public class MapBasedDictionary<K,V> extends Dictionary<K,V> implements Map<K,V>
LinkedHashMap
is used, if no Map is specified.
This implementation will enforce the Dictionary behaviour over the map when
it comes to handling null values. As opposed to a Map, the Dictionary always
throws NullPointerException
if a given argument is null.Map
