Examples of org.gudy.azureus2.core3.util.LightHashMap$HashIterator

org.gudy.azureus2.core3.util.protocol.AzURLStreamHandlerFactory
A lighter (on memory) hash map
Advantages over HashMap:
- Lower memory footprint
- Everything is stored in a single array, this might improve cache performance (not verified)
- Read-only operations on Key and Value iterators should be concurrency-safe (Entry iterators are not) 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
- concurrent modification detection is not as fail-fast as HashMap as no modification counter is used and only structural differences are noted
