speiger.src.collections.objects.maps.abstracts.AbstractObject2ObjectMap<T,V>

speiger.src.collections.objects.maps.impl.tree.Object2ObjectRBTreeMap<T,V>

Type Parameters:

T - the type of elements maintained by this Collection

V - the type of elements maintained by this Collection

All Implemented Interfaces:

java.util.function.Function<T,V>, java.util.Map<T,V>, java.util.NavigableMap<T,V>, java.util.SortedMap<T,V>, Object2ObjectFunction<T,V>, Object2ObjectMap<T,V>, Object2ObjectNavigableMap<T,V>, Object2ObjectSortedMap<T,V>

public class Object2ObjectRBTreeMap<T,V>
extends AbstractObject2ObjectMap<T,V>
implements Object2ObjectNavigableMap<T,V>

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.
