Constructor Details

ICUCurrencyDisplayInfo

public ICUCurrencyDisplayInfo(ULocale locale,
 ICUResourceBundle rb,
 boolean fallback)

Method Details

getULocale

public ULocale getULocale()

Description copied from class: CurrencyDisplayNames

Returns the locale used to determine how to translate the currency names. This is not necessarily the same locale passed to CurrencyDisplayNames.getInstance(ULocale).

Specified by:

getULocale in class CurrencyDisplayNames

Returns:

the display locale

getName

public String getName(String isoCode)

Description copied from class: CurrencyDisplayNames

Returns the 'long name' for the currency with the provided ISO code. If there is no data for the ISO code, substitutes isoCode, or returns null if noSubstitute was set in the factory method.

Specified by:

getName in class CurrencyDisplayNames

Parameters:

isoCode - the three-letter ISO code

Returns:

the display name

getSymbol

public String getSymbol(String isoCode)

Description copied from class: CurrencyDisplayNames

Returns the symbol for the currency with the provided ISO code.

If there is no data for this symbol, substitutes isoCode, or returns null if noSubstitute was set in the factory method.

Specified by:

getSymbol in class CurrencyDisplayNames

Parameters:

isoCode - the three-letter ISO code.

Returns:

the symbol.

getNarrowSymbol

public String getNarrowSymbol(String isoCode)

Description copied from class: CurrencyDisplayNames

Returns the narrow symbol for the currency with the provided ISO code.

The narrow currency symbol is similar to the regular currency symbol, but it always takes the shortest form; for example, "$" instead of "US$" for USD in en-CA.

If there is no data for this symbol, substitutes the default symbol, or returns null if noSubstitute was set in the factory method.

Specified by:

getNarrowSymbol in class CurrencyDisplayNames

Parameters:

isoCode - the three-letter ISO code.

Returns:

the narrow symbol.

getFormalSymbol

public String getFormalSymbol(String isoCode)

Description copied from class: CurrencyDisplayNames

Returns the formal symbol for the currency with the provided ISO code.

The formal currency symbol is similar to the regular currency symbol, but it always takes the form used in formal settings such as banking; for example, "NT$" instead of "$" for TWD in zh-TW.

If there is no data for this symbol, substitutes the default symbol, or returns null if noSubstitute was set in the factory method.

Specified by:

getFormalSymbol in class CurrencyDisplayNames

Parameters:

isoCode - the three-letter ISO code.

Returns:

the formal symbol.

getVariantSymbol

public String getVariantSymbol(String isoCode)

Description copied from class: CurrencyDisplayNames

Returns the variant symbol for the currency with the provided ISO code.

The variant symbol for a currency is an alternative symbol that is not necessarily as widely used as the regular symbol.

If there is no data for variant symbol, substitutes the default symbol, or returns null if noSubstitute was set in the factory method.

Specified by:

getVariantSymbol in class CurrencyDisplayNames

Parameters:

isoCode - the three-letter ISO code.

Returns:

the variant symbol.

getPluralName

public String getPluralName(String isoCode,
 String pluralKey)

Description copied from class: CurrencyDisplayNames

Returns a 'plural name' for the currency with the provided ISO code corresponding to the pluralKey. If there is no data for the ISO code, substitutes isoCode or returns null. If there is data for the ISO code but no data for the plural key, substitutes the 'other' value (and failing that the isoCode) or returns null.

Specified by:

getPluralName in class CurrencyDisplayNames

Parameters:

isoCode - the three-letter ISO code

pluralKey - the plural key, for example "one", "other"

Returns:

the display name

• PluralRules

symbolMap

public Map<String,String> symbolMap()

Description copied from class: CurrencyDisplayNames

Returns a mapping from localized symbols and currency codes to currency codes. The returned map is unmodifiable.

Specified by:

symbolMap in class CurrencyDisplayNames

Returns:

the map

nameMap

public Map<String,String> nameMap()

Description copied from class: CurrencyDisplayNames

Returns a mapping from localized names (standard and plural) to currency codes. The returned map is unmodifiable.
