Subject Re: Purpose of the file modification date methods in Directory?
Date Fri, 28 Aug 2009 17:32:37 GMT
IndexReader.lastModified returns lastModified of the latest segments_N
file.  Also, IndexCommit exposes a lastModified which is the
lastModified of the segments_N file for that commit point.

Otherwise I don't think Lucene uses it elsewhere.
