Niall Pemberton resolved IO-198.
--------------------------------
Resolution: Fixed
Thanks for the patch - I made some changes before I applied it.
The Map filtering seemed a bit odd to me - so I dropped that part of the patch.
I also changed the method signatures and added some additional ones, including
support for arrays:
{code}
public static File[] filter(IOFileFilter filter, File... files) {
public static File[] filter(IOFileFilter filter, Iterable<File> files) {
public static List<File> filterList(IOFileFilter filter, Iterable<File> files) {
public static List<File> filterList(IOFileFilter filter, File... files) {
public static Set<File> filterSet(IOFileFilter filter, File... files) {
public static Set<File> filterSet(IOFileFilter filter, Iterable<File> files) {
{code}
> Add ability in FileFilterUtils to apply file filters to collections and arrays

> Add features to FileFilterUtils that allow for filtering collections and maps
> of files that are not retrieved from directories in the standard manner. This
> feature could be useful for filtering files that are provided by the user or
> that do not all reside in the same directory.
> Example:
> List<File> files = getUserSelectedFiles();
> List<File> xmlFiles = FileFilterUtils.filterList(Arrays.<File>asList(new
> File("A.txt"), new File("B.xml")), FileFilterUtils.suffixFileFilter(".xml"));
