Class NullValueAwareConcurrentHashMap<K,V>

java.lang.Object
  java.util.AbstractMap<K,V>
      java.util.concurrent.ConcurrentHashMap<K,V>
          org.apache.myfaces.extensions.validator.util.NullValueAwareConcurrentHashMap<K,V>

All Implemented Interfaces:

Serializable, ConcurrentMap<K,V>, Map<K,V>

public class NullValueAwareConcurrentHashMap<K,V>
extends ConcurrentHashMap<K,V>

in some cases we have to store null values to avoid re-evaluation
