Use FileFilter instead of FileNameFilter in FSDirectory.listAll
---------------------------------------------------------------
Key: LUCENE-3132
URL: https://issues.apache.org/jira/browse/LUCENE-3132
Project: Lucene - Java
Issue Type: Improvement
Reporter: Shai Erera
Assignee: Shai Erera
Priority: Trivial
Fix For: 3.2, 4.0
FSDirectory.listAll() uses FileNameFilter, but all it does is check whether the File + name
given denotes a directory. For that, it does new File(dir, file).isDirectory(). If we use
FileFilter, new File() won't be necessary. This is a trivial thing, I'll post a patch soon.
