Class LRUReferenceMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

java.util.LinkedHashMap<K,V>

oracle.adf.share.common.rc.util.impl.LRUReferenceMap<K,V>

Type Parameters:

K -

V -

All Implemented Interfaces:

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

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

This map restricts it's maximum size to be within the capacity passed to the constructor based on removing the least recently used entries. If Reference values are used, null referent's will be removed before considering the LRU on the capacity. Iterators are access ordered.
