Examples of net.jini.discovery.LookupDiscovery$ResponseListener

net.jini.discovery.LookupDiscovery
Thread that listens for multicast responses to the multicast requests sent out by the Requestor Thread class. Upon receiving a multicast response, the socket that accepted the connection request associated with the the multicast response is added to the set of pendingDiscoveries so that it (the socket) will be used by the UnicastDiscoveryTask to complete the discovery process asynchronously.
Only 1 instance of this thread is run.
