javax.xml.bind Interface UnmarshallerHandler
- 所有父接口:
- ContentHandler
public interface UnmarshallerHandler
- extends ContentHandler
Unmarshaller implemented as SAX ContentHandler.
Applications can use this interface to use their JAXB provider as a component in an XML pipeline. For example:
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();
This interface is reusable: even if the user fails to unmarshal an object, s/he can still start a new round of unmarshalling.

getResult
Object getResult() throws JAXBException, IllegalStateException
- Obtains the unmarshalled result.
This method can be called only after this handler
receives the endDocument SAX event.
- 返回:
- always return a non-null valid object which was unmarshalled.
- 抛出异常:
IllegalStateException- if this method is called before this handler receives the endDocument event.JAXBException- if there is any unmarshalling error. Note that the implementation is allowed to throw SAXException during the parsing when it finds an error.
