public class LocaleMapper

extends Object

LocaleMapper does mappings between Oracle locale elements and equivalent locale elements in other vendors and standards. This class contains the same mapping data as the C NLSRTL library and package oracle.gss.util.

The locale mappings are available for Oracle and Java locales. The character set encoding mappings are available for Oracle, Java, and IANA.

getAvailableIANACharacterSets

public static String[] getAvailableIANACharacterSets()

Returns an array of all IANA character set names that have corresponding Oracle Character sets

Returns:

an array of String containing the list of IANA names.

getAvailableOraCharacterSets

public static String[] getAvailableOraCharacterSets()

Returns an array of all Oracle character set names that have corresponding IANA character sets

Returns:

an array of String containing the list of Oracle names.

getIANACharacterSet

public static String getIANACharacterSet(int from,
String charset)

Returns the IANA character set that is equivalent to the Oracle or Java Character set passed in

Parameters:

from - can be ORACLE or JAVA

charset - character set name with which we want to find an equivalent IANA character set

Returns:

IANA character set name, null if not found

getJavaCharacterSet

public static String getJavaCharacterSet(int from,
String charset)

Returns the Java character set that is equivalent to the Oracle or IANA Character set passed in

Parameters:

from - can be ORACLE or IANA

charset - character set name with which we want to find an equivalent Java character set

Returns:

Java character set name, null if not found

getOraCharacterSet

public static String getOraCharacterSet(int from,
String charset)

Returns the Oracle character set that is equivalent to the Java Character set passed in

Parameters:

from - can be IANA or JAVA

charset - character set name with which we want to find an equivalent Oracle character set

Returns:

Oracle character set name, null if not found

getJavaLocale

public static Locale getJavaLocale(String oraLanguage,
String oraTerritory)

Returns a Java Locale instance that is equivalent to the oracle locale specified by the passed in Oracle language and territory

Parameters:

oraLanguage - Oracle language

oraTerritory - Oracle territory

Returns:

Java Locale instance, defaults to American_America

getOraLanguageFromShortName

public static String getOraLanguageFromShortName(String oraShortName)

Returns the Oracle language name from the Oracle short language name

Parameters:

oraShortName - Oracle short language name

Returns:

Oracle language name

getOraLanguage

public static String getOraLanguage(Locale locale)

Returns the Oracle language name based on given Java Locale

Parameters:

locale - Java locale instance

Returns:

Oracle language name associated with the given locale, or null no corresponding Oracle language is found.

getOraTerritory

public static String getOraTerritory(Locale locale)

Returns the Oracle territory name given a Java Locale

Parameters:

locale - Java locale instance

Returns:

Oracle territory name associated with the given locale

getIANACharSetFromLocale

public static String[] getIANACharSetFromLocale(int context,
Locale locale)

Returns commonly used IANA Character set based on the given context and locale. For example, an email application may need to use a different character set than a web application

Parameters:

context - can be EMAIL_WINDOWS, EMAIL_UNIX, WINDOWS, UNIX

locale - Java Locale

Returns:

Oracle territory name associated with the given locale

getIANACharSetFromOraLang

public static String[] getIANACharSetFromOraLang(int context,
String oraLanguage)

Returns commonly used IANA Character set based on the given context and Oracle language. For example, an email application may need to use a different character set than a web application

Parameters:

context - can be EMAIL_WINDOWS, EMAIL_UNIX, WINDOWS, UNIX

oraLanguage - Oracle language

Returns:

Oracle territory name associated with the given locale

getOraCharSetFromOraLang

public static String[] getOraCharSetFromOraLang(int context,
String oraLanguage)

Returns commonly used Oracle Character set based on the given context and Oracle language. For example, an email application may need to use a different character set than a web application

Parameters:

context - can be EMAIL_WINDOWS, EMAIL_UNIX, WINDOWS, UNIX

oraLanguage - Oracle language

Returns:

Oracle territory name associated with the given locale

getOraLangFromJavaLang

public static String getOraLangFromJavaLang(String lang)

Returns Oracle language name given ISO 639 two letter code

Due to the limitation of ISO 639 two letter code, Simplified Chinese and Tradtional Chinese cannot be distinguished. In fact, if zh is given, this method returns Simplified Chinese only; it never returns Traditional Chinese.
Use getOraLanguage(java.util.Locale) if those two Chinese languages need to be distinguished.

Parameters:

lang - ISO 639 two letter code

Returns:

Oracle language name

getJavaLangFromOraLang

public static String getJavaLangFromOraLang(String lang)

Returns ISO 639 two letter code given Oracle language name

Due to the same reason discussed in getOraLangFromJavaLang(java.lang.String), if either Simplified Chinese and Traditional Chinese is specified, this method always returns zh. It means it loses the information.
Use getJavaLocale(java.lang.String, java.lang.String) instead.

Parameters:

lang - Oracle language name

Returns:

ISO 639 two letter code

getOraTerrFromJavaTerr

public static String getOraTerrFromJavaTerr(String terr)

Returns Oracle territory name given ISO 3166 two letter code

Parameters:

terr - ISO 3166 two letter code

Returns:

Oracle territory name

getJavaTerrFromOraTerr

public static String getJavaTerrFromOraTerr(String terr)

Returns ISO 3166 two letter code given Oracle territory name

Parameters:

terr - Oracle territory name

Returns:

ISO 3166 two letter code
