      • read

        public final void read​(Model model,
                       java.io.Reader r,
                       java.lang.String base)
        Description copied from interface: RDFReaderI
        It is usually a mistake to use this method. Read serialized RDF from a Reader and add the statements to a Model. It is generally better to use an InputStream if possible. RDFReaderI.read(Model,InputStream,String), otherwise there is a danger of a mismatch between the character encoding of say the FileReader and the character encoding of the data in the file.
        Specified by:
        read in interface RDFReaderI
        Parameters:
        model - The model to which statements are added.
        r - the reader from which to read
        base - The base to use when converting relative to absolute URI's. The base URI may be null if there are no relative URIs to convert. A base URI of "" may permit relative URIs to be used in the model unconverted.

      • read

        public final void read​(Model model,
                       java.lang.String url)
        Description copied from interface: RDFReaderI
        Read serialized RDF from a url and add the statements to a model.
        Specified by:
        read in interface RDFReaderI
        Parameters:
        model - the model to which statements should be added
        url - the url, as a string, from which the serialized RDF should be read.

        public final void read​(Model model,
                       java.io.InputStream in,
                       java.lang.String base)
        Description copied from interface: RDFReaderI
        Read serialized RDF from an InputStream and add the statements to a Model.
        Specified by:
        read in interface RDFReaderI
        Parameters:
        model - The model to which statements are added.
        in - The InputStream from which to read
        base - The base to use when converting relative to absolute URI's. The base URI may be null if there are no relative URIs to convert. A base URI of "" may permit relative URIs to be used in the model unconverted.

      • setProperty

        public final java.lang.Object setProperty​(java.lang.String propName,
                                          java.lang.Object propValue)
        Description copied from interface: RDFReaderI
        Set the value of a reader property.

        The behaviour of a reader may be influenced by setting property values. The properties and there effects may depend on the individual reader implementation.

        An RDFReader's behaviour can be influenced by defining property values interpreted by that particular reader class. The values for such properties can be changed by calling this method.

        No standard properties are defined. For the properties recognised by any particular reader implementation, see the documentation for that implementation.

        The built-in RDFReaders have properties as defined by:

        N-TRIPLE
        No properties.
        RDF/XML
        RDF/XML-ABBREV
        See JenaReader.setProperty(String,Object)
        Specified by:
        setProperty in interface RDFReaderI
        Parameters:
        propName - the name of the property
        propValue - the value of the property
        Returns:
        the previous value of the property, or null if there wasn't one
