Matt Benson commented on IO-142:
--------------------------------
I have no objection to providing File/io-specific "building block" Comparator
implementations in [io]. Reverse lives in [collections]ReverseComparator, but
the case-insensitivity option makes me wonder whether using e.g.
TransformedComparator with InvokerTransformer, etc., from [collections]
wouldn't be the right alternative. It would be less straightforward,
obviously, but wouldn't involve as much code duplication. I suppose
case-sensitivity could be implemented as an option on a(n abstract) base class,
which defined a template method to get a String from an Object (usu. File?) to
be compared.
> Retrieve Directory File List in Timestamp Order

>
> Key: IO-142
> URL: https://issues.apache.org/jira/browse/IO-142
> Project: Commons IO
> Issue Type: New Feature
> Components: Utilities
> Environment: Java SE 5 - Windows, Linux
> Reporter: Al Scherer
>
> 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.
