void event(ServiceEvent event, java.util.Map<BundleContext,java.util.Collection<ListenerHook.ListenerInfo>> listeners)Event listener hook method.

event- The service event to be delivered.
listeners- A map of Bundle Contexts to a collection of Listener Infos for the bundle's listeners to which the specified event will be delivered. The implementation of this method may remove bundle contexts from the map and listener infos from the collection values to prevent the event from being delivered to the associated listeners. The map supports all the optional
putAll. Attempting to add to the map will result in an
UnsupportedOperationException. The collection values in the map supports all the optional
addAll. Attempting to add to a collection will result in an
