Interface ErrorEvent

All Superinterfaces:

Event, OpenflowEvent, TypedEvent<OpenflowEventType>

public interface ErrorEvent
extends OpenflowEvent

An OpenFlow Controller Error event. These events are consumed by listeners who have only an indirect link to a controller service, and need to be informed of an exception thrown within controller code from a call made on their behalf.

For example, the SequencedPacketListener only gets to instruct the controller to send a Packet-Out message indirectly, via the boolean return value from its event() callback. If an error occurs during the send, the PacketSequencer will inform the packet listener of the error via its errorEvent() callback.

The event types associated with this event are:

• OpenflowEventType.ERROR
