| /** |
| * A <code>ServiceEvent</code> listener. |
| * |
| * <p> |
| * <code>AllServiceListener</code> is a listener interface that may be |
| * implemented by a bundle developer. |
| * <p> |
| * An <code>AllServiceListener</code> object is registered with the Framework |
| * using the <code>BundleContext.addServiceListener</code> method. |
| * <code>AllServiceListener</code> objects are called with a |
| * <code>ServiceEvent</code> object when a service is registered, modified, or |
| * is in the process of unregistering. |
| * |
| * <p> |
| * <code>ServiceEvent</code> object delivery to |
| * <code>AllServiceListener</code> objects is filtered by the filter specified |
| * when the listener was registered. If the Java Runtime Environment supports |
| * permissions, then additional filtering is done. <code>ServiceEvent</code> |
| * objects are only delivered to the listener if the bundle which defines the |
| * listener object's class has the appropriate <code>ServicePermission</code> |
| * to get the service using at least one of the named classes the service was |
| * registered under. |
| * |
| * <p> |
| * Unlike normal <code>ServiceListener</code> objects, |
| * <code>AllServiceListener</code> 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. |
| * |
| * @version $Revision: 1.9 $ |
| * @see ServiceEvent |
| * @see ServicePermission |
| * @since 1.3 |
