Class NotificationResult

Contents
  • All Implemented Interfaces:
    Serializable

    public class NotificationResult
extends Object
implements Serializable

    Result of a query for buffered notifications. Notifications in a notification buffer have positive, monotonically increasing sequence numbers. The result of a notification query contains the following elements:

    • The sequence number of the earliest notification still in the buffer.
    • The sequence number of the next notification available for querying. This will be the starting sequence number for the next notification query.
    • An array of (Notification,listenerID) pairs corresponding to the returned notifications and the listeners they correspond to.

    It is possible for the nextSequenceNumber to be less than the earliestSequenceNumber. This signifies that notifications between the two might have been lost.

        public TargetedNotification[] getTargetedNotifications()
        Returns the notifications resulting from the query, and the listeners they correspond to.
        Returns:
