public class Char2CharAVLTreeMap
extends AbstractChar2CharSortedMap
implements Serializable, Cloneable

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.
