## Package net.jini.discovery

These are utility classes and interfaces that conform to the discovery and join protocol defined in the Jini(TM) Discovery and Join Specification.

See:
Description

Interface Summary
DiscoveryChangeListener | This interface must be implemented by entities that wish to receive notification of the following events.
DiscoveryGroupManagement | This interface defines methods and constants related to the management of the sets of lookup services that are to be discovered using the multicast discovery protocol; that is, lookup services that are discovered by way of group discovery.
DiscoveryListener | This interface must be implemented by parties that wish to obtain notifications from a LookupDiscovery object.
DiscoveryLocatorManagement | This interface defines methods related to the management of the set of lookup services that are to be discovered using the unicast discovery protocol; that is, lookup services that are discovered by way of locator discovery.
DiscoveryManagement | This interface defines methods related to the discovery event mechanism and discovery process termination.
LookupDiscoveryRegistration | When a client requests a registration with a lookup discovery service, an instance of this interface is returned.
LookupDiscoveryService | Defines the interface to the lookup discovery service.

Class Summary
Constants | A holder class for constants that pertain to the unicast and multicast discovery protocols.
ConstrainableLookupLocator | `LookupLocator` subclass which supports constraint operations through the `RemoteMethodControl` interface.
ConstrainableLookupLocatorTrustVerifier | Trust verifier for `ConstrainableLookupLocator` instances.
DiscoveryEvent | Event object passed (via either the `DiscoveryListener` interface or the `DiscoveryChangeListener`) to indicate to interested parties that one or more `ServiceRegistrar` objects have been discovered or discarded during the discovery process.
DiscoveryPermission | Permission for using LookupDiscovery.
IncomingMulticastAnnouncement | Encapsulate the details of unmarshaling an incoming multicast announcement packet.
IncomingMulticastRequest | Encapsulate the details of unmarshaling an incoming multicast request packet.
IncomingUnicastRequest | Encapsulate the details of unmarshaling an incoming unicast request.
IncomingUnicastResponse | This class encapsulates the details of unmarshaling an incoming unicast response.
LookupDiscovery | This class is a helper utility class that encapsulates the functionality required of an entity that wishes to employ multicast discovery to find lookup services located within the entity's "multicast radius" (roughly, the number of hops beyond which neither the multicast requests from the entity, nor the multicast announcements from the lookup service, will propagate).
LookupDiscoveryManager | This class is a helper utility class that organizes and manages all discovery-related activities on behalf of a client or service.
LookupLocatorDiscovery | This class encapsulates the functionality required of an entity that wishes to employ the unicast discovery protocol to discover a lookup service.
OutgoingMulticastAnnouncement | Encapsulate the details of marshaling a multicast announcement into one or more packets.
OutgoingMulticastRequest | Encapsulate the details of marshaling a multicast request into one or more packets.
OutgoingUnicastRequest | Encapsulate the details of marshaling a unicast request.
OutgoingUnicastResponse | Encapsulate the details of marshaling a unicast response.
RemoteDiscoveryEvent | Whenever the lookup discovery service discovers or discards a lookup service matching the discovery/discard criteria of one or more of its registrations, the lookup discovery service sends an instance of this class to the listener corresponding to each such registration.

Exception Summary
LookupUnmarshalException | When unmarshalling an instance of `MarshalledObject`, different exceptions can occur.
