[jira] Commented: (IO-181) LineIterator should implement Iterable

["Noah Levitt (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IO-181?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12778738#action_12778738 ] 

Noah Levitt commented on IO-181:
--------------------------------

I strongly agree with the bug reporter, LineIterator should implement Iterable. Then you can write nice code like this:

for (String line: new LineIterator(reader)) {
    // ...
}

Maybe I'm missing something, but if this is the implementation of iterator(), how can it be abused?

    public Iterator<String> iterator() {
        return this;
    }

> org.apache.commons.io.LineIterator does not implement Iterable.  This makes
> it impossible to use in certain stylized ways, such as in a new-style for
> statement.  Such use is not always desirable (it might temporarily leak a
> file descriptor, until the finalizer is called), but should be possible in
> situations where it is known to be acceptable.
