### Question:
NeutronOvsdbIidFactory { public static InstanceIdentifier<Node> nodeIid(TopologyId ovsdbTopologyId, NodeId nodeId) { return topologyIid(ovsdbTopologyId).child(Node.class, new NodeKey(nodeId)); }  static InstanceIdentifier<Topology> topologyIid(TopologyId ovsdbTopologyId); static InstanceIdentifier<OvsdbNodeAugmentation> ovsdbNodeAugmentationIid(TopologyId ovsdbTopologyId); static InstanceIdentifier<ExternalGatewayAsL3Endpoint> neutronGbpExternalGatewayIidWildcard(); static InstanceIdentifier<EndpointByPort> endpointByPortIid(UniqueId portId); static InstanceIdentifier<NeutronByGbpMappings> neutronGbpMappingsIidWildcard(); static InstanceIdentifier<Node> nodeIid(TopologyId ovsdbTopologyId, NodeId nodeId); @SuppressWarnings("checkstyle:LineLength") // Longer lines in this method are caused by long package names. static InstanceIdentifier<org.opendaylight.yang.gen.v1.urn.opendaylight.inventory.rev130819.nodes.Node> nodeIid(
            org.opendaylight.yang.gen.v1.urn.opendaylight.inventory.rev130819.NodeId nodeId);  }### Answer:
