Interface Summary

Interface	Description
DiscoveryAdmin	Methods for controlling which groups a lookup service is a member of, and for controlling which TCP port a lookup service uses for its lookup locator.
LookupCache	The LookupCache interface defines the methods provided by the object created and returned by the ServiceDiscoveryManager when a client-like entity invokes the createLookupCache method.
ServiceDiscoveryListener	The ServiceDiscoveryListener interface defines the methods used by objects such as a LookupCache to notify an entity that events of interest related to the elements of the cache have occurred.
ServiceIDListener	Interface used by a service that does not yet have a service ID, for callback from the JoinManager when a service ID is assigned.
ServiceItemFilter	The ServiceItemFilter interface defines the methods used by an object such as the ServiceDiscoveryManager or the LookupCache to apply additional selection criteria when searching for services in which an entity has registered interest.

Class Summary

Class	Description
JoinManager	A goal of any well-behaved service is to advertise the facilities and functions it provides by requesting residency within at least one lookup service.
JoinManager.AddAttributesTask	Task that asynchronously augments the attributes associated with this join manager's service in the lookup service referenced by the current instance of this class.
JoinManager.Conf
JoinManager.JoinTask	Abstract base class from which all the sub-task classes are derived.
JoinManager.ModifyAttributesTask	Task that asynchronously modifies the attributes associated with this join manager's service in the lookup service referenced by the current instance of this class.
JoinManager.ProxyRegTaskQueue
JoinManager.RegisterTask	Task that asynchronously registers the service associated with this join manager with the lookup service referenced by the current instance of this class.
JoinManager.SetAttributesTask	Task that asynchronously replaces the attributes associated with this join manager's service in the lookup service referenced by the current instance of this class.
ServiceDiscoveryEvent	The ServiceDiscoveryEvent class encapsulates the service discovery information made available by the event mechanism of the LookupCache.
ServiceDiscoveryManager	The ServiceDiscoveryManager class is a helper utility class that any client-like entity can use to "discover" services registered with any number of lookup services of interest.
ServiceDiscoveryManager.CacheTask	Class for implementing register/lookup/notify/dropProxy/discard tasks
ServiceDiscoveryManager.CacheTaskDependencyManager
ServiceDiscoveryManager.CacheTaskWrapper<T>	ObservableFuture wrapper class for CacheTask's.
ServiceDiscoveryManager.EventReg	Data structure used to group together the lease and event sequence number.
ServiceDiscoveryManager.Initializer
ServiceDiscoveryManager.LookupCacheImpl	Internal implementation of the LookupCache interface.
ServiceDiscoveryManager.LookupCacheImpl.ProxyRegDropTask	When the given registrar is discarded, this Task class is used to remove the registrar from the various maps maintained by this cache.
ServiceDiscoveryManager.LookupCacheImpl.RegisterListenerTask	This task class, when executed, first registers to receive ServiceEvents from the given ServiceRegistrar.
ServiceDiscoveryManager.LookupCacheImpl.ServiceDiscardTimerTask	Task class used to determine whether or not to "commit" a service discard request, increasing the chances that the service will eventually be re-discovered.
ServiceDiscoveryManager.LookupCacheImpl.ServiceNotifyDo	Common code for performing service notification to one listener in an executor task thread.
ServiceDiscoveryManager.LookupCacheTerminator	Allows termination of LookupCacheImpl so blocking lookup can return quickly
ServiceDiscoveryManager.ProxyReg	A wrapper class for a ServiceRegistrar.
ServiceDiscoveryManager.ServiceDiscoveryListenerImpl	Class that defines the listener that will receive local events from the internal LookupCache used in the blocking versions of lookup().
ServiceDiscoveryManager.ServiceItemReg	Used in the LookupCache.
