MapBasedDictionary (Gemini Blueprint 1.0.2.RELEASE API)

java.lang.Object
- java.util.Dictionary<K,V>
- - org.eclipse.gemini.blueprint.util.internal.MapBasedDictionary<K,V>

All Implemented Interfaces:

Map<K,V>
```
public class MapBasedDictionary<K,V>
extends Dictionary<K,V>
implements Map<K,V>
```
Dictionary implementation backed by a map instance. While the JDK provides a Dictionary implementation through Hashtable, the class itself is always synchronized and does not maintain the internal order.
This simple wrapper, accepts any type of Map as backing storage allowing more options in choosing the appropriate implementation. By default, a 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.
