public void init()

Read initial multicast configuration from mcast store.

terminate

public void terminate()

Clean up when deactivating the application.

processMcastEvent

public void processMcastEvent(org.onosproject.mcast.api.McastEvent event)

Processes the SOURCE_ADDED, SOURCE_UPDATED, SINK_ADDED, SINK_REMOVED, ROUTE_ADDED and ROUTE_REMOVED events.

Parameters:

event - the multicast event to be processed

processPortUpdate

public void processPortUpdate(org.onosproject.net.Device affectedDevice,
