RDFXMLWriterI
All Known Implementing Classes:
BaseXMLWriter, NTripleWriter, RDFXML_Abbrev, RDFXML_Basic

public interface RDFWriterI
RDFWriterI is an interface to RDF serializers.
Legacy

Writing RDF is usually done via:

  • RDFDataMgr
  • RDFWriterr
  • Model.write
All of these will use the newer RIOT writers, not implementations of this interface.

An RDFWriter is a class which serializes an RDF model to some RDF serialization language.

  • Field Details

  • Method Details

    • write

      void write(Model model, Writer out, String base)
      Caution: Serialize Model model to Writer out. It is often better to use an OutputStream and permit Jena to choose the character encoding. The charset restrictions on the Writer are defined by the different implementations of this interface. Typically using an OutputStreamWriter (e.g. a FileWriter) at least permits the implementation to examine the encoding. With an arbitrary Writer implementations assume a utf-8 encoding.
      Parameters:
      out - The Writer to which the serialization should be sent.
      model - The model to be written.
      base - the base URI for relative URI calculations. null means use only absolute URI's.
    • write

      void write(Model model, OutputStream out, String base)
      Serialize Model model to OutputStream out. The implementation chooses the character encoding, utf-8 is preferred.
      Parameters:
      out - The OutputStream to which the serialization should be sent.
      model - The model to be written.
      base - the base URI for relative URI calculations. null means use only absolute URI's. This is used for relative URIs that would be resolved against the document retrieval URL. Particular writers may include this value in the output.
    • setProperty

      Object setProperty(String propName, Object propValue)
      Set a property to control the behaviour of this writer.

      An RDFWriter's behaviour can be influenced by defining property values interpreted by that particular writer 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 writer implementation, see the documentation for that implementation.

      The built-in RDFWriters have properties as defined by:

      N-TRIPLE
      No properties.
      RDF/XML
      RDF/XML-ABBREV
      Parameters:
      propName - The name of the property.
      propValue - The new value of the property
      Returns:
      the old value for this property, or null if no value was set.
    • setErrorHandler

      RDFErrorHandler setErrorHandler(RDFErrorHandler errHandler)
      Set an error handler.
      Parameters:
      errHandler - The new error handler to be used.
      Returns:
      the old error handler
