Examples of org.osgi.framework.BundleActivator

org.osgi.framework.BundleActivator
Called when a bundle is started or stopped

        // CONCURRENCY NOTE:
        // This method is called indirectly from startBundle() (via _startBundle()),
        // which has the bundle lock, so there is no need to do any locking here.


        // Get the activator class from the header map.
        BundleActivator activator = null;
        Map headerMap = ((BundleRevisionImpl) impl.adapt(BundleRevision.class)).getHeaders();
        String className = (String) headerMap.get(Constants.BUNDLE_ACTIVATOR);
        // Try to instantiate activator class if present.
        if (className != null)
