331 * Formats simple relative dates. There are two types of relative dates that

334 * <li>relative dates with a quantity e.g "in 5 days"</li>
335 * <li>relative dates without a quantity e.g "next Tuesday"</li>
336 * </ul>
337 * <p>
338 * This API is very basic and is intended to be a building block for more
339 * fancy APIs. The caller tells it exactly what to display in a locale
340 * independent way. While this class automatically provides the correct plural
341 * forms, the grammatical form is otherwise as neutral as possible. It is the
342 * caller's responsibility to handle cut-off logic such as deciding between
343 * displaying "in 7 days" or "in 1 week." This API supports relative dates
344 * involving one single unit. This API does not support relative dates
345 * involving compound units,
346 * e.g "in 5 days and 4 hours" nor does it support parsing.
347 * <p>
348 * This class is mostly thread safe and immutable with the following caveats:
349 * 1. The assignment operator violates Immutability. It must not be used
350 * concurrently with other operations.
351 * 2. Caller must not hold onto adopted pointers.
352 * <p>
353 * This class is not intended for public subclassing.
354 * <p>
355 * Here are some examples of use:
356 * <blockquote>
357 * <pre>
358 * UErrorCode status = U_ZERO_ERROR;
359 * UnicodeString appendTo;
360 * RelativeDateTimeFormatter fmt(status);
361 * // Appends "in 1 day"
362 * fmt.format(
363 * 1, UDAT_DIRECTION_NEXT, UDAT_RELATIVE_DAYS, appendTo, status);
364 * // Appends "in 3 days"
365 * fmt.format(
366 * 3, UDAT_DIRECTION_NEXT, UDAT_RELATIVE_DAYS, appendTo, status);
367 * // Appends "3.2 years ago"
368 * fmt.format(
369 * 3.2, UDAT_DIRECTION_LAST, UDAT_RELATIVE_YEARS, appendTo, status);
370 * // Appends "last Sunday"
371 * fmt.format(UDAT_DIRECTION_LAST, UDAT_ABSOLUTE_SUNDAY, appendTo, status);
372 * // Appends "this Sunday"
373 * fmt.format(UDAT_DIRECTION_THIS, UDAT_ABSOLUTE_SUNDAY, appendTo, status);
374 * // Appends "next Sunday"
375 * fmt.format(UDAT_DIRECTION_NEXT, UDAT_ABSOLUTE_SUNDAY, appendTo, status);
376 * // Appends "Sunday"
377 * fmt.format(UDAT_DIRECTION_PLAIN, UDAT_ABSOLUTE_SUNDAY, appendTo, status);
378 *
379 * // Appends "yesterday"
380 * fmt.format(UDAT_DIRECTION_LAST, UDAT_ABSOLUTE_DAY, appendTo, status);
381 * // Appends "today"
382 * fmt.format(UDAT_DIRECTION_THIS, UDAT_ABSOLUTE_DAY, appendTo, status);
383 * // Appends "tomorrow"
384 * fmt.format(UDAT_DIRECTION_NEXT, UDAT_ABSOLUTE_DAY, appendTo, status);

387 *
388 * </pre>
389 * </blockquote>
390 * <p>
