public class BundleEvent
extends java.util.EventObject

An event from the Framework describing a bundle lifecycle change.

BundleEvent objects are delivered to SynchronousBundleListeners and BundleListeners when a change occurs in a bundle's lifecycle. A type code is used to identify the event type for future extendability.

OSGi Alliance reserves the right to extend the set of types.
