Subject [jira] Commented: (IO-181) LineIterator should implement Iterable
Date Wed, 18 Nov 2009 18:50:39 GMT

    [ https://issues.apache.org/jira/browse/IO-181?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12779592#action_12779592
] 

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

> may expect that each call to Iterable.iterator returns a fresh iterator that shares no
state with other iterators

Oh, right, that makes sense. Still, if something is both an Iterable and an Iterator, I think
it's intuitive (and as you point out, definitely acceptable if documented) that iterator()
would return itself.

> 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.
