Class LookupHandler

java.lang.Object
  com.gigaspaces.grid.lookup.LookupHandler

All Implemented Interfaces:

java.util.EventListener, net.jini.discovery.DiscoveryListener

public class LookupHandler
extends java.lang.Object
implements net.jini.discovery.DiscoveryListener

The LookupHandler provides autonomic support for handling Jini Lookup Service activation. The LookupHandler creates a LookupDiscovery class which uses multicast to find lookup services.

If lookup service(s) have not been discovered in an amount of time determined by a random number generator, this utility will start an instance of a Jini Lookup Service (reggie) with member groups obtained from this utility's configuration.

Conversely, if the instantiated LookupDiscovery instance notifies the DiscoveryListener of a discarded lookup service, this utility will verify that the requisite number of Jini Lookup Services exist, and if they do not, schedule the creation of an instance of a Jini Lookup Service (reggie) with member groups obtained from this utility's configuration.
