Interface DataPathEvent

All Superinterfaces:

Event, OpenflowEvent, TypedEvent<OpenflowEventType>

public interface DataPathEvent
extends OpenflowEvent

An OpenFlow Controller DataPath event.

These events are consumed by DataPathListeners who wish to be notified when datapaths connect to, or disconnect from, the controller.

The event types associated with this event are:

• OpenflowEventType.DATAPATH_CONNECTED
• OpenflowEventType.DATAPATH_READY
• OpenflowEventType.DATAPATH_DISCONNECTED
• OpenflowEventType.DATAPATH_REVOKED
• OpenflowEventType.DROPPED_EVENTS_CHECKPOINT

The DATAPATH_CONNECTED event is emitted after handshaking with the device has completed, but before default flows are laid down.

The DATAPATH_READY event is emitted after default flows have been installed on the device.

The DATAPATH_DISCONNECTED event is emitted when a device disconnects from the controller.

The DATAPATH_REVOKED event is emitted in the rare case when a device attempts to connect with a datapath ID that is a duplicate of an already-connected device.

The DROPPED_EVENTS_CHECKPOINT event is a place-holder indicating where in a consumer's event queue events were dropped because of a queue-full condition.
