Modifier and Type	Method	Description

static LiteralLabel	create(java.lang.String lex, RDFDatatype dtype)	Create a literal with a dtype.
static LiteralLabel	createByValue(java.lang.Object value, java.lang.String lang, RDFDatatype dtype)	Build a typed literal label from its value form.
static LiteralLabel	createLiteralLabel(java.lang.String lex, java.lang.String lang, RDFDatatype dtype)	Using create(String, String) or create(String, RDFDatatype) where possible is preferred.
static LiteralLabel	createTypedLiteral(java.lang.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.

Method Detail

create

public static LiteralLabel create(java.lang.String lex,
                                  RDFDatatype dtype)

Create a literal with a dtype.

createLiteralLabel

public static LiteralLabel createLiteralLabel(java.lang.String lex,
                                              java.lang.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(java.lang.String lex,
                                  java.lang.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(java.lang.Object value,
                                         java.lang.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(java.lang.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(java.lang.String s,
                                  java.lang.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.
