示例1: checkSelect
void PluralRulesTest::checkSelect(const LocalPointer<PluralRules> &rules, UErrorCode &status,
int32_t line, const char *keyword, ...) {
// The varargs parameters are a const char* strings, each being a decimal number.
// The formatting of the numbers as strings is significant, e.g.
// the difference between "2" and "2.0" can affect which rule matches (which keyword is selected).
// Note: rules parameter is a LocalPointer reference rather than a PluralRules * to avoid having
// to write getAlias() at every (numerous) call site.
if (U_FAILURE(status)) {
errln("file %s, line %d, ICU error status: %s.", __FILE__, line, u_errorName(status));
status = U_ZERO_ERROR;
return;
}
if (rules == NULL) {
errln("file %s, line %d: rules pointer is NULL", __FILE__, line);
return;
}
va_list ap;
va_start(ap, keyword);
for (;;) {
const char *num = va_arg(ap, const char *);
if (strcmp(num, END_MARK) == 0) {
break;
}
// DigitList is a convenient way to parse the decimal number string and get a double.
DigitList dl;
dl.set(StringPiece(num), status);
if (U_FAILURE(status)) {
errln("file %s, line %d, ICU error status: %s.", __FILE__, line, u_errorName(status));

const char *decimalPoint = strchr(num, '.');
int fractionDigitCount = decimalPoint == NULL ? 0 : (num + strlen(num) - 1) - decimalPoint;
int fractionDigits = fractionDigitCount == 0 ? 0 : atoi(decimalPoint + 1);
FixedDecimal ni(numDbl, fractionDigitCount, fractionDigits);
UnicodeString actualKeyword = rules->select(ni);
