Example 1 with FabricUtils

use of org.onosproject.pipelines.fabric.impl.behaviour.FabricUtils in project onos by opennetworkinglab.

the class NextObjectiveTranslator method allGroup.

private int allGroup(NextObjective obj, ObjectiveTranslation.Builder resultBuilder) throws FabricPipelinerException {
    final Collection<DefaultNextTreatment> defaultNextTreatments = defaultNextTreatments(obj.nextTreatments(), true);
    // multicast entries is based solely on the output port.

    // switch interface is associated with only one VLAN, otherwise we would
    // need to support replicating multiple times the same packet for the
    // same port while setting different VLAN IDs. Hence, collect in a set.
    final Set<PortNumber> outPorts = defaultNextTreatments.stream().map(DefaultNextTreatment::treatment).map(FabricUtils::outputPort).filter(Objects::nonNull).collect(Collectors.toSet());

    final int groupId = obj.id();

    // action profile to apply to the groups of ALL type.
