| /** |
| * A batch <code>BundleEvent</code> listener. |
| * |
| * <p> |
| * <code>BatchBundleListener</code> is a listener interface that may be |
| * implemented by a bundle developer. |
| * <p> |
| * A <code>BatchBundleListener</code> object is registered with the |
| * Framework using the {@link BundleContext#addBundleListener} method. |
| * <code>BatchBundleListener</code> objects are called with a |
| * <code>BundleEvent</code> object when a bundle has been installed, resolved, |
| * started, stopped, updated, unresolved, or uninstalled. |
| * <p> |
| * A <code>BatchBundleListener</code> acts like a <code>BundleListener</code> |
| * except the framework will call the {@link #batchBegin()} method at the beginning |
| * of a batch process and call the {@link #batchEnd()} at the end of a batch |
| * process. For example, the framework may notify a <code>BatchBundleListener</code> |
| * of a batching process during a refresh packages operation or a resolve bundles |
| * operation. |
| * <p> |
| * During a batching operation the framework will continue to deliver any events using |
| * the {@link BundleListener#bundleChanged(BundleEvent)} method to the |
| * <code>BatchBundleListener</code>. It is the responsiblity of the |
| * <code>BatchBundleListener</code> to decide how to handle events when a |
| * batching operation is in progress. |
| * <p> |
| * Note that the framework does not guarantee that batching operations will not |
| * overlap. This can result in the method {@link #batchBegin()} being called |
| * multiple times before the first {@link #batchEnd()} is called. |
| * |
| * <p> |
| * Clients may implement this interface. |
| * </p> |
