Interface BatchBundleListener

All Superinterfaces:

BundleListener, java.util.EventListener

public interface BatchBundleListener
extends BundleListener

A batch BundleEvent listener.

BatchBundleListener is a listener interface that may be implemented by a bundle developer.

A BatchBundleListener object is registered with the Framework using the BundleContext.addBundleListener(org.osgi.framework.BundleListener) method. BatchBundleListener objects are called with a BundleEvent object when a bundle has been installed, resolved, started, stopped, updated, unresolved, or uninstalled.

A BatchBundleListener acts like a BundleListener except the framework will call the batchBegin() method at the beginning of a batch process and call the batchEnd() at the end of a batch process. For example, the framework may notify a BatchBundleListener of a batching process during a refresh packages operation or a resolve bundles operation.

During a batching operation the framework will continue to deliver any events using the BundleListener.bundleChanged(BundleEvent) method to the BatchBundleListener. It is the responsiblity of the BatchBundleListener to decide how to handle events when a batching operation is in progress.

Note that the framework does not guarantee that batching operations will not overlap. This can result in the method batchBegin() being called multiple times before the first batchEnd() is called.

Clients may implement this interface.
