DefaultNextObjective

@Beta
public interface NextObjective
extends Objective

Represents a nexthop which will be translated by a driver into the appropriate group or actions needed to implement the egress function. A next objective is made up of a collection of traffic treatments associated with a type. These types are: - Hashed - Broadcast - Failover - Simple These types will indicate to the driver what the intended behavior is. For example, a broadcast next objective with a collection of output treatments will indicate to a driver that all output actions are expected to be executed simultaneously. The driver is then free to implement this as a group or a simple action list.

Method Detail

next

java.util.Collection<TrafficTreatment> next()

The collection of treatments that need to be applied to a set of traffic.

Returns:

a collection of traffic treatments

type

NextObjective.Type type()

The type of operation that will be applied to the traffic using the collection of treatments.

Returns:

a type

meta

TrafficSelector meta()

Auxiliary optional information provided to the device driver. Typically conveys information about selectors (matches) that are intended to use this Next Objective.

Returns:

a selector intended to pass meta information to the device driver. Value may be null if no meta information is provided.
