@ConsumerType @FunctionalInterface public interface AllServiceListener extends ServiceListener
AServiceEvent
listener that does not filter based upon package wiring.AllServiceListener
is a listener interface that may be implemented by a bundle developer. When aServiceEvent
is fired, it is synchronously delivered to anAllServiceListener
. The Framework may deliverServiceEvent
objects to anAllServiceListener
out of order and may concurrently call and/or reenter anAllServiceListener
.An
AllServiceListener
object is registered with the Framework using theBundleContext.addServiceListener
method.AllServiceListener
objects are called with aServiceEvent
object when a service is registered, modified, or is in the process of unregistering.ServiceEvent
object delivery toAllServiceListener
objects is filtered by the filter specified when the listener was registered. If the Java Runtime Environment supports permissions, then additional filtering is done.ServiceEvent
objects are only delivered to the listener if the bundle which defines the listener object's class has the appropriateServicePermission
to get the service using at least one of the named classes under which the service was registered.Unlike normal
ServiceListener
objects,AllServiceListener
objects receive allServiceEvent
objects regardless of whether the package source of the listening bundle is equal to the package source of the bundle that registered the service. This means that the listener may not be able to cast the service object to any of its corresponding service interfaces if the service object is retrieved.- Since:
