Method Details

create

public static LiteralLabel create(String lex,
 RDFDatatype dtype)

Create a literal with a dtype.

createLiteralLabel

public static LiteralLabel createLiteralLabel(String lex,
 String lang,
 RDFDatatype dtype)
                                       throws DatatypeFormatException

Using create(String, String) or create(String, RDFDatatype) where possible is preferred.

Throws:

DatatypeFormatException

create

public static LiteralLabel create(String lex,
 String lang)

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

Parameters:

lex - the lexical form of the literal

lang - the optional language tag, only relevant for plain literals

createByValue

public static LiteralLabel createByValue(Object value,
 String lang,
 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

lang - the optional language tag, only relevant for plain literals

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

Throws:

DatatypeFormatException

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 plain string becomes an xsd:string.

Parameters:

value - the literal value to encapsulate

create

public static LiteralLabel create(String s,
 String lang,
 boolean xml)

Creates either a plain literal or an XMLLiteral.

Parameters:

xml - If true then s is exclusive canonical XML of type rdf:XMLLiteral, and no checking will be invoked.
