    void
    serviceAdded(ServiceDiscoveryEvent event)
    When the cache receives from one of the managed lookup services, an event signaling the registration of a service of interest for the first time (or for the first time since the service has been discarded), the cache invokes the serviceAdded method on all instances of ServiceDiscoveryListener that are registered with the cache; doing so notifies the entity that a service of interest has been discovered.
    void
    serviceChanged(ServiceDiscoveryEvent event)
    When the cache receives, from a managed lookup service, an event signaling the unique modification of the attributes of a service of interest (across the attribute sets of all references to the service), the cache invokes the serviceChanged method on all instances of ServiceDiscoveryListener that are registered with the cache; doing so notifies the entity that the state of a service of interest has changed.
    void
    serviceRemoved(ServiceDiscoveryEvent event)
    When the cache receives, from a managed lookup service, an event signaling the removal of a service of interest from the last such lookup service with which it was registered, the cache invokes the serviceRemoved method on all instances of ServiceDiscoveryListener that are registered with the cache; doing so notifies the entity that a service of interest has been discarded.

    • discovered

      public void discovered(DiscoveryEvent disEvent)
      Description copied from interface: DiscoveryListener
      Called when one or more lookup service registrars has been discovered. The method should return quickly; e.g., it should not make remote calls.
      Specified by:
      discovered in interface DiscoveryListener
      Parameters:
      disEvent - the event that describes the discovered registrars

    • discarded

      public void discarded(DiscoveryEvent e)
      Description copied from interface: DiscoveryListener
      Called when one or more lookup service registrars has been discarded. The method should return quickly; e.g., it should not make remote calls.
      Specified by:
      discarded in interface DiscoveryListener
      Parameters:
      e - the event that describes the discarded registrars

    • serviceAdded

      public void serviceAdded(ServiceDiscoveryEvent event)
      Description copied from interface: ServiceDiscoveryListener
      When the cache receives from one of the managed lookup services, an event signaling the registration of a service of interest for the first time (or for the first time since the service has been discarded), the cache invokes the serviceAdded method on all instances of ServiceDiscoveryListener that are registered with the cache; doing so notifies the entity that a service of interest has been discovered.
      Specified by:
      serviceAdded in interface ServiceDiscoveryListener
      Parameters:
      event - an instance of ServiceDiscoveryEvent containing references to the service item corresponding to the event, including representations of the service's state both before and after the event.

    • getJMXConnection

      public static String getJMXConnection(Entry[] attrs)
      Get the String value found in the JMXConnection entry, or null if the attribute set does not include a JMXConnection

    • serviceRemoved

      public void serviceRemoved(ServiceDiscoveryEvent event)
      Description copied from interface: ServiceDiscoveryListener
      When the cache receives, from a managed lookup service, an event signaling the removal of a service of interest from the last such lookup service with which it was registered, the cache invokes the serviceRemoved method on all instances of ServiceDiscoveryListener that are registered with the cache; doing so notifies the entity that a service of interest has been discarded.
      Specified by:
      serviceRemoved in interface ServiceDiscoveryListener
      Parameters:
      event - a ServiceDiscoveryEvent object containing references to the service item corresponding to the event, including representations of the service's state both before and after the event.

    • serviceChanged

      public void serviceChanged(ServiceDiscoveryEvent event)
      Description copied from interface: ServiceDiscoveryListener
      When the cache receives, from a managed lookup service, an event signaling the unique modification of the attributes of a service of interest (across the attribute sets of all references to the service), the cache invokes the serviceChanged method on all instances of ServiceDiscoveryListener that are registered with the cache; doing so notifies the entity that the state of a service of interest has changed.
      Specified by:

      Parameters:
      event - a ServiceDiscoveryEvent object containing references to the service item corresponding to the event, including representations of the service's state both before and after the event.
