Method Details

createLanguageTag

public static org.apache.jena.langtag.LangTag createLanguageTag(String langTagStr)

Create a LangTag object, using the Jena system default implementation of the LangTag interface. The string must conform to the syntax defined in rules and syntax in RFC 5646

formatLanguageTag

public static String formatLanguageTag(String langTagStr)

Prepare the language tag - apply formatting normalization, and always return a string. If the input is invalid as a language tag, return the input as-is.

Throws:

JenaException - on an all blank string.

canonical

@Deprecated(forRemoval=true)
public static String canonical(String langTagStr)

Deprecated, for removal: This API element is subject to removal in a future version.

Use formatLanguageTag(String)

checkLanguageTag

public static boolean checkLanguageTag(String langTagStr)

Check a string is valid as a language tag. This function returns true or false and does not throw an exception.

checkLanguageTagBasicSyntax

public static boolean checkLanguageTagBasicSyntax(String langTagStr)

Check a language tag string meets the Turtle(etc) and SPARQL grammar rule for a language tag without initial text direction.

Passing this test does not guarantee the string is valid language tag. Use checkLanguageTag(String) for validity checking.

requireValidLanguageTag

public static void requireValidLanguageTag(String langTagStr)

Check a string is valid as a language tag. Throw a JenaException if it is not valid.

sameLanguageTagAs

public static boolean sameLanguageTagAs(String langTagStr1,
 String langTagStr2)

Is @code{langTagStr1} the same language tag as @code{langTagStr2}?
