Constructor Detail

NotificationRequestMessage

public NotificationRequestMessage(long clientSequenceNumber,
                                  int maxNotifications,
                                  long timeout)

Constructs a NotificationRequestMessage object. The behavior is unspecified if any of the parameters is negative.

Parameters:

clientSequenceNumber - the first sequence number that the client is interested in. If negative, it is interpreted as meaning the sequence number that the next notification will have.

maxNotifications - the maximum number of different notifications to return. The TargetedNotification array in the NotificationResponseMessage can have more elements than this if the same notification appears more than once.

timeout - the maximum time in milliseconds to wait for a notification to arrive. This can be 0 to indicate that the method should not wait if there are no notifications, but should return at once. It can be Long.MAX_VALUE to indicate that there is no timeout.
