All Implemented Interfaces:
ClientRegistry, LocalRegistry, Registry

public class BaseClientRegistry
extends BaseOrderedRegistry
implements ClientRegistry

Simple implementation of the ClientRegistry interface.

Extends BaseRegistry implementation to override object creation method and ensure Registry object is synchronized with its persistence backend by delegating actual addition/deletion of objects to the registry service.

To avoid loops, a RegistryService implementation using this class nees to call the addLocalEntry/removeLocalEntry methods to modify the in memory state of this Registry
