Method Detail

initialize

protected void initialize()

Description copied from class: OFModule

method that initializes this module. Subclass of OFModule must implement this method. You can find the example of this method in OFMLinkDiscovery.initialize().

Specified by:

initialize in class OFModule

handleHandshakedEvent

protected boolean handleHandshakedEvent(Connection conn,
                            MessageContext context)

Description copied from class: OFModule

An abstract method that all subclasses should implement. This method is called after FEATURE-REQUEST and FEATURE-REPLY is correct exchanged, by OFModule.processHandshakeFinished(Connection, MessageContext). Normally, most of modules have very simple implementation for this method, only returning true.

Specified by:

handleHandshakedEvent in class OFModule

Parameters:

conn - connection that the event has occurred

context - message context for the handshaking messages

Returns:

true is returned when the event has been correctly processed. false otherwise.

handleMessage

protected boolean handleMessage(Connection conn,
                    MessageContext context,
                    org.openflow.protocol.OFMessage msg,
                    java.util.List<org.openflow.protocol.OFMessage> outgoing)

Description copied from class: OFModule

Handle incoming messages that pass the test of filters. All subclasses of OFModule must implement this method. This method is called by OFModule.processMessage(Connection, MessageContext, OFMessage, List).

Specified by:

handleMessage in class OFModule

Parameters:

conn - connection that the message has arrived

context - message context for the message

msg - the actual message object

outgoing - responses for the message arrived, which is filled by the handleMessage implementation

Returns:

true if the message has been correctly processed. false otherwise.

handleDisconnect

protected boolean handleDisconnect(Connection conn)

Description copied from class: OFModule

Process the disconnection event from a switch. This callback method is called by OFModule.processDisconnect(Connection). All subclasses of OFModule should implement this method.

Specified by:

handleDisconnect in class OFModule

Parameters:

conn - connection that the event has occurred

Returns:

true if the event has been correctly processed. false otherwise.

getModels

public OFModel[] getModels()

Description copied from class: OFModule

returns the array of all OFModel objects associated with this module. Normally the size of the array is one, but not limited to.

Specified by:

getModels in class OFModule

Returns:

the array of OFModel objects
