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.
