| /** |
| * A {@code ServiceEvent} listener that does not filter based upon |
| * package wiring. {@code AllServiceListener} is a listener interface |
| * that may be implemented by a bundle developer. When a |
| * {@code ServiceEvent} is fired, it is synchronously delivered to an |
| * {@code AllServiceListener}. The Framework may deliver |
| * {@code ServiceEvent} objects to an {@code AllServiceListener} |
| * out of order and may concurrently call and/or reenter an |
| * {@code AllServiceListener}. |
| * <p> |
| * An {@code AllServiceListener} object is registered with the Framework |
| * using the {@code BundleContext.addServiceListener} method. |
| * {@code AllServiceListener} objects are called with a |
| * {@code ServiceEvent} object when a service is registered, modified, or |
| * is in the process of unregistering. |
| * |
| * <p> |
| * {@code ServiceEvent} object delivery to |
| * {@code AllServiceListener} 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} |
| * objects are only delivered to the listener if the bundle which defines the |
| * listener object's class has the appropriate {@code ServicePermission} |
| * to get the service using at least one of the named classes under which the |
| * service was registered. |
| * |
| * <p> |
| * Unlike normal {@code ServiceListener} objects, |
| * {@code AllServiceListener} objects receive all |
| * {@code ServiceEvent} objects regardless of 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. |
