public class Float2ObjectAVLTreeMap
extends AbstractFloat2ObjectSortedMap
implements Serializable, Cloneable, Float2ObjectSortedMap

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.

Method Detail

put

public Object put(float k,
                  Object v)
Description copied from interface: Float2ObjectMap
Adds a pair to the map.

Specified by:
put in interface Float2ObjectMap
Overrides:
put in class AbstractFloat2ObjectMap

remove

public Object remove(float k)
Description copied from interface: Float2ObjectMap
Removes the mapping with the given key.

Specified by:
remove in interface Float2ObjectMap
Overrides:
remove in class AbstractFloat2ObjectMap

put

public Object put(Object ok,
                  Object ov)
Description copied from class: AbstractFloat2ObjectMap
Delegates to the corresponding type-specific method, taking care of returning null on a missing key.

This method must check whether the provided key is in the map using containsKey(). Thus, it probes the map twice. Implementors of subclasses should override it with a more efficient method.

Specified by:
put in interface Map
Overrides:
put in class AbstractFloat2ObjectMap

remove

public Object remove(Object ok)
Description copied from class: AbstractFloat2ObjectMap
Delegates to the corresponding type-specific method, taking care of returning null on a missing key.

This method must check whether the provided key is in the map using containsKey(). Thus, it probes the map twice. Implementors of subclasses should override it with a more efficient method.

Specified by:
remove in interface Map
Overrides:
remove in class AbstractFloat2ObjectMap

containsValue

clear

public void clear()
Specified by:
clear in interface Map
Overrides:
clear in class AbstractFloat2ObjectMap

containsKey

Returns:
a type-specific sorted set view of the keys contained in this map.

clone

public Object clone()
