IS-Notification

Design

The IS-Notification is a library that provides a subscription/notification mechanism based on Remote Events. This library helps the clients to interact with the Notifier Service and allows:

• for a Client or a Service (Subscriber) to subscribe for a Topic and receiving notifications
• for a Service (producer) to register its own topic and sending notification.

Interface

• public <T extends BaseNotificationConsumer> void registerToISNotification(T consumer,List<GCUBENotificationTopic> notifications, GCUBESecurityManager manager, GCUBEScope ... scope) throws ISNotifierException – this method registers a entity of type T (consumer) for a list of GCUBENotificationTopic in selected Scopes (scope) with a GCUBESecurityManager (manager) in the IS-Notifier;
• public void unregisterFromISNotification( GCUBESecurityManager manager, List<GCUBENotificationTopic> notifications, GCUBEScope ... scope) throws ISNotifierException – this method unregisters the consumer for a list of GCUBENotificationTopic from the IS-Notifier in the selected scopes (scope) with a GCUBESecurityManager (manager);
• public void registerISNotification (EndpointReferenceType producerEPR, List<? extends Topic> notifications, GCUBESecurityManager manager, GCUBEScope ... scope) throws ISNotifierException – this method registers the reference to a resource (producerEPR) that produces a list of topics (notifications) in the IS-Notifier in the selected scopes (scope) with a GCUBESecurityManager (manager);
• public void unregisterISNotification (EndpointReferenceType producerEPR, List<? extends Topic> notifications, GCUBESecurityManager manager, GCUBEScope ... scope) throws ISNotifierException – this method unregister the reference to a resource (producerEPR) for a list of topics (notifications) in the IS-Notifier in the selected scopes (scope) with a GCUBESecurityManager (manager);
• public boolean[] isTopicRegistered(GCUBESecurityManager securityManager, GCUBEScope scope, List<TopicData> topics) throws ISNotifierException - this methods checks if a topic (topic) registration is completed or not for a producer (producerEpr) in the IS-Notifier in the selected scopes (scope) with a GCUBESecurityManager (manager);
