public interface UnmarshallerHandler extends ContentHandler
应用程序可以使用此接口将其JAXB提供程序用作XML管道中的组件。 例如:
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();
该界面是可重用的:即使用户未能解组对象,他/他仍然可以开始新一轮的解组。
Unmarshaller.getUnmarshallerHandler()
Modifier and Type | Method and Description |

getResult()
获得未组织的结果。

characters, endDocument, endElement, endPrefixMapping, ignorableWhitespace, processingInstruction, setDocumentLocator, skippedEntity, startDocument, startElement, startPrefixMapping
Object getResult() throws JAXBException, IllegalStateException
IllegalStateException
- 如果在此处理程序接收到endDocument事件之前调用此方法。
JAXBException
- 如果有任何解组错误。
请注意,在解析过程中发现错误时,允许实现抛出SAXException。
