------------------------------------
Summary: Add a set iterator to SentinalIntSet
Key: LUCENE-4881
URL: https://issues.apache.org/jira/browse/LUCENE-4881
Project: Lucene - Core
Issue Type: Improvement
Reporter: David Smiley
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 add.
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
http://lucene.472066.n3.nabble.com/IntHashSet-SentinelIntSet-SortedIntDocSet-td4037516.html
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.
