Class FlowActionUtils

java.lang.Object

org.opendaylight.vtn.manager.internal.util.flow.action.FlowActionUtils

public final class FlowActionUtils
extends Object

FlowActionUtils class is a collection of utility class methods for flow action handling.

Note that this class assumes that:

• Every flow instruction list contains only one APPLY_ACTION list.
• OUTPUT action is always the last element of the flow action list.

Method Detail

getOutputPort

public static String getOutputPort(List<org.opendaylight.yang.gen.v1.urn.opendaylight.action.types.rev131112.action.list.Action> actions)

Return the output port configured in the given action list.

Parameters:

actions - A list of MD-SAL actions.

Returns:

A MD-SAL node connector identifier which specifies the output switch port. null if not found.

getDestinationHost

public static L2Host getDestinationHost(List<org.opendaylight.yang.gen.v1.urn.opendaylight.action.types.rev131112.action.list.Action> actions,
                                        org.opendaylight.yang.gen.v1.urn.ietf.params.xml.ns.yang.ietf.yang.types.rev130715.MacAddress mac,
                                        int vlan)

Return the destination host configured in the given action list.

Parameters:

actions - A list of MD-SAL actions.

mac - The destination MAC address specified by the ingress flow entry.

vlan - The VLAN ID specified by the ingress flow entry.

Returns:

A L2Host instance if found. null if not found.

getActions

public static List<org.opendaylight.yang.gen.v1.urn.opendaylight.action.types.rev131112.action.list.Action> getActions(org.opendaylight.yang.gen.v1.urn.opendaylight.flow.types.rev131026.InstructionList insts,
                                                                                                                       Comparator<org.opendaylight.yang.gen.v1.urn.opendaylight.action.types.rev131112.Ordered> comp)

Return the action list configured in the given flow instructions.

Note that this method returns unmodifiable list.

Parameters:

insts - An InstructionList instance.

comp - Comparator for MD-SAL actions. If null is specified, this method returns unsorted list.

Returns:

A list of Action instances.

toVtnFlowActions

public static List<VtnFlowAction> toVtnFlowActions(List<org.opendaylight.yang.gen.v1.urn.opendaylight.action.types.rev131112.action.list.Action> actions,
                                                   Comparator<? super org.opendaylight.yang.gen.v1.urn.opendaylight.action.types.rev131112.action.list.Action> comp,
                                                   Short ipproto)
                                            throws RpcException

Parameters:

actions - A list of Action instances.

comp - A comparator for the given list.

ipproto - An IP protocol number configured in the flow match.

Returns:

A list of VtnFlowAction instances.

Throws:
