+/**
+ * A <code>ServiceEvent</code> listener. <code>ServiceListener</code> is a
+ * listener interface that may be implemented by a bundle developer. When a
+ * <code>ServiceEvent</code> is fired, it is synchronously delivered to a
+ * <code>ServiceListener</code>. The Framework may deliver
+ * <code>ServiceEvent</code> objects to a <code>ServiceListener</code> out
+ * of order and may concurrently call and/or reenter a
+ * <code>ServiceListener</code>.
+ * 
+ * <p>
+ * A <code>ServiceListener</code> object is registered with the Framework
+ * using the <code>BundleContext.addServiceListener</code> method.
+ * <code>ServiceListener</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>ServiceListener</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 under which the service was registered.
+ * 
+ * <p>
+ * <code>ServiceEvent</code> object delivery to <code>ServiceListener</code>
+ * objects is further filtered according to package sources as defined in
+ * {@link ServiceReference#isAssignableTo(Bundle, String)}.
+ *
