecord inconsistent behaviour when header mapping is not found
Date Mon, 26 Mar 2012 13:16:28 GMT


Sebb commented on CSV-82:

bq. In case 2 a null value is returned, because some column may be optional.

I don't understand this concept of optional columns.
Surely any CSV header line needs to provide names for all the columns?
Otherwise, what's the point of the header line?

> The CSVRecord#get(String) method has inconsistent behaviour.
> If no header mapping was provided, then it throws IllegalStateException.
> If the header name is not found, null is returned.
> Apart from being inconsistent, it might be useful in the future to be able to return
null as a column value (as distinct from the empty string).
> It should throw IllegalArgumentException for a missing header name, instead of returning
