Class KeyValue<K extends Comparable<? super K>,V>

java.lang.Object
  com.samskivert.util.KeyValue<K,V>

All Implemented Interfaces:

Comparable<KeyValue<K,V>>

public class KeyValue<K extends Comparable<? super K>,V>
extends Object
implements Comparable<KeyValue<K,V>>

Used to wrap a key/value pair into an object that behaves like the key but holds on to the value. This might be used to maintain a list of objects sorted by some unrelated key in a SortableArrayList. For example:

 SortableArrayList list = new SortableArrayList();
 Integer key = new Integer(4);
 Object value = ...;
 KeyValue kval = new KeyValue(key, value);
 list.insertSorted(kval);
 // ...
 Integer key = new Integer(4);
 int oidx = list.indexOf(key);
 Object value = (oidx == -1) ? null : list.get(oidx);
 

Field Summary

K	key The key in this key/value pair.
V	value The value in this key/value pair.

Constructor Summary

KeyValue(K key, V value)
Creates a key/value pair with the specified key and value.

Method Summary

int	compareTo(KeyValue<K,V> other)
boolean	equals(Object other)
int	hashCode()
String	toString()
