        org.eclipse.net4j.util.registry.DelegatingRegistry<K,V>

All Implemented Interfaces:

Map<K,V>, IContainer<Map.Entry<K,V>>, INotifier, ILifecycle, ILifecycle.DeferrableActivation, IRegistry<K,V>

Direct Known Subclasses:

HashMapDelegatingRegistry
```
public abstract class DelegatingRegistry<K,V>
extends Registry<K,V>
```
Implementation note: AbstractDelegatingRegistry does not preserve the "modifyable view" contract of Map.entrySet() as well as of Map.keySet(), i.e. they are disconnected sets and modifications applied to them are not applied to their underlying AbstractDelegatingRegistry.
