Interface NotifBook.NotificationDescriptionHandler

Enclosing class:

NotifBook

public static interface NotifBook.NotificationDescriptionHandler

This Java interface must be implemented by classes that filter notification descriptions. This is needed when you need to search in the Notification Book for a specific notification description based on its attributes. Here is an implementation filtering all the notification descriptions but the notification with 'FAILURE' as level:

   public boolean handle(NotificationDescription desc) {
       if (desc == null) {
          throw new IllegalArgumentException("null argument 'desc'");
       }
       if (desc.getSeverityLevel() ==  NotificationLevel.FAILURE) {
           failureNotification.add(desc);
       }
       // return true because all the notification descriptions must be checked.
       return true;
   }
   private List failureNotification = new ArrayList();
 

Another example to search a notification description by its name:

   public void setNotificationName(String name) {
       this.notificationName = name;
   }
   public boolean handle(NotificationDescription desc) {
       if (notificationName == null) {
           throw new IllegalArgumentException("null argument 'desc'");
       }
       if (desc.getName().equalsIgnoreCase(notificationName)) {
           description = desc;
           return false;
       }
       return true;
   }
   private NotificationDescription description = null;
   private String notificationName;
