Example 22 with ErrorListener

use of javax.xml.transform.ErrorListener in project j2objc by google.

the class XPathParser method errorForDOM3.

   * This method is added to support DOM 3 XPath API.

   * This method is exactly like error(String, Object[]); except that
   * the underlying TransformerException is 
   * XpathStylesheetDOM3Exception (which extends TransformerException).
   * <p>
   * So older XPath code in Xalan is not affected by this. To older XPath code
   * the behavior of whether error() or errorForDOM3() is called because it is
   * always catching TransformerException objects and is oblivious to
   * the new subclass of XPathStylesheetDOM3Exception. Older XPath code 
   * runs as before.
   * <p>
   * However, newer DOM3 XPath code upon catching a TransformerException can
   * can check if the exception is an instance of XPathStylesheetDOM3Exception
   * and take appropriate action.
   * 
   * @param msg An error msgkey that corresponds to one of the constants found 
   *            in {@link org.apache.xpath.res.XPATHErrorResources}, which is 
   *            a key for a format string.
   * @param args An array of arguments represented in the format string, which 
   *             may be null.
   *
   * @throws TransformerException if the current ErrorListoner determines to
