All Implemented Interfaces:
Cloneable, Long2LongMap, Long2LongSortedMap, Map, Serializable, SortedMap

public class Long2LongAVLTreeMap
extends AbstractLong2LongMap
implements Serializable, Cloneable, Long2LongSortedMap

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.
