it.unimi.dsi.fastutil.objects.Object2ObjectAVLTreeMap<K,V>
public class Object2ObjectAVLTreeMap<K,V>
A type-specific AVL tree map with a fast, small-footprint implementation.
The iterators provided by the views of this class are type-specific bidirectional iterators.
Moreover, the iterator returned by iterator()
can be safely cast
to a type-specific list iterator.

Object2ObjectMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Object2ObjectMap.entrySet()
so that it returns an ObjectSet
of objects of type Object2ObjectMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
