Method Detail

reconcileFlows

IListener.Command reconcileFlows(java.util.ArrayList<OFMatchReconcile> ofmRcList)

Given an input OFMatch, this method applies the policy of the reconciler and returns a the same input OFMatch structure modified. Additional OFMatches, if needed, are returned in OFMatch-list. All the OFMatches are assumed to have "PERMIT" action.

Parameters:

ofmRcList - input flow matches, to be updated to be consistent with the policies of this reconciler Additional OFMatch-es can be added to the "list" as needed. For example after a new ACL application, one flow-match may result in multiple flow-matches The method must also update the ReconcileAction member in ofmRcList entries to indicate if the flow needs to be modified, deleted or left unchanged OR of a new entry is to be added after flow reconciliation

Returns:

Command.CONTINUE if the OFMatch should be sent to the next flow reconciler. Command.STOP if the OFMatch shouldn't be processed further. In this case the no reconciled flow-mods would be programmed
