ValidatorImpl

• java.lang.Object
  • javax.xml.validation.Validator

Fields Summary
private final ValidatorHandlerImpl	handler The actual validation will be done by this object.
private Transformer	identityTransformer1 Lazily created identity transformer.
private TransformerHandler	identityTransformer2
private final ErrorHandler	errorForwarder Forwards the error to the {@link ValidatorHandler}. If the {@link ValidatorHandler} doesn't have its own {@link ErrorHandler}, behave draconian.
private final EntityResolver	resolutionForwarder Forwards the entity resolution to the {@link ValidatorHandler}. If the {@link ValidatorHandler} doesn't have its own {@link DOMResourceResolver}, let the parser do the resolution.

Constructors Summary
ValidatorImpl(ValidatorHandlerImpl _handler) this.handler = _handler;

Methods Summary
public org.xml.sax.ErrorHandler	getErrorHandler() return handler.getErrorHandler();
public org.w3c.dom.ls.LSResourceResolver	getResourceResolver() return handler.getResourceResolver();
private void	process(javax.xml.transform.sax.SAXSource source, javax.xml.transform.sax.SAXResult result) Parses a {@link SAXSource} potentially to a {@link SAXResult}. if( result!=null ) { handler.setContentHandler(result.getHandler()); } try { XMLReader reader = source.getXMLReader(); if( reader==null ) { // create one now SAXParserFactory spf = SAXParserFactory.newInstance(); spf.setNamespaceAware(true); try { reader = spf.newSAXParser().getXMLReader(); } catch( Exception e ) { // this is impossible, but better safe than sorry throw new FactoryConfigurationError(e); } } reader.setErrorHandler(errorForwarder); reader.setEntityResolver(resolutionForwarder); reader.setContentHandler(handler); InputSource is = source.getInputSource(); reader.parse(is); } finally { // release the reference to user's handler ASAP handler.setContentHandler(null); }
private void	process(javax.xml.transform.dom.DOMSource source, javax.xml.transform.dom.DOMResult result) Parses a {@link DOMSource} potentially to a {@link DOMResult}. if( identityTransformer1==null ) { try { SAXTransformerFactory tf = (SAXTransformerFactory)SAXTransformerFactory.newInstance(); identityTransformer1 = tf.newTransformer(); identityTransformer2 = tf.newTransformerHandler(); } catch (TransformerConfigurationException e) { // this is impossible, but again better safe than sorry throw new TransformerFactoryConfigurationError(e); } } if( result!=null ) { handler.setContentHandler(identityTransformer2); identityTransformer2.setResult(result); } try { identityTransformer1.transform( source, new SAXResult(handler) ); } catch (TransformerException e) { if( e.getException() instanceof SAXException ) throw (SAXException)e.getException(); throw new SAXException(e); } finally { handler.setContentHandler(null); }
public void	reset() handler.reset(); // I don't think this is necessary, but I don't think it hurts either. // so reset just for the kick. if(identityTransformer1!=null) { identityTransformer1.reset(); }
public void	setErrorHandler(org.xml.sax.ErrorHandler errorHandler) handler.setErrorHandler(errorHandler);
public void	setResourceResolver(org.w3c.dom.ls.LSResourceResolver resolver) handler.setResourceResolver(resolver);
public void	validate(javax.xml.transform.Source source, javax.xml.transform.Result result) if( source instanceof DOMSource ) { if( result!=null && !(result instanceof DOMResult) ) throw new IllegalArgumentException(result.getClass().getName()); process( (DOMSource)source, (DOMResult)result ); return; } if( source instanceof SAXSource ) { if( result!=null && !(result instanceof SAXResult) ) throw new IllegalArgumentException(result.getClass().getName()); process( (SAXSource)source, (SAXResult)result ); return; } if( source instanceof StreamSource ) { if( result!=null ) throw new IllegalArgumentException(result.getClass().getName()); StreamSource ss = (StreamSource)source; InputSource is = new InputSource(); is.setByteStream(ss.getInputStream()); is.setCharacterStream(ss.getReader()); is.setPublicId(ss.getPublicId()); is.setSystemId(ss.getSystemId()); process( new SAXSource(is), null ); return; } throw new IllegalArgumentException(source.getClass().getName());
