Method Detail

buildFlowKeyName

public String buildFlowKeyName(String scfName,
                               String aclName,
                               String aceName,
                               String type)

Build the name of the FlowKey given the names of the classifier, ACL, ACE, and the type of flow.

Parameters:

scfName - the name of the classifier

aclName - the name of the ACL

aceName - the name of the ACE

type - the type of flow. The possible types are: 'in', 'out', and 'relay'

Returns:

the name which will be given to the flow object

getInterfaceNameFromClassifier

public Optional<String> getInterfaceNameFromClassifier(SclServiceFunctionForwarder theClassifier)

Get the name of the interface we want to classify.

Parameters:

theClassifier - the classifier from which we want the InterfaceName

Returns:

the InterfaceName as a String, if present

deleteFlowFromTable

public FlowDetails deleteFlowFromTable(String nodeName,
                                       String flowKey,
                                       short tableID)

Deletes flow from table.

Parameters:

nodeName - the node from which the flow will be deleted

flowKey - the key of the flow we want to delete

tableID - the table from which we want to delete the flow

Returns:

the FlowDetails object that identifies the desired flow

addRspRelatedFlowIntoNode

public FlowDetails addRspRelatedFlowIntoNode(String nodeName,
                                             org.opendaylight.yang.gen.v1.urn.opendaylight.flow.inventory.rev130819.tables.table.FlowBuilder flow,
                                             long rspId)

Adds RSP related.

Parameters:

nodeName - the node in which the flow will be installed

flow - the flow to install

rspId - the RSP path ID to which the flow belongs to

Returns:

the FlowDetails object that identifies the desired flow

usesLogicalInterfaces

public boolean usesLogicalInterfaces(ServiceFunctionForwarder theSff)

Uses Logical Interfaces.

Parameters:

theSff - the ServiceFunctionForwarder to which the classifier is connected to

Returns:

true if theSff utilizes logical interfaces, false otherwise

extractAcl

public Optional<org.opendaylight.yang.gen.v1.urn.ietf.params.xml.ns.yang.ietf.access.control.list.rev160218.access.lists.Acl> extractAcl(ServiceFunctionClassifier scf)

Extract ACL.

Parameters:

scf - the SCF classifier object

Returns:

the ACL object, if found
