org.osgi.service.blueprint.container.BlueprintEvent

A Blueprint Event.

{@code BlueprintEvent} objects are delivered to all registered{@link BlueprintListener} services. Blueprint Events must be asynchronouslydelivered in chronological order with respect to each listener.

In addition, after a Blueprint Listener is registered, the Blueprint extender will synchronously send to this Blueprint Listener the last Blueprint Event for each ready Blueprint bundle managed by this extender. This replay of Blueprint Events is designed so that the new Blueprint Listener can be informed of the state of each Blueprint bundle. Blueprint Events sent during this replay will have the {@link #isReplay()} flag set.The Blueprint extender must ensure that this replay phase does not interfere with new Blueprint Events so that the chronological order of all Blueprint Events received by the Blueprint Listener is preserved. If the last Blueprint Event for a given Blueprint bundle is {@link #DESTROYED}, the extender must not send it during this replay phase.

A type code is used to identify the type of event. The following event types are defined:

{@link #CREATING}
{@link #CREATED}
{@link #DESTROYING}
{@link #DESTROYED}
{@link #FAILURE}
{@link #GRACE_PERIOD}
{@link #WAITING}

In addition to calling the registered {@link BlueprintListener} services, theBlueprint extender must also send those events to the Event Admin service, if it is available. @see BlueprintListener @see EventConstants @Immutable @author $Id: 6155890329cf5bb2593958ad07bbb6ff9b161bc5 $
