Method Summary

Modifier and Type	Method and Description
void	addLookupLocatorsChangeListener(LookupLocatorsChangeListener listener)
void	removeLookupLocatorsChangeListener(LookupLocatorsChangeListener listener)
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.

Method Detail

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.

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:

serviceChanged 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.
