Event listener hook method. This method is called prior to service event delivery when a publishing module registers, modifies or unregisters a service. This method can filter the listeners which receive the event.

Parameters
eventThe service event to be delivered.
listenersA map of Module Contexts to a list of Listener Infos for the module's listeners to which the specified event will be delivered. The implementation of this method may remove module contexts from the map and listener infos from the list values to prevent the event from being delivered to the associated listeners.
