------------------------------
Summary: Cannot get headers in column order from CSVRecord
Key: CSV-239
URL: https://issues.apache.org/jira/browse/CSV-239
Project: Commons CSV
Issue Type: Improvement
Components: Parser
Affects Versions: 1.6
Reporter: Dave Moten
I have a use case where I read many lines from an arbitrary csv file with a
given CSVFormat as List<CSVRecord>, transform that list and then want to write
the transformed list to another file.
When I specify the format as CSVFormat.DEFAULT.withFirstRecordAsHeader() the
headers from the first line are available in the CSVRecord object via the
CSVRecord.toMap object but their column positions are not (the iteration of the
returned map does not reflect column order). Consequently I cannot write a
header line in the correct order to the output csv file (which I do when the
first CSVRecord is to be written).
Another option would be to be to ensure that the CSVPrinter object writes the
header on the first call to CSVPrinter.printRecord.
My preference at minimum is that the headers with column order are available
from CSVRecord. The addition of a method `getHeaders` returning a
`List<String>` would do the job. I'm happy to submit a PR if desired.
