Subject [jira] [Commented] (CSV-155) Get remaining unformatted text
Date Thu, 13 Aug 2015 00:07:46 GMT


Gary Gregory commented on CSV-155:

Seems like you need to spend some time hacking around to see how to do this ;-)

> Get remaining unformatted text
> ------------------------------
>                 Key: CSV-155
>                 URL:
>             Project: Commons CSV
>          Issue Type: New Feature
>          Components: Parser
>    Affects Versions: 1.1
>            Reporter: Jason Steenstra-Pickens
> I have the requirement where I need to parse the headers of a CSV string so that I can
validate them and then remove those headers.
> The problem is that the CSVParser creates an internal ExtendedBufferedReader from the
given reader (which in my case is a StringReader). Reading the first record will read and
buffer additional records so if I then try and read directly from the StringReader it does
not return anything.
> To solve this I need to be able to do one of the following:
> # pass in my own ExtendedBufferedReader (so would need to be made public)
> # have a new getter method to be able to retrieve the internal ExtendedBufferedReader
(or as a BufferedReader, either will do)
> # have a new method on the CSVParser to be able to retrieve the remaining raw records.
> The current workaround is to read all the records and then write all the records except
the first back out to a StringWriter but this is a lot of unnecessary work and code. This
doesn't really work since it reader and writing it back out has a very high chance of modifying
the quotes, escapes, whitespace etc.
