Interface ControllerMx

public interface ControllerMx

Provides a management API to the OpenFlow Core Controller.

This interface provides for:

• requesting a list of currently registered OpenflowListeners
• setting a RegistrationListener to be notified when OpenflowListeners are added to or removed from the controller
• the acquisition of a TxRxControl from which the recording of transmitted and received OpenFlow messages can be enabled.

Method Summary

Methods

Modifier and Type	Method and Description
void	clearRegistrationListener(RegistrationListener listener) Clears the registration listener from the controller.
Set<DataPathDetails>	getAllDataPathDetails() Returns detailed information describing each of the OpenFlow datapaths connected to the controller, including information about auxiliary connections.
Set<OpenflowListener<?>>	getAllListeners() Returns the set of all currently registered OpenflowListeners.
DataPathDetails	getDataPathDetails(DataPathId dpid) Returns detailed information describing a specific OpenFlow datapath, including information about its auxiliary connections.
int	getOpenflowListenPort() Returns the configured Open Flow port
TxRxControl	getTxRxControl() Returns a reference to the TX/RX message queue control.
void	setRegistrationListener(RegistrationListener listener) Sets the specified registration listener on the controller.
void	startIOProcessing() Starts the controller IO Processing loop.
void	stopIOProcessing() Stops the controller IO Processing loop.

Method Detail

getAllListeners

Set<OpenflowListener<?>> getAllListeners()

Returns the set of all currently registered OpenflowListeners.

Returns:

the set of currently registered OpenFlow listeners

setRegistrationListener

void setRegistrationListener(RegistrationListener listener)

Sets the specified registration listener on the controller. If a registration listener is already set, an exception is thrown.

Parameters:

listener - the listener to be set

Throws:

NullPointerException - if listener is null

IllegalStateException - if a listener is already set

clearRegistrationListener

void clearRegistrationListener(RegistrationListener listener)

Clears the registration listener from the controller. The listener that was set must be passed to this method, to prevent anyone from simply clearing the listener. If the listener is already cleared, or is not the currently set listener, this method does nothing.

Parameters:

listener - the listener to be cleared

Throws:

NullPointerException - if listener is null

getTxRxControl

TxRxControl getTxRxControl()

Returns a reference to the TX/RX message queue control.

Returns:

the TX/RX queue control

getAllDataPathDetails

Set<DataPathDetails> getAllDataPathDetails()

Returns detailed information describing each of the OpenFlow datapaths connected to the controller, including information about auxiliary connections.

Returns:

detailed information about all connected datapaths

getDataPathDetails

DataPathDetails getDataPathDetails(DataPathId dpid)

Returns detailed information describing a specific OpenFlow datapath, including information about its auxiliary connections. This may be null, if no such OpenFlow datapath is currently connected.

Parameters:

dpid - the datapath id

Returns:

detailed information describing the corresponding datapath

Throws:

NullPointerException - if dpid is null

startIOProcessing

void startIOProcessing()

Starts the controller IO Processing loop.

stopIOProcessing

void stopIOProcessing()

Stops the controller IO Processing loop.

getOpenflowListenPort

int getOpenflowListenPort()

Returns the configured Open Flow port

Returns:

the open flow port
