Class WeakValueHashMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

de.hybris.platform.util.WeakValueHashMap<K,V>

All Implemented Interfaces:

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

public class WeakValueHashMap<K,V>
extends java.util.AbstractMap<K,V>
implements java.io.Serializable

A Map implementation that maps keys to weakly referenced values. Keys in this map must be non-null Object objects. Values must be non-null. See java.util.WeakHashMap in the Java API, which has weak keys instead of weak values.
