/**
 * A <code>BundleEvent</code> listener. <code>BundleListener</code> is a
 * listener interface that may be implemented by a bundle developer. When a
 * <code>BundleEvent</code> is fired, it is asynchronously delivered to a
 * <code>BundleListener</code>. The Framework delivers
 * <code>BundleEvent</code> objects to a <code>BundleListener</code> in
 * order and must not concurrently call a <code>BundleListener</code>.
 * <p>
 * A <code>BundleListener</code> object is registered with the Framework using
 * the {@link BundleContext#addBundleListener} method.
 * <code>BundleListener</code>s are called with a <code>BundleEvent</code>
 * object when a bundle has been installed, resolved, started, stopped, updated,
 * unresolved, or uninstalled.
