java.lang.Object

org.opendaylight.vtn.manager.internal.flow.remove.TenantIndexFlowRemover<NodeFlows>

org.opendaylight.vtn.manager.internal.flow.remove.EdgeNodeFlowRemover

All Implemented Interfaces:

FlowRemover

public final class EdgeNodeFlowRemover
extends TenantIndexFlowRemover<NodeFlows>

An implementation of FlowRemover which removes VTN data flows related to the specified edge network on a switch.

Edge network is specified by a SalNode instance, a PortFilter instance, and a VLAN ID. A SalNode instance specifies the target physical switch. This class scans all VTN data flows related to the specified switch, and removes data flows if the ingress or egress flow entry meets all the following conditions.

• The given VLAN ID is configured in the flow entry.
• The ingress or egress switch port is accepted by the given PortFilter instance.

Note that this method always passes a null as a VtnPort to PortFilter.
