Class ReferenceValueHashMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

org.jboss.util.collection.ReferenceValueMap<K,V>

org.jboss.util.collection.ReferenceValueHashMap<K,V>

Type Parameters:

K - the key type

V - the value type

All Implemented Interfaces:

Map<K,V>

Direct Known Subclasses:

SoftValueHashMap, WeakValueHashMap
