Examples with Listener aQute.bnd.service.repository.ResourceRepository.Listener used on opensource projects

Example 1 with Listener

use of aQute.bnd.service.repository.ResourceRepository.Listener in project bnd by bndtools.

the class ResourceRepoTest method testMultipleDownloads.

public void testMultipleDownloads() throws Exception {
    final Semaphore s = new Semaphore(0);
    final AtomicInteger downloads = new AtomicInteger();
    ResourceDescriptor rd = create("jar/osgi.jar");
    repoImpl.add("x", rd);
    final Semaphore done = new Semaphore(0);
    DownloadListener l = new DownloadListener() {

        @Override
        public void success(File file) throws Exception {
            done.release();
        }

        @Override
        public void failure(File file, String reason) throws Exception {
            System.out.println("failure! " + file + " " + reason);
        }

        @Override
        public boolean progress(File file, int percentage) throws Exception {
            return false;
        }
    };
    repoImpl.addListener(new Listener() {

        @Override
        public void events(ResourceRepositoryEvent... events) throws Exception {
            for (ResourceRepositoryEvent event : events) {
                if (event.type == TYPE.START_DOWNLOAD) {
                    System.out.println("trying to acquire s");
                    s.acquire();
                    System.out.println("got it");
                    downloads.incrementAndGet();
                }
            }
