A ServiceEvent
listener.
AllServiceListener
is a listener interface that may be implemented by a bundle
developer.
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 the service was registered under.
Unlike normal ServiceListener
objects,
AllServiceListener
objects receive all ServiceEvent objects regardless of the
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.
