     * {@linkplain error.NoSuchElementError NoSuchElementError}.

     * The search criteria for an element may be defined using one of the static
     * factories on the {@link by.By} class, or as a short-hand
     * {@link ./by.ByHash} object. For example, the following two statements
     * are equivalent:
     *
     *     var e1 = shadowroot.findElement(By.id('foo'));
     *     var e2 = shadowroot.findElement({id:'foo'});

     * You may also provide a custom locator function, which takes as input this
     * instance and returns a {@link WebElement}, or a promise that will resolve
     * to a WebElement. If the returned promise resolves to an array of
     * WebElements, WebDriver will use the first element. For example, to find the
     * first visible link on a page, you could write:
     *
     *     var link = element.findElement(firstVisibleLink);
     *
     *     function firstVisibleLink(shadowRoot) {
     *       var links = shadowRoot.findElements(By.tagName('a'));
     *       return promise.filter(links, function(link) {
     *         return link.isDisplayed();
     *       });
     *     }
     *
     * @param {!(by.By|Function)} locator The locator strategy to use when
     *     searching for the element.
     * @return {!WebElementPromise} A WebElement that can be used to issue
     *     commands against the located element. If the element is not found, the
     *     element will be invalidated and all scheduled commands aborted.
