     /**
27 |  |
      * <p>A specialized SAX2 XML parser that "parses" hierarchical
28 |  |
      * configuration objects.</p>
29 |  |
      * <p>This class mimics to be a SAX conform XML parser. Instead of parsing
30 |  |
      * XML documents it processes a <code>Configuration</code> object and
31 |  |
      * generates SAX events for the single properties defined there. This enables
32 |  |
      * the whole world of XML processing for configuration objects.</p>
33 |  |
      * <p>The <code>HierarchicalConfiguration</code> object to be parsed can be
34 |  |
      * specified using a constructor or the <code>setConfiguration()</code> method.
35 |  |
      * This object will be processed by the <code>parse()</code> methods. Note
36 |  |
      * that these methods ignore their argument.</p>
