public final class ClearNodeFlowsTask
extends RunnableVTNFuture<Void>
implements StatsReaderCallback

ClearNodeFlowsTask describes a task which uninstalls VTN flow entries present in the given switch.

This task will remove only flow entries installed by the VTN Manager, and will keep flow entries installed by another component. Note that this task never removes table miss flow entries from OF1.3 switches.
