Method Detail

start

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

Called when this bundle is started so the Framework can perform the bundle-specific activities necessary to start this bundle. This method can be used to register services or to allocate any resources that this bundle needs.

This method must complete and return to its caller in a timely manner.

Specified by:

start in interface org.osgi.framework.BundleActivator

Parameters:

context - The execution context of the bundle being started.

Throws:

Exception - If this method throws an exception, this bundle is marked as stopped and the Framework will remove this bundle's listeners, unregister all services registered by this bundle, and release all services used by this bundle.

stop

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

Called when this bundle is stopped so the Framework can perform the bundle-specific activities necessary to stop the bundle. In general, this method should undo the work that the BundleActivator.start method started. There should be no active threads that were started by this bundle when this bundle returns. A stopped bundle must not call any Framework objects.

This method must complete and return to its caller in a timely manner.

Specified by:

stop in interface org.osgi.framework.BundleActivator

Parameters:

context - The execution context of the bundle being stopped.

Throws:

Exception - If this method throws an exception, the bundle is still marked as stopped, and the Framework will remove the bundle's listeners, unregister all services registered by the bundle, and release all services used by the bundle.
