public interface ServiceListener
extends EventListener

A ServiceEvent listener. ServiceListener is a listener interface that may be implemented by a module developer. When a ServiceEvent is fired, it is synchronously delivered to a ServiceListener. The Runtime may deliver ServiceEvent objects to a ServiceListener out of order and may concurrently call and/or reenter a ServiceListener.

A ServiceListener object is registered with the Runtime using the ModuleContext.addServiceListener method. ServiceListener objects are called with a ServiceEvent object when a service is registered, modified, or is in the process of unregistering.

ServiceEvent object delivery to ServiceListener objects is filtered by the filter specified when the listener was registered.

ServiceEvent object delivery to ServiceListener objects is filtered according to package sources as defined in ServiceReference.isAssignableTo(Module, String).
