Subject [jira] [Resolved] (LUCENE-4881) Add a set iterator to SentinelIntSet
Date Tue, 02 Apr 2013 15:11:16 GMT


David Smiley resolved LUCENE-4881.

    Resolution: Won't Fix

I committed better javadocs, including sample code to iterate the values.

Closing issue as won't fix (for now). If at some point we want an iterator, the patch is here
and it can be re-considered.

> I'm working on code that needs a hash based int Set.  It will need to iterate over the
values, but SentinalIntSet doesn't have this utility feature.  It should be pretty easy to
> FYI this is an out-growth of a question I posed to the dev list, examining 3 different
int hash sets out there: SentinalIntSet, IntHashSet (in Lucene facet module) and the 3rd party
IntOpenHashSet (HPPC) -- see
 I decided to go for SentinalIntSet because it's already in Lucene-core, adding the method
I need should be easy, and it has a nice lean implementation.
