LiteralLabelFactory

public LiteralLabelFactory()

Method Details

createString

public static LiteralLabel createString(String lex)

Create a string literal

createLang

public static LiteralLabel createLang(String lex,
 String lang)

Build a literal label from its lexical form and language tag.

Parameters:

lex - the lexical form of the literal

lang - the optional language tag

createDirLang

public static LiteralLabel createDirLang(String lex,
 String lang,
 TextDirection textDir)

Build a literal label from its lexical form,language tag and base direction

Parameters:

lex - the lexical form of the literal

lang - the optional language tag

textDir - the optional base direction (lang required)

create

public static LiteralLabel create(String lex,
 RDFDatatype dtype)

Create a literal with a dtype.

createLiteralLabel

public static LiteralLabel createLiteralLabel(String lex,
 String lang,
 TextDirection textDir,
 RDFDatatype dtype)

createByValue

public static LiteralLabel createByValue(Object value)
                                  throws DatatypeFormatException

Build a typed literal label from its value form. If the value is a string we assume this is intended to be a lexical form after all.

Parameters:

value - the value of the literal

Throws:

DatatypeFormatException

createByValue

public static LiteralLabel createByValue(Object value,
 RDFDatatype dtype)
                                  throws DatatypeFormatException

Build a typed literal label from its value form. If the value is a string we assume this is intended to be a lexical form after all.

Parameters:

value - the value of the literal

dtype - the type of the literal, null for old style "plain" literals (which become xsd:string in RDF 1.1)

Throws:

DatatypeFormatException

createIncludingValue

public static LiteralLabel createIncludingValue(String lex,
 Object value,
 RDFDatatype dtype)

Create a typed literal for which both the lexical form and the value form are already available. Use with care!

Parameters:

lex - the lexical form of the literal (assumed to be well-formed for the given datatype)

value - the value of the literal (assumed to be the value obtained when applying the lexical-to-value mapping of the the given datatype to the given lexical form)

dtype - the datatype of the literal

createTypedLiteral

public static LiteralLabel createTypedLiteral(Object value)

Build a typed literal label from its value form using whatever datatype is currently registered as the default representation for this java class. No language tag is supplied. A Java string becomes an xsd:string.

Parameters:

value - the literal value to encapsulate
