[jira] [Commented] (CSV-110) Add ability to parse single lines

["Jon Schewe (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CSV-110?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17047879#comment-17047879 ] 

Jon Schewe commented on CSV-110:
--------------------------------

Has there been anymore discussion about making the nextRecord() method public? I'd like to be able to call this method directly as well to support continually reading a file that is being appended to by another process. So I'd like to do something like:
{code:java}
for(;;) {
    String line = parser.nextRecord();
    if(null == line) {
        sleep(POLL_TIME);
    } else {
        process(line);
    }
}

{code}

> Due to the iterator-based API of CSVParser, there is currently no simple and convenient way to parse single lines of CSV-formatted data. The intention of this ticket is to add something along the lines of the following:
> {code}
> CSVLineParser lineParser = new CSVLineParser(csvFormat);
> String singleLine = "a,b,c";
> CSVRecord singleRecord lineParser.parseLine(singleLine);
> {code}
> The use case of parsing single lines comes up very often in terms of distributed batch processing scenarios (i.e. Hadoop jobs), and CSV-style formats are also regularly used in such scenarios. Currently, projects are often forced to build their own ad-hoc CSV parsing solutions, so adding the ability to parse single lines to commons-csv would be very useful to these projects, as well as anyone doing parsing based on input that isn't necessary in the form of a single stream.
