| -/**
|
| - * ChoiceFormat converts between ranges of numeric values
|
| - * and string names for those ranges. A <code>ChoiceFormat</code> splits
|
| - * the real number line <code>-Inf</code> to <code>+Inf</code> into two
|
| - * or more contiguous ranges. Each range is mapped to a
|
| - * string. <code>ChoiceFormat</code> is generally used in a
|
| - * <code>MessageFormat</code> for displaying grammatically correct
|
| - * plurals such as "There are 2 files."</p>
|
| - *
|
| - * <p>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 make up the
|
| - * <code>ChoiceFormat</code>.</p>
|
| - *
|
| - * <p><strong>Patterns</strong></p>
|
| - *
|
| - * <p>In most cases, the preferred way to define a
|
| - * <code>ChoiceFormat</code> is with a pattern. Here is an example of a
|
| - * <code>ChoiceFormat</code> pattern:</p>
|
| - *
|
| - * \htmlonly<pre> 0≤are no files|1≤is one file|1<are many files</pre>\endhtmlonly
|
| - *
|
| - * <p>or equivalently,</p>
|
| - *
|
| - * \htmlonly<pre> 0#are no files|1#is one file|1<are many files</pre>\endhtmlonly
|
| - *
|
| - * <p>The pattern consists of a number or <em>range specifiers</em>
|
| - * separated by vertical bars '|' (U+007C). There is no
|
| - * vertical bar after the last range. Each range specifier is of the
|
| - * form:</p>
|
| - *
|
| - * \htmlonly<blockquote><em>Number Separator String</em></blockquote>\endhtmlonly
|
| - *
|
| - * <p><em>Number</em> is a floating point number that can be parsed by a
|
| - * default <code>NumberFormat</code> for the US locale. It gives the
|
| - * lower limit of this range. The lower limit is either inclusive or
|
| - * exclusive, depending on the <em>separator</em>. The upper limit is
|
| - * given by the lower limit of the next range. The Unicode infinity
|
| - * sign \htmlonly∞ \endhtmlonly (U+221E) is recognized for positive infinity. It may be preceded by
|
| - * '-' (U+002D) to indicate negative infinity.</p>
|
| - *
|
| - * <p><em>String</em> is the format string for this range, with special
|
| - * characters enclosed in single quotes (<code>'The #
|
| - * sign'</code>). Single quotes themselves are indicated by two single
|
| - * quotes in a row (<code>'o''clock'</code>).</p>
|
| - *
|
| - * <p><em>Separator</em> is one of the following single characters:
|
| - *
|
| - * <ul>
|
| - * <li>\htmlonly'≤' \endhtmlonly (U+2264) or '#' (U+0023)
|
| - * indicates that the lower limit given by <em>Number</em> is
|
| - * inclusive. (The two characters are equivalent to ChoiceFormat.)
|
| - * This means that the limit value <em>Number</em> belongs to this
|
| - * range. Another way of saying this is that the corresponding
|
| - * closure is <code>FALSE</code>.</li>
|
| - *
|
| - * <li>'<' (U+003C) indicates that the lower limit given by
|
| - * <em>Number</em> is exclusive. This means that the value
|
| - * <em>Number</em> belongs to the prior range.</li> Another way of
|
| - * saying this is that the corresponding closure is
|
| - * <code>TRUE</code>.
|
| - * </ul>
|
| - *
|
| - * <p>See below for more information about closures.</p>
|
| - *
|
| - * <p><strong>Arrays</strong></p>
|
| - *
|
| - * <p>A <code>ChoiceFormat</code> defining <code>n</code> intervals
|
| - * (<code>n</code> >= 2) is specified by three arrays of
|
| - * <code>n</code> items:
|
| - *
|
| - * <ul>
|
| - * <li><code>double limits[]</code> gives the start of each
|
| - * interval. This must be a non-decreasing list of values, none of
|
| - * which may be <code>NaN</code>.</li>
|
| - * <li><code>UBool closures[]</code> determines whether each limit
|
| - * value is contained in the interval below it or in the interval
|
| - * above it. If <code>closures[i]</code> is <code>FALSE</code>, then
|
| - * <code>limits[i]</code> is a member of interval
|
| - * <code>i</code>. Otherwise it is a member of interval
|
| - * <code>i+1</code>. If no closures array is specified, this is
|
| - * equivalent to having all closures be <code>FALSE</code>. Closures
|
| - * allow one to specify half-open, open, or closed intervals.</li>
|
| - * <li><code>UnicodeString formats[]</code> gives the string label
|
| - * associated with each interval.</li>
|
| - * </ul>
|
| - *
|
| - * <p><strong>Formatting and Parsing</strong></p>
|
| - *
|
| - * <p>During formatting, a number is converted to a
|
| - * string. <code>ChoiceFormat</code> accomplishes this by mapping the
|
| - * number to an interval using the following rule. Given a number
|
| - * <code>X</code> and and index value <code>j</code> in the range
|
| - * <code>0..n-1</code>, where <code>n</code> is the number of ranges:</p>
|
| - *
|
| - * \htmlonly<blockquote>\endhtmlonly<code>X</code> matches <code>j</code> if and only if
|
| - * <code>limit[j] <= X < limit[j+1]</code>
|
| - * \htmlonly</blockquote>\endhtmlonly
|
| - *
|
| - * <p>(This assumes that all closures are <code>FALSE</code>. If some
|
| - * closures are <code>TRUE</code> then the relations must be changed to
|
| - * <code><=</code> or <code><</code> as appropriate.) If there is
|
| - * no match, then either the first or last index is used, depending on
|
| - * whether the number is too low or too high. Once a number is mapped to
|
| - * an interval <code>j</code>, the string <code>formats[j]</code> is
|
| - * output.</p>
|
| - *
|
| - * <p>During parsing, a string is converted to a
|
| - * number. <code>ChoiceFormat</code> finds the element
|
| - * <code>formats[j]</code> equal to the string, and returns
|
| - * <code>limits[j]</code> as the parsed value.</p>
|
| - *
|
| - * <p><strong>Notes</strong></p>
|
| - *
|
| - * <p>The first limit value does not define a range boundary. For
|
| - * example, in the pattern \htmlonly"<code>1.0#a|2.0#b</code>"\endhtmlonly, the
|
| - * intervals are [-Inf, 2.0) and [2.0, +Inf]. It appears that the first
|
| - * interval should be [1.0, 2.0). However, since all values that are too
|
| - * small are mapped to range zero, the first interval is effectively
|
| - * [-Inf, 2.0). However, the first limit value <em>is</em> used during
|
| - * formatting. In this example, <code>parse("a")</code> returns
|
| - * 1.0.</p>
|
| - *
|
| - * <p>There are no gaps between intervals and the entire number line is
|
| - * covered. A <code>ChoiceFormat</code> maps <em>all</em> possible
|
| - * double values to a finite set of intervals.</p>
|
| - *
|
| - * <p>The non-number <code>NaN</code> is mapped to interval zero during
|
| - * formatting.</p>
|
| - *
|
| - * <p><strong>Examples</strong></p>
|
| - *
|
| - * <p>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>.</p>
|
| - *
|
| - * <pre> {1,2,3,4,5,6,7},
|
| - * {"Sun","Mon","Tue","Wed","Thur","Fri","Sat"}</pre>
|
| - *
|
| - * <p>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 < 1.0, x = 1.0, and x > 1.0.</p>
|
| - *
|
| - * <pre> {0, 1, 1},
|
| - * {FALSE, FALSE, TRUE},
|
| - * {"no files", "one file", "many files"}</pre>
|
| - *
|
| - * <p>Here is a simple example that shows formatting and parsing: </p>
|
| - *
|
| - * \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
|
| - *
|
| - * <p>Here is a more complex example using a <code>ChoiceFormat</code>
|
| - * constructed from a pattern together with a
|
| - * <code>MessageFormat</code>.</p>
|
| - *
|
| - * \code
|
| - * #include <unicode/choicfmt.h>
|
| - * #include <unicode/msgfmt.h>
|
| - * #include <unicode/unistr.h>
|
| - * #include <iostream.h>
|
| - *
|
| - * int main(int argc, char *argv[]) {
|
| - * UErrorCode status = U_ZERO_ERROR;
|
| - * double filelimits[] = {0,1,2};
|
| - * UnicodeString filepart[] =
|
| - * {"are no files","is one file","are {0} files"};
|
| - * ChoiceFormat* fileform = new ChoiceFormat(filelimits, filepart, 3 );
|
| - * Format* testFormats[] =
|
| - * {fileform, NULL, NumberFormat::createInstance(status)};
|
| - * MessageFormat pattform("There {0} on {1}", status );
|
| - * pattform.adoptFormats(testFormats, 3);
|
| - * Formattable testArgs[] = {0L, "Disk A"};
|
| - * FieldPosition fp(0);
|
| - * UnicodeString str;
|
| - * char buf[256];
|
| - * for (int32_t i = 0; i < 4; ++i) {
|
| - * Formattable fInt(i);
|
| - * testArgs[0] = fInt;
|
| - * pattform.format(testArgs, 2, str, fp, status );
|
| - * str.extract(0, str.length(), buf, "");
|
| - * str.truncate(0);
|
| - * cout << "Output for i=" << i << " : " << buf << endl;
|
| - * }
|
| - * cout << endl;
|
| - * return 0;
|
| - * }
|
| - * \endcode
|
| - *
|
| - * <p><em>User subclasses are not supported.</em> While clients may write
