David Guiney created CSV-274:
--------------------------------
Summary: CSVParser.iterator() does not itterate over result set as
expected.
Key: CSV-274
URL: https://issues.apache.org/jira/browse/CSV-274
Project: Commons CSV
Issue Type: Bug
Components: Parser
Affects Versions: 1.8
Reporter: David Guiney
To return a stream of `CSVRecords` in a Spliterators, I need to call
`CSVParser.getRecords().iterator()`. I worry that the `getRecords()` will load
the records from the parser into memory, before creating the itterator which
can be a problem with large CSV files.
My code:
{code:java}
public Stream<CSVRecord> convertFileToMaps(Path path) throws IOException {
try (CSVParser parser = CSVParser.parse(path, Charset.defaultCharset(),
CSVFormat.RFC4180
.withFirstRecordAsHeader())) {
return
StreamSupport.stream(Spliterators.spliteratorUnknownSize(parser.iterator(), 0),
false);
}
}
{code}
When I collect the results of my method, it gives me
{code:java}
[]
{code}
If I replace `parser.iterator()` with `parser.getRecords().iterator()` then I
get the desired results. Is the iterator not meant to be an iterator of the
list of `CSVRecord`.
