Subject [jira] [Commented] (CSV-85) Allow comments to be returned in CSVRecord
Date Mon, 26 Mar 2012 22:06:27 GMT

    [ https://issues.apache.org/jira/browse/CSV-85?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13238900#comment-13238900

Emmanuel Bourg commented on CSV-85:
-----------------------------------

Assuming that inline comments are dropped, I would define a record comment as the concatenation
of the comment lines preceding the current record in the file (up to the previous record).

1. The simple case, a one line comment:

{code}
# Comment
a,b,c,e,f
{code}

Expected record comment: "Comment" (the comment char and the leading space are removed)

2. A comment on multiple lines

{code:none}
# Very Long
# Comment
a,b,c,e,f
{code}

Expected record comment: "Very Long\nComment"

3. A comment on multiple lines, with blank lines interleaved

{code:none}
# Very Long

# Comment
a,b,c,e,f
{code}

Here the result depends on the empty line handling. If empty lines are ignored this is equivalent
to the previous case. If empty lines are not ignored, this will produce two records, the first
one with the comment "Very Long" and the second one with "Comment".

> It might be useful to provide a comment field in the CSVRecord class.
> This would be null if no comment is present for that record.
> A line consisting of only a comment would have a size() of 0.
