public class Long2ByteAVLTreeMap
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.

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