----------------------------------
Resolution: Fixed
> improve int set utility impls
> -----------------------------
>
> Key: UIMA-4060
> URL: https://issues.apache.org/jira/browse/UIMA-4060
> Project: UIMA
> Issue Type: Bug
> Components: Core Java Framework
> Affects Versions: 2.6.1SDK
> Reporter: Marshall Schor
> Assignee: Marshall Schor
> Priority: Minor
> Fix For: 2.6.1SDK
>
>
> The PositiveIntSet impl has a bug in the ordered set iterator (not
> incrementing an index in a loop). In addition, Improve this also by
> eliminating expensive operations on bit Sets (such as computing the number of
> elements in the set), and augmenting the IntBitSet to allow a potentially
> much smaller footprint, by supporting an "offset" for the use case where
> there's a lot of fairly "dense" members, clustered at an offset from 0.
> Increase the hysteresis for switching among alternative impls in
> PositiveIntSet. Add (approximate) tracking for IntHashSet of mostNegative as
> well as most positive. Do some other minor cleanup - making things
> appropriately private / final. Add / update test cases.
