Namespace

Code

protected function bubble(GeneratedUrl $generated_url, array $options = []) {
    // Bubbling metadata makes sense only if the code is executed inside a
    // render context. All code running outside controllers has no render
    // context by default, so URLs used there are not supposed to affect the
    // response cacheability.
    if ($this->renderer
        ->hasRenderContext()) {
        $build = [];
        $generated_url->applyTo($build);
