------------------------------------
Summary: 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.
