A ServiceEvent
listener.
ServiceListener
is a listener interface that may be implemented by a bundle
developer.
A ServiceListener
object is registered with the Framework using the
BundleContext.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. 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.
ServiceEvent
object delivery to ServiceListener
objects is
further filtered according to package sources as defined in
ServiceReference.isAssignableTo(Bundle, String)
.
