Cardinality example
This localized strings example uses complete, page-local CLDR minimal-pair patterns to demonstrate every Cardinality category defined for the locale. Minimal-pair text contrasts grammatical forms; it is language-reference data, not reusable application copy.
Source: Unicode CLDR 48.2 ur locale data.
Sample localized strings file
{ "Cardinality.MinimalPair": { "commentary": "Demonstrates every CLDR cardinal category defined for this locale.", "translation": "{{cardinalityExample}}", "placeholders": { "cardinalityExample": { "value": "cardinalityValue", "translations": { "CARDINALITY_ONE": "{{formattedCardinalityValue}} گھنٹہ", "CARDINALITY_OTHER": "{{formattedCardinalityValue}} گھنٹے" } } } } }
Usage and expected results
The Java code passes each raw number for cardinality selection and formats its display value separately with NumberFormat. For this right-to-left locale, Lokalized's default BidiIsolation.RTL_LOCALES wraps caller-supplied formatted values with U+2068 FIRST STRONG ISOLATE and U+2069 POP DIRECTIONAL ISOLATE; the expected expressions below show those escapes.
Locale locale = Locale.forLanguageTag("ur"); Strings strings = Strings.withFallbackLocale(locale) .localizedStringSupplier(() -> LocalizedStringLoader.loadFromFilesystem(Paths.get("strings"))) .localeSupplier((matcher) -> matcher.bestMatchFor(locale)) .build(); NumberFormat numberFormat = NumberFormat.getNumberInstance(locale); // Raw numbers select language forms; NumberFormat produces the display values // CARDINALITY_ONE Number oneCardinalityValue = 1; String oneFormattedCardinalityValue = numberFormat.format(oneCardinalityValue); assertEquals(Cardinality.ONE, Cardinality.forNumber(oneCardinalityValue, locale)); // Expected: <FSI>1<PDI> گھنٹہ // U+2068 FIRST STRONG ISOLATE begins bidirectional isolation around a caller-supplied value in right-to-left text // U+2069 POP DIRECTIONAL ISOLATE ends bidirectional isolation around a caller-supplied value in right-to-left text assertEquals("\u2068" + oneFormattedCardinalityValue + "\u2069 گھنٹہ", strings.get( "Cardinality.MinimalPair", Map.of( "cardinalityValue", oneCardinalityValue, "formattedCardinalityValue", oneFormattedCardinalityValue ) )); // CARDINALITY_OTHER Number otherCardinalityValue = 0; String otherFormattedCardinalityValue = numberFormat.format(otherCardinalityValue); assertEquals(Cardinality.OTHER, Cardinality.forNumber(otherCardinalityValue, locale)); // Expected: <FSI>0<PDI> گھنٹے assertEquals("\u2068" + otherFormattedCardinalityValue + "\u2069 گھنٹے", strings.get( "Cardinality.MinimalPair", Map.of( "cardinalityValue", otherCardinalityValue, "formattedCardinalityValue", otherFormattedCardinalityValue ) ));
Cardinality Ranges
These are CLDR's explicit range mappings. For any start/end pair not listed, Cardinality.forRange(...) falls back to the ending cardinality.
-
CARDINALITY_ONE - CARDINALITY_OTHER
Matches
CARDINALITY_OTHER -
CARDINALITY_OTHER - CARDINALITY_ONE
Matches
CARDINALITY_OTHER -
CARDINALITY_OTHER - CARDINALITY_OTHER
Matches
CARDINALITY_OTHER
Ordinalities
All ordinal numbers use ORDINALITY_OTHER; no value selects a different form.
Example: دایاں موڑ نمبر 2 مڑیں۔.
