Interface RDFReaderI

All Known Implementing Classes:
NTripleReader, RDFXMLReader, RDFXMLReader0

public interface RDFReaderI
An RDFReader reads a serialized representation of RDF, e.g. RDF/XML or N-Triples and adds the statements to a model.
Legacy

Reading RDF is usually done via:

  • RDFDataMgr
  • RDFParser
  • Model.read
All of these will use the newer RIOT parsers, not implementations of this interface.
  • Method Details

    • read

      void read(Model model, Reader r, String base)
      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. 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.
      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

      void read(Model model, InputStream r, String base)
      Read serialized RDF from an InputStream and add the statements to a Model.
      Parameters:
      model - The model to which statements are added.
      r - 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.
    • read

      void read(Model model, String url)
      Read serialized RDF from a url and add the statements to a model.
      Parameters:
      model - the model to which statements should be added
      url - the url, as a string, from which the serialized RDF should be read.
    • setProperty

      Object setProperty(String propName, Object propValue)
      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 RDFXMLReader.setProperty(String,Object)
      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
    • setErrorHandler

      RDFErrorHandler setErrorHandler(RDFErrorHandler errHandler)
      Set an error handler for the reader
      Parameters:
      errHandler - the new error handler
      Returns:
      the previous error handler
