Description

« Hide

My flatfiles often have many whitespaces around their lines and fields. So it would be nice to have a property to set automatic trimming the inputline and/or the resulting fieldset-fields.
I subclassed DelimitedLineTokenizer for this situation, but it might be something interesting in general.

DefaultFieldSet trims the values by default and allows you to access the non-trimmed value using readRawString(..) - doesn't this meet your needs?

Hi Robert and thanks for the quick response.
I really need the fieldnames be trimmed, too. DefaultFieldSet doesnt trim them but only the field contents. I also need the hole line getting trimmed before mapping.
I have a situation where I process csv-style files where the delimiter is a Tab. Sometimes the lines begin with a tab which will result to a field that has no name. So trimming the field-contents is not enough here.
Maybe its a bit of a exotic use-case :)
