| * <pre> |
| * JAXBContext context = JAXBContext.newInstance( "org.acme.foo" ); |
| * |
| * Unmarshaller unmarshaller = context.createUnmarshaller(); |
| * |
| * UnmarshallerHandler unmarshallerHandler = unmarshaller.getUnmarshallerHandler(); |

| * SAXParserFactory spf = SAXParserFactory.newInstance(); |
| * spf.setNamespaceAware( true ); |
| * |
| * XMLReader xmlReader = spf.newSAXParser().getXMLReader(); |
| * xmlReader.setContentHandler( unmarshallerHandler ); |
| * xmlReader.parse(new InputSource( new FileInputStream( XML_FILE ) ) ); |
| * |
| * MyObject myObject= (MyObject)unmarshallerHandler.getResult(); |
| * </pre> |
| * |
| * <p> |
| * This interface is reusable: even if the user fails to unmarshal |
| * an object, s/he can still start a new round of unmarshalling. |
