@ConsumerType public interface AllServiceListener extends ServiceListener
ServiceEvent listener that does not filter based upon package
wiring. AllServiceListener is a listener interface that may be
implemented by a bundle developer. When a ServiceEvent is fired, it
is synchronously delivered to an AllServiceListener. The Framework
may deliver ServiceEvent objects to an AllServiceListener out
of order and may concurrently call and/or reenter an
AllServiceListener.
An AllServiceListener object is registered with the Framework using
the BundleContext.addServiceListener method.
AllServiceListener objects are called with a ServiceEvent
object when a service is registered, modified, or is in the process of
unregistering.
ServiceEvent object delivery to AllServiceListener 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 appropriate
ServicePermission 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 all ServiceEvent 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.
