All Classes and Interfaces

Class	Description
AbstractConfiguratorListener	AbstractConfiguratorListener
AbstractRegistry	Provides a fail-safe registry service backed by cache file.
AbstractRegistryFactory	AbstractRegistryFactory.
AbstractRetryTask	AbstractRetryTask
AbstractServiceDiscovery	Each service discovery is bond to one application.
AbstractServiceDiscoveryFactory	Abstract ServiceDiscoveryFactory implementation with cache, the subclass should implement AbstractServiceDiscoveryFactory.createDiscovery(URL) method to create an instance of ServiceDiscovery
CacheableFailbackRegistry	Based on FailbackRegistry, it adds a URLAddress and URLParam cache to save RAM space.
