public class Object2LongRBTreeMap<T> extends AbstractObject2LongMap<T> implements Object2LongNavigableMap<T>
A Simple Type Specific RB TreeMap implementation that reduces boxing/unboxing. It is using a bit more memory then FastUtil, but it saves a lot of Performance on the Optimized removal and iteration logic. Which makes the implementation actually useable and does not get outperformed by Javas default implementation.
