Subject [jira] Commented: (IO-142) Retrieve Directory File List in Timestamp Order
Date Sun, 06 Jan 2008 00:42:34 GMT

    [ https://issues.apache.org/jira/browse/IO-142?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12556310#action_12556310

Niall Pemberton commented on IO-142:
------------------------------------

I have added the Comparator implementations from IO-145:

http://svn.apache.org/repos/asf/commons/proper/io/trunk/src/java/org/apache/commons/io/comparator/

So is there anything left to do for this?

>             Project: Commons IO
>          Issue Type: New Feature
>          Components: Utilities
>         Environment: Java SE 5 - Windows, Linux

> I searched your current Commons-IO issues/feature requests and did not find the following
so I'd like to propose it as a feature request.
> Given a filename filter and dir name, the method would return a List<File> of the
files that match the filter in last-modified timestamp order.
> Sun explicitly does not provide this functionality - from the Sun Java SE 5 API Javadocs,
File's listFiles() method descriptions include the following disclaimer:
>         "There is no guarantee that the name strings in the resulting array will appear
in any specific order; they are not, in particular, guaranteed to appear in alphabetical order."
> I needed the files in last-modified order so I wrote code to do it and would be glad
to share the code with the commons project if you feel it would be useful. 
> The signature is:
> - public List<File> getFileListInTimestampOrder(FilenameFilter filter, String dirName)
> I've already written, tested and used code to do this.
> There are additional flavors that might be worthwhile, too.
> - public List<File> getFileListInTimestampOrderReversed(FilenameFilter filter,
String dirName)
> - public List<File> getFileListInNameOrder(FilenameFilter filter, String dirName)
> - public List<File> getFileListInNameOrderReversed(FilenameFilter filter, String
dirName)
> BTW, I originally posted this on commons-lang but was given feedback that it might be
a better fit here.
