/**
 * A <tt>ServiceEvent</tt> listener.
 *
 * <p><tt>AllServiceListener</tt> is a listener interface that may be implemented by a bundle
 * developer.
 * <p>An <tt>AllServiceListener</tt> object is registered with the Framework using the
 * <tt>BundleContext.addServiceListener</tt> method.
 * <tt>AllServiceListener</tt> objects are called with a <tt>ServiceEvent</tt> object when
 * a service has been registered or modified, or is in the process of unregistering.
 *
 * <p><tt>ServiceEvent</tt> object delivery to <tt>AllServiceListener</tt> objects is filtered by the
 * filter specified when the listener was registered. If the Java Runtime Environment
 * supports permissions, then additional filtering is done.
 * <tt>ServiceEvent</tt> objects are only delivered to the listener if the bundle which defines
 * the listener object's class has the appropriate <tt>ServicePermission</tt> to get the service
 * using at least one of the named classes the service was registered under.
 * 
 * <p>
 * Unlike normal <tt>ServiceListener</tt> objects,
 * <tt>AllServiceListener</tt> objects have all ServiceEvent objects delivered regardless of the
 * package scope of the listening bundle.
 * 
 * @version $Revision: 1.1 $
