Method Detail

transitionToMaster

public void transitionToMaster()

Description copied from interface: IHAListener

This notification is fired if the controller's initial role was SLAVE and the controller is now transitioning to MASTER. Modules need to read their initial role in startUp from floodlight provider.

Specified by:

transitionToMaster in interface IHAListener

controllerNodeIPsChanged

public void controllerNodeIPsChanged(java.util.Map<java.lang.String,java.lang.String> curControllerNodeIPs,
                                     java.util.Map<java.lang.String,java.lang.String> addedControllerNodeIPs,
                                     java.util.Map<java.lang.String,java.lang.String> removedControllerNodeIPs)

Description copied from interface: IHAListener

Gets called when the IP addresses of the controller nodes in the controller cluster change. All parameters map controller ID to the controller's IP.

Specified by:

controllerNodeIPsChanged in interface IHAListener

Parameters:

curControllerNodeIPs - The current mapping of controller IDs to IP

addedControllerNodeIPs - These IPs were added since the last update

removedControllerNodeIPs - These IPs were removed since the last update

getName

public java.lang.String getName()

Description copied from interface: IListener

The name assigned to this listener

Specified by:

getName in interface IListener<HAListenerTypeMarker>

Returns:

isCallbackOrderingPrereq

public boolean isCallbackOrderingPrereq(HAListenerTypeMarker type,
                                        java.lang.String name)

Description copied from interface: IListener

Check if the module called name is a callback ordering prerequisite for this module. In other words, if this function returns true for the given name, then this listener will be called after that message listener.

Specified by:

isCallbackOrderingPrereq in interface IListener<HAListenerTypeMarker>

Parameters:

type - the object type to which this applies

name - the name of the module

Returns:

whether name is a prerequisite.

isCallbackOrderingPostreq

public boolean isCallbackOrderingPostreq(HAListenerTypeMarker type,
                                         java.lang.String name)

Description copied from interface: IListener

Check if the module called name is a callback ordering post-requisite for this module. In other words, if this function returns true for the given name, then this listener will be called before that message listener.

Specified by:

isCallbackOrderingPostreq in interface IListener<HAListenerTypeMarker>

Parameters:

type - the object type to which this applies

name - the name of the module

Returns:

whether name is a post-requisite.
