示例1: BaseException

  load(template: ViewDefinition): Promise</*element*/ any> {
    if (isPresent(template.template)) {
      return PromiseWrapper.resolve(DOM.createTemplate(template.template));
    }
    var url = template.absUrl;
    if (isPresent(url)) {
      var promise = StringMapWrapper.get(this._htmlCache, url);

      if (isBlank(promise)) {
        // TODO(vicb): change error when TS gets fixed
        // https://github.com/angular/angular/issues/2280
        // throw new BaseException(`Failed to fetch url "${url}"`);
        promise = PromiseWrapper.then(this._xhr.get(url), html => {
          var template = DOM.createTemplate(html);
          return template;
        }, _ => PromiseWrapper.reject(new BaseException(`Failed to fetch url "${url}"`), null));

        StringMapWrapper.set(this._htmlCache, url, promise);
      }

      // (e.g. the compiler).

    }
