ServiceEvent
listener.
When a ServiceEvent
is fired, it is synchronously delivered to a BundleListener
.
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).
