| /** |
| * 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. |
