it.unimi.dsi.fastutil.shorts.Short2IntAVLTreeMap
public class Short2IntAVLTreeMap
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.

This method must check whether the provided key is in the map using containsKey()
. Thus,
it probes the map twice. Implementors of subclasses should override it with a more efficient method.

Short2IntMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Short2IntMap.entrySet()
so that it returns an ObjectSet
of objects of type Short2IntMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
