Class SoftHashMap<K,V>

java.lang.Object
  extended by java.util.AbstractMap<K,V>
      extended by com.alee.utils.map.SoftHashMap<K,V>
All Implemented Interfaces:
java.io.Serializable, java.util.Map<K,V>

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

Map implementation that holds soft references its values. This map might be useful to hold memory-sensitive cache.
