class MessageFormat;

/**
 * ChoiceFormat converts between ranges of numeric values and strings for those ranges.
 * The strings must conform to the MessageFormat pattern syntax.
 *
 * <code>ChoiceFormat</code> is probably not what you need.
 * Please use <code>MessageFormat</code>
 * with <code>plural</code> arguments for proper plural selection,
 * and <code>select</code> arguments for simple selection among a fixed set of choices!
 *
 * A <code>ChoiceFormat</code> splits
 * the real number line \htmlonly<code>-&#x221E;</code> to
 * <code>+&#x221E;</code>\endhtmlonly into two
 * or more contiguous ranges. Each range is mapped to a
 * string.
 *
 * <code>ChoiceFormat</code> was originally intended
 * for displaying grammatically correct
 * plurals such as &quot;There is one file.&quot; vs. &quot;There are 2 files.&quot;
 * However, plural rules for many languages
 * are too complex for the capabilities of ChoiceFormat,
 * and its requirement of specifying the precise rules for each message
 * is unmanageable for translators.
 *
 * There are two methods of defining a <code>ChoiceFormat</code>; both
 * are equivalent. The first is by using a string pattern. This is the
 * preferred method in most cases. The second method is through direct
 * specification of the arrays that logically make up the
 * <code>ChoiceFormat</code>.
 *
 * Note: Typically, choice formatting is done (if done at all) via <code>MessageFormat</code>
 * with a <code>choice</code> argument type,
 * rather than using a stand-alone <code>ChoiceFormat</code>.
 *
 * <h5>Patterns and Their Interpretation</h5>
 *
 * The pattern string defines the range boundaries and the strings for each number range.
 * Syntax:
 * <pre>
 * choiceStyle = number separator message ('|' number separator message)*
 * number = normal_number | ['-'] \htmlonly&#x221E;\endhtmlonly (U+221E, infinity)
 * normal_number = double value (unlocalized ASCII string)
 * separator = less_than | less_than_or_equal
 * less_than = '<'
 * less_than_or_equal = '#' | \htmlonly&#x2264;\endhtmlonly (U+2264)
 * message: see {@link MessageFormat}
 * </pre>
 * Pattern_White_Space between syntax elements is ignored, except
 * around each range's sub-message.
 *
 * Each numeric sub-range extends from the current range's number
 * to the next range's number.
 * The number itself is included in its range if a <code>less_than_or_equal</code> sign is used,
 * and excluded from its range (and instead included in the previous range)
 * if a <code>less_than</code> sign is used.
 *
 * When a <code>ChoiceFormat</code> is constructed from
 * arrays of numbers, closure flags and strings,
 * they are interpreted just like
 * the sequence of <code>(number separator string)</code> in an equivalent pattern string.
 * <code>closure[i]==true</code> corresponds to a <code>less_than</code> separator sign.
 * The equivalent pattern string will be constructed automatically.
 *
 * During formatting, a number is mapped to the first range
 * where the number is not greater than the range's upper limit.
 * That range's message string is returned. A NaN maps to the very first range.
 *
 * During parsing, a range is selected for the longest match of
 * any range's message. That range's number is returned, ignoring the separator/closure.
 * Only a simple string match is performed, without parsing of arguments that
 * might be specified in the message strings.
 *
 * Note that the first range's number is ignored in formatting
 * but may be returned from parsing.
 *
 * <h5>Examples</h5>
 *
 * Here is an example of two arrays that map the number
 * <code>1..7</code> to the English day of the week abbreviations
 * <code>Sun..Sat</code>. No closures array is given; this is the same as
 * specifying all closures to be <code>false</code>.
 *
 * <pre> {1,2,3,4,5,6,7},
 * {&quot;Sun&quot;,&quot;Mon&quot;,&quot;Tue&quot;,&quot;Wed&quot;,&quot;Thur&quot;,&quot;Fri&quot;,&quot;Sat&quot;}</pre>
 *
 * Here is an example that maps the ranges [-Inf, 1), [1, 1], and (1,
 * +Inf] to three strings. That is, the number line is split into three
 * ranges: x &lt; 1.0, x = 1.0, and x &gt; 1.0.
 * (The round parentheses in the notation above indicate an exclusive boundary,
 * like the turned bracket in European notation: [-Inf, 1) == [-Inf, 1[ )
 *
 * <pre> {0, 1, 1},
 * {false, false, true},
 * {&quot;no files&quot;, &quot;one file&quot;, &quot;many files&quot;}</pre>
 *
 * Here is an example that shows formatting and parsing: 
 *
 * \code
 * #include <unicode/choicfmt.h>
 * #include <unicode/unistr.h>
 * #include <iostream.h>
 *
 * int main(int argc, char *argv[]) {
 * double limits[] = {1,2,3,4,5,6,7};
 * UnicodeString monthNames[] = {
 * "Sun","Mon","Tue","Wed","Thu","Fri","Sat"};
 * ChoiceFormat fmt(limits, monthNames, 7);
 * UnicodeString str;
 * char buf[256];
 * for (double x = 1.0; x <= 8.0; x += 1.0) {
 * fmt.format(x, str);
 * str.extract(0, str.length(), buf, 256, "");
 * str.truncate(0);
 * cout << x << " -> "
 * << buf << endl;
 * }
 * cout << endl;
 * return 0;
 * }
 * \endcode
 *
 * User subclasses are not supported. While clients may write
 * subclasses, such code will not necessarily work and will not be
 * guaranteed to work stably from release to release.

 * intervals. The intervals are:
 *
 * 0: fChoiceLimits[0]..fChoiceLimits[1]
 * 1: fChoiceLimits[1]..fChoiceLimits[2]
 * ...
 * fCount-2: fChoiceLimits[fCount-2]..fChoiceLimits[fCount-1]
 * fCount-1: fChoiceLimits[fCount-1]..+Inf
 *
 * Interval 0 is special; during formatting (mapping numbers to
 * strings), it also contains all numbers less than
 * fChoiceLimits[0], as well as NaN values.
 *
 * Interval i maps to and from string fChoiceFormats[i]. When
 * parsing (mapping strings to numbers), then intervals map to
 * their lower limit, that is, interval i maps to fChoiceLimit[i].
 *
 * The intervals may be closed, half open, or open. This affects
 * formatting but does not affect parsing. Interval i is affected
 * by fClosures[i] and fClosures[i+1]. If fClosures[i]
 * is false, then the value fChoiceLimits[i] is in interval i.
 * That is, intervals i and i are:
 *
 * i-1: ... x < fChoiceLimits[i]
 * i: fChoiceLimits[i] <= x ...
 *
 * If fClosures[i] is true, then the value fChoiceLimits[i] is
 * in interval i-1. That is, intervals i-1 and i are:
 *
 * i-1: ... x <= fChoiceLimits[i]
 * i: fChoiceLimits[i] < x ...
 *
 * Because of the nature of interval 0, fClosures[0] has no
 * effect.
