      @Deprecated public static Node createLiteral(LiteralLabel lit)
      Deprecated.
      Making nodes directly from LiteralLabel may be removed.
      Make a literal node with the specified literal value

    • createLiteral

      @Deprecated(forRemoval=true) public static Node createLiteral(String string)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Use createLiteralString(java.lang.String)

    • createLiteralString

      public static Node createLiteralString(String string)

    • createLiteral

      @Deprecated(forRemoval=true) public static Node createLiteral(String string, String lang)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Use createLiteralLang(String, String).
      Make a literal with specified language. The lexical form must not be null.
      Parameters:
      string - the lexical form of the literal
      lang - the optional language tag

    • createLiteralLang

      public static Node createLiteralLang(String string, String lang)
      Make a literal with specified language. The lexical form must not be null.

      If the lang contains "--" it is interpreted as including a base direction.

      Parameters:
      string - the lexical form of the literal
      lang - the optional language tag

    • createLiteralDirLang

      public static Node createLiteralDirLang(String string, String lang, String textDir)
      Make a literal with specified language and language direction. The lexical form must not be null. The language must not be null or "" if a non-direction is provided.
      Parameters:
      string - the lexical form of the literal
      lang - the optional language tag
      textDir - the optional language direction

    • createLiteralDirLang

      public static Node createLiteralDirLang(String string, String lang, TextDirection textDir)

    • createLiteral

      public static Node createLiteral(String lex, String lang, RDFDatatype dtype)
      Build a literal node.

      This is a convenience operation for passing in language and datatype without needing the caller to differentiate between the xsd:string, rdf:langString, rdf:dirLangString and other datatype cases.

      It calls createLiteralString(String), createLiteralDirLang(String, String, String) or createLiteralDT(String, RDFDatatype) as appropriate.

      Parameters:
      lex - the lexical form of the literal
      lang - the optional language tag or null or ""
      dtype - the type of the literal or null.

    • createLiteral

      public static Node createLiteral(String lex, String lang, String textDir, RDFDatatype dtype)
      Build a literal node.

      This is a convenience operation for passing in language and datatype without needing the caller to differentiate between the xsd:string, rdf:langString, and other datatype cases.

      It calls createLiteralString(String), createLiteralDirLang(String, String, String) or createLiteralDT(String, RDFDatatype) as appropriate.

      Parameters:
      lex - the lexical form of the literal
      lang - the optional language tag or null or ""
      textDir - the optional language direction or null
      dtype - the type of the literal or null.
