Class AbstractNotificationHandler<T>

java.lang.Object

com.sun.nio.sctp.AbstractNotificationHandler<T>

All Implemented Interfaces:

NotificationHandler<T>

public class AbstractNotificationHandler<T>
extends Object
implements NotificationHandler<T>

A skeletal handler that consumes notifications and continues.

This class trivially implements the handleNotification methods to return CONTINUE so that all notifications are consumed and the channel continues to try and receive a message.

It also provides overloaded versions of the handleNotification methods, one for each of the required supported notification types, AssociationChangeNotification, PeerAddressChangeNotification, SendFailedNotification, and ShutdownNotification. The appropriate method will be invoked when the notification is received.

Since:

1.7
