[jira] [Updated] (CSV-297) setHeader() does not consider the separator while parse header row
[ https://issues.apache.org/jira/browse/CSV-297?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Marco Cuccato updated CSV-297:
------------------------------
Description:
If you try to parse a file like this:
{code:java}
name$value
a$1
b$0
c$3{code}
with a CSVFormat defined like this:
{code:java}
CSVFormat.DEFAULT.builder()
.setRecordSeparator("$")
.setHeader()
.build();
{code}
and then try to retrieve a field by name with:
{code:java}
record.get("name"){code}
i get the following error:
{code:java}
java.lang.IllegalArgumentException: Mapping for name not found, expected one of [name$value]
at org.apache.commons.csv.CSVRecord.get(CSVRecord.java:121)
{code}
Looks like the parser does not consider the separator when auto detects headers.
If I modify the source file using comma as separator and
{code:java}
format.setRecordSeparator(","){code}
it works.
