LoaderUtils { public static Index findIndex(String reference) { return Index.of(reference); } private  LoaderUtils(); static Index findIndex(String reference); static boolean parseBoolean(String str); static int parseInteger(String str); static double parseDouble(String str); static double parseDoublePercent(String str); static BigDecimal parseBigDecimal(String str); static BigDecimal parseBigDecimalPercent(String str); static LocalDate parseDate(String str, DateTimeFormatter... formatters); static LocalDate parseDate(String str); static YearMonth parseYearMonth(String str); static LocalTime parseTime(String str); static ZoneId parseZoneId(String str); static Period parsePeriod(String str); static Tenor parseTenor(String str); static Optional<Tenor> tryParseTenor(String str); static Frequency parseFrequency(String str); static Currency parseCurrency(String str); static Optional<Currency> tryParseCurrency(String str); static DayCount parseDayCount(String str); static BusinessDayConvention parseBusinessDayConvention(String str); static RollConvention parseRollConvention(String str); static BuySell parseBuySell(String str); static PayReceive parsePayReceive(String str); static PutCall parsePutCall(String str); static LongShort parseLongShort(String str); static final String DEFAULT_TRADE_SCHEME; static final String DEFAULT_POSITION_SCHEME; static final String DEFAULT_SECURITY_SCHEME; }### Answer:
@Test public void test_findIndex() { assertThat(LoaderUtils.findIndex("GBP-LIBOR-3M")).isEqualTo(IborIndices.GBP_LIBOR_3M); assertThat(LoaderUtils.findIndex("GBP-SONIA")).isEqualTo(OvernightIndices.GBP_SONIA); assertThat(LoaderUtils.findIndex("GB-RPI")).isEqualTo(PriceIndices.GB_RPI); assertThat(LoaderUtils.findIndex("GBP/USD-WM")).isEqualTo(FxIndices.GBP_USD_WM); assertThatIllegalArgumentException().isThrownBy(() -> LoaderUtils.findIndex("Rubbish")); }
