## Advanced description from docstring { #advanced-description-from-docstring }

You can limit the lines used from the docstring of a *path operation function* for OpenAPI.

Adding an `\f` (an escaped "form feed" character) causes **FastAPI** to truncate the output used for OpenAPI at this point.

It won't show up in the documentation, but other tools (such as Sphinx) will be able to use the rest.

            protected PathMappingHelper getPathMappingHelper() {
                return new PathMappingHelper();
            }
        };
        fessXpathTransformer.init();
        fessXpathTransformer.convertUrlMap.put("feed:", "http:");

        List<RequestData> urlList = new ArrayList<>();

        urlList = fessXpathTransformer.convertChildUrlList(urlList);
        assertEquals(0, urlList.size());

        urlList.clear();

 *       {@code Number}, and primitive varargs are supported.
 *   <li>Or, to avoid storing up all the data first, create a {@link StatsAccumulator} instance,
 *       feed values to it as you get them, then call {@link StatsAccumulator#snapshot}.
 * </ul>
 *
 * <p>Static convenience methods called {@code meanOf} are also provided for users who wish to
 * calculate <i>only</i> the mean.
 *

        (command `print_source` / `ps`)
    *   New navigation bar in Curses-based UI
    *   NodeStepper (command `invoke_stepper`) now uses intermediate tensor
        dumps. It also uses `TensorHandles` as direct feeds during successive
        `cont` calls for improved performance and reduced memory consumption.
*   Initial release of installation guides for Java, C, and Go.
*   Added Text Dashboard to TensorBoard.
