Examples of LightHashSet

org.gudy.azureus2.core3.util.LightHashSet
A lighter (on memory) hash set
Advantages over HashSet:
- Lower memory footprint
- Everything is stored in a single array, this might improve cache performance (not verified)
- Read-only operations on iterators should be concurrency-safe but they might return null values unexpectedly under concurrent modification (not verified)
Disadvantages:
- removal is implemented with thombstone-keys, this can significantly increase the lookup time if many values are removed. Use compactify() for scrubbing
- entry set iterators and thus transfers to other maps are slower than compareable implementations
- the map does not store hashcodes and relies on either the key-objects themselves caching them (such as strings) or a fast computation of hashcodes
