Class CachedHashMap<E,F>

java.lang.Object

java.util.AbstractMap<E,F>

java.util.HashMap<E,F>

jmt.framework.data.CachedHashMap<E,F>

All Implemented Interfaces:

Serializable, Cloneable, Map<E,F>

public class CachedHashMap<E,F>
extends HashMap<E,F>

Created by IntelliJ IDEA. User: orsotronIII Date: 28-giu-2005 Time: 17.07.42 This class is an optimized version of an HashMap. Optimization is focused on multiple acesses. This implementation provides a single-element cache for speed-up of data search operations, in particular the most recently requested element is stored to assure a faster search.
