Example 17 with BundleListener

use of org.osgi.framework.BundleListener in project eclipse.platform.runtime by eclipse.

the class OSGiObjectSupplier method track.

private void track(final Bundle bundle, final IRequestor requestor) {
    // A _synchronous_ BundleListener asserts that the BC is un-injected,
    // _before_ it becomes invalid (state-wise).
    BundleListener listener = new SynchronousBundleListener() {

        @Override
        public void bundleChanged(BundleEvent event) {
            if (event.getBundle().equals(bundle)) {

                    requestor.resolveArguments(false);
                    requestor.execute();
                }
