Description

Apache Commons IO has a similar file filter concept as VFS and provides ~20 filter implementations. VFS misses such implementations.

Therefore I ported the IO filters, created & updated unit tests and now I want to contribute that code to VFS.

The code is currently available on GitHub:
https://github.com/fuinorg/commons-vfs2-filters

---

New filters are:

• org.apache.commons.vfs2.filter.AgeFileFilter
• org.apache.commons.vfs2.filter.AndFileFilter
• org.apache.commons.vfs2.filter.CanReadFileFilter
• org.apache.commons.vfs2.filter.CanWriteFileFilter
• org.apache.commons.vfs2.filter.ConditionalFileFilter
• org.apache.commons.vfs2.filter.DirectoryFileFilter
• org.apache.commons.vfs2.filter.EmptyFileFilter
• org.apache.commons.vfs2.filter.FalseFileFilter
• org.apache.commons.vfs2.filter.FileFileFilter
• org.apache.commons.vfs2.filter.HiddenFileFilter
• org.apache.commons.vfs2.filter.NameFileFilter
• org.apache.commons.vfs2.filter.NotFileFilter
• org.apache.commons.vfs2.filter.OrFileFilter
• org.apache.commons.vfs2.filter.PrefixFileFilter
• org.apache.commons.vfs2.filter.RegexFileFilter
• org.apache.commons.vfs2.filter.SizeFileFilter
• org.apache.commons.vfs2.filter.SizeRangeFileFilter
• org.apache.commons.vfs2.filter.SuffixFileFilter
• org.apache.commons.vfs2.filter.TrueFileFilter
• org.apache.commons.vfs2.filter.WildcardFileFilter

As part of this change the method org.apache.commons.vfs2.FileFilter.accept(FileSelectInfo) now throws a FileSystemException. This change is binary compatible but is not source compatible.
