    • read

      public final void read(Model model, Reader r, 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, 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.

    • read

      public final void read(Model model, InputStream in, 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.

    • setErrorHandler

      public final RDFErrorHandler setErrorHandler(RDFErrorHandler errHandler)
      Description copied from interface: RDFReaderI
      Set an error handler for the reader
      Specified by:
      setErrorHandler in interface RDFReaderI
      Parameters:
      errHandler - the new error handler
      Returns:
      the previous error handler

    • setProperty

      public final Object setProperty(String propName, 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
