Method Detail

start

public void start(org.osgi.framework.BundleContext context)

Called upon starting of the bundle. Constructs and registers the EventAdmin service with the framework. Note that the properties of the service are requested from the context in this method hence, the bundle has to be restarted in order to take changed properties into account.

Specified by:

start in interface org.osgi.framework.BundleActivator

Parameters:

context - The bundle context passed by the framework

See Also:

BundleActivator.start(org.osgi.framework.BundleContext)

stop

public void stop(org.osgi.framework.BundleContext context)

Called upon stopping the bundle. This will block until all pending events are delivered. An IllegalStateException will be thrown on new events starting with the begin of this method. However, it might take some time until we settle down which is somewhat cumbersome given that the spec asks for return in a timely manner.

Specified by:

stop in interface org.osgi.framework.BundleActivator

Parameters:

context - The bundle context passed by the framework

BundleActivator.stop(org.osgi.framework.BundleContext)
