Examples with ErrorHandler org.xml.sax.ErrorHandler used on opensource projects

Example 36 with ErrorHandler

use of org.xml.sax.ErrorHandler in project jena by apache.

the class ARPHandlers method setErrorHandler.

/**
     * Sets the error handler, for both XML and RDF parse errors. XML errors are
     * reported by Xerces, as instances of SAXParseException; the RDF errors are
     * reported from ARP as instances of ParseException. Code that needs to
     * distingusih between them may look like:
     * 
     * <pre>
     *    void error( SAXParseException e ) throws SAXException {
     *      if ( e instanceof com.hp.hpl.jena.rdf.arp.ParseException ) {
     *           ...
     *      } else {
     *           ...
     *      }
     *    }
     * </pre>
     * 
     * <p>
     * See the ARP documentation for ErrorHandler for details of the
     * ErrorHandler semantics (in particular how to upgrade a warning to an
     * error, and an error to a.errorError).
     * </p>
     * <p>
     * The Xerces/SAX documentation for ErrorHandler is available on the web.
     * </p>
     * 
     * @param eh
     *            The error handler to use.
     * @return The previous error handler.
