How to sync upstream?

[srid3]

private void getOrCreateForkedRepo(GitHub github, GHRepository originalRepo) throws IOException, InterruptedException {
        GHRepository forkedRepo = github.getMyself().getRepository(originalRepo.getName());
        if (forkedRepo == null) {
            originalRepo.fork();
        } else {
            // Sync with upstream
        }
    }

Is there a direct api call to sync with upstream?
