[PR] GH-3900: misc mem improvements [jena]
arne-bdt opened a new pull request, #3901:
URL: https://github.com/apache/jena/pull/3901
GitHub issue resolved #3900
Pull request Description:
Minor bugs fixed:
- FastArrayBunch does not hold references to orphans after #tryRemove and #removeUnchecked
- FastHashMap#computeIfAbsent does not creat an invalid state if call of absentValueSupplier fails
- FastHashMap#compute now grows on insert like all other insert operations of this map
Improvements:
- iterators and spliterators don't need a runnable for concurrency check any more. They check the size directly, which has been shown to be faster.
- FastHashBase#fillPositionsArray now iterates over the dense keys array, which should be faster in most cases.
- Removed FastHashSet#IndexedKey and the corresponding iterator and spliterator implementations --> introduced FastHashBase#forEachKey and #forEachKeyParallel instead
- added JavaDoc
- added tests
