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;
