Class IndexedHashMap<I,K,V>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

java.util.LinkedHashMap<K,V>

psdi.util.IndexedHashMap<I,K,V>

Type Parameters:

I -

K -

V -

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map<K,V>

public class IndexedHashMap<I,K,V>
extends java.util.LinkedHashMap<K,V>

A LinkedHashMap that allows you to get the value by position/index. Use this if you want to avoid iterating thru the Map's Values Iterator.
