it.unimi.dsi.fastutil.bytes.Byte2ByteRBTreeMap
public class Byte2ByteRBTreeMap
A type-specific red-black 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()

it probes the map twice. Implementors of subclasses should override it with a more efficient method.

Byte2ByteMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Byte2ByteMap.entrySet()
so that it returns an ObjectSet
of objects of type Byte2ByteMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
