I'm upgrading some stuff to lucene trunk....  is there any way to get
the last modified date from an AtomicReader?  or an
AtomicReaderContext?

thanks

You need to store this in the IndexCommit.

Ie, when you commit, pass the Map<String,String> userData that holds
the timestamp (and anything else you want to store...).

Or, use DR.getVersion or DR.getIndexCommit().getGeneration() as
similar replacements.

Can you describe how you were using IR.lastModified...?

Hi,

An index directory is always a CompositeReader, so single segment never
knows a modification date, so it's not part of AtomicReader. The only part
that might know anything about index commits, directories,... is
DirectoryReader (see my blog post).

But all that's not the cause for your problem it has nothing to do with my
refactoring, lastModified is broken and was removed by Mike McCandless:
https://issues.apache.org/jira/browse/LUCENE-3672
