Class ValuesTable<K,V>

java.lang.Object

com.alee.utils.collection.ValuesTable<K,V>

All Implemented Interfaces:

java.io.Serializable

@XStreamConverter(value=ValuesTableConverter.class)
public class ValuesTable<K,V>
extends java.lang.Object
implements java.io.Serializable

This class allows you to create key-value table from which you can either request a key by value or a value by key. Both key and value should be unique and adding same key or value will replace existing one in the lists.
