#30 Add option for empty cells to be empty string vs null

[Keith Roberts]

when you call CsvListReader.read(), an empty cell gets returned as null. For my needs, an empty String would be more useful (and safer, no inadvertent NPEs). The ConvertNullTo() cell processor won't work because I don't always know how many columns I will be reading (and some have varying numbers of columns)

Can you perhaps add an option (to CsvPreferences?) to allow for deciding how an empty cell is rendered?

Hi Keith,

That would be possible, but I think it's better to use ConvertNullTo as you suggest. I've updated CsvListReader for the next release so it will be possible to execute cell processors separately from reading (feature request 31), which is really the heart of your problem.

I still think there might be some value to having the option specifically for empty cell handling, but your change certainly solves the problem.

Thanks,
Keith

Not fixing - simple solution is to use ConvertNullTo()
