public interface ApplicationServiceListener extends java.util.EventListener
ApplicationServiceEvent listener. When a ServiceEvent is
fired, it is converted to an ApplictionServiceEvent and it is
synchronously delivered to an ApplicationServiceListener.
ApplicationServiceListener is a listener interface that may be
implemented by an application developer.
An ApplicationServiceListener object is registered with the Framework
using the ApplicationContext.addServiceListener method.
ApplicationServiceListener objects are called with an
ApplicationServiceEvent object when a service is registered,
modified, or is in the process of unregistering.
ApplicationServiceEvent object delivery to
ApplicationServiceListener objects is filtered by the filter
specified when the listener was registered. If the Java Runtime Environment
supports permissions, then additional filtering is done.
ApplicationServiceEvent objects are only delivered to the listener if
the application 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, and the application specified its
dependence on the corresponding service in the application metadata.
ApplicationServiceEvent object delivery to
ApplicationServiceListener objects is further filtered according to
package sources as defined in
ServiceReference.isAssignableTo(Bundle, String).
