## org.eclipse.gemini.blueprint.context.event
Interface OsgiBundleApplicationContextEventMulticaster

All Known Implementing Classes:
  OsgiBundleApplicationContextEventMulticasterAdapter

    public interface OsgiBundleApplicationContextEventMulticaster

Interface to be implemented by objects that can manage a number of `OsgiBundleApplicationContextListener`s, and publish events to them.

The contract of this interface is very similar to that of `ApplicationEventMulticaster` except the type of listeners this multicaster can handle. Different from the aforementioned class, this interface is used for broadcasting life cycle events of application contexts started inside an OSGi environment, to outside entities. This normally implies that the entities as well as the multicaster are not managed by the application context triggering the event (so that a destruction event can be properly propagated).
