All Implemented Interfaces:
Cloneable, Double2ObjectMap, Double2ObjectSortedMap, Map, Serializable, SortedMap

public class Double2ObjectAVLTreeMap
extends AbstractDouble2ObjectMap
implements Serializable, Cloneable, Double2ObjectSortedMap

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.

clone

public Object clone()
Returns a deep copy of this tree map.

This method performs a deep copy of this tree map; the data stored in the set, however, is not cloned. Note that this makes a difference only for object keys.
