Constructors Summary
SAXParserImpl(SAXParserFactoryImpl spf, Hashtable features) Create a SAX parser with the associated features param features Hashtable of SAX features, may be null this(spf, features, false);
SAXParserImpl(SAXParserFactoryImpl spf, Hashtable features, boolean secureProcessing) Create a SAX parser with the associated features param features Hashtable of SAX features, may be null // Instantiate a SAXParser directly and not through SAX so that we use the right ClassLoader xmlReader = new JAXPSAXParser(this); // JAXP "namespaceAware" == SAX Namespaces feature // Note: there is a compatibility problem here with default values: // JAXP default is false while SAX 2 default is true! xmlReader.setFeature0(NAMESPACES_FEATURE, spf.isNamespaceAware()); // SAX "namespaces" and "namespace-prefixes" features should not // both be false. We make them opposite for backward compatibility // since JAXP 1.0 apps may want to receive xmlns* attributes. xmlReader.setFeature0(NAMESPACE_PREFIXES_FEATURE, !spf.isNamespaceAware()); // Avoid setting the XInclude processing feature if the value is false. // This will keep the configuration from throwing an exception if it // does not support XInclude. if (spf.isXIncludeAware()) { xmlReader.setFeature0(XINCLUDE_FEATURE, true); } // If the secure processing feature is on set a security manager. if (secureProcessing) { xmlReader.setProperty0(SECURITY_MANAGER, new SecurityManager()); } // Set application's features, followed by validation features. setFeatures(features); // If validating, provide a default ErrorHandler that prints // validation errors with a warning telling the user to set an // ErrorHandler. if (spf.isValidating()) { fInitErrorHandler = new DefaultValidationErrorHandler(); xmlReader.setErrorHandler(fInitErrorHandler); } else { fInitErrorHandler = xmlReader.getErrorHandler(); } xmlReader.setFeature0(VALIDATION_FEATURE, spf.isValidating()); // Get the Schema object from the factory this.grammar = spf.getSchema(); if (grammar != null) { XMLParserConfiguration config = xmlReader.getXMLParserConfiguration(); XMLComponent validatorComponent = null; /** For Xerces grammars, use built-in schema validator. **/ if (grammar instanceof XSGrammarPoolContainer) { validatorComponent = new XMLSchemaValidator(); fSchemaValidationManager = new ValidationManager(); fUnparsedEntityHandler = new UnparsedEntityHandler(fSchemaValidationManager); config.setDTDHandler(fUnparsedEntityHandler); fUnparsedEntityHandler.setDTDHandler(xmlReader); xmlReader.setDTDSource(fUnparsedEntityHandler); fSchemaValidatorComponentManager = new SchemaValidatorConfiguration(config, (XSGrammarPoolContainer) grammar, fSchemaValidationManager); } /** For third party grammars, use the JAXP validator component. **/ else { validatorComponent = new JAXPValidatorComponent(grammar.newValidatorHandler()); fSchemaValidatorComponentManager = config; } config.addRecognizedFeatures(validatorComponent.getRecognizedFeatures()); config.addRecognizedProperties(validatorComponent.getRecognizedProperties()); config.setDocumentHandler((XMLDocumentHandler) validatorComponent); ((XMLDocumentSource)validatorComponent).setDocumentHandler(xmlReader); xmlReader.setDocumentSource((XMLDocumentSource) validatorComponent); fSchemaValidator = validatorComponent; } // Initial EntityResolver fInitEntityResolver = xmlReader.getEntityResolver();

public org.xml.sax.Parser	getParser() // Xerces2 AbstractSAXParser implements SAX1 Parser // assert(xmlReader instanceof Parser); return (Parser) xmlReader;
public java.lang.Object	getProperty(java.lang.String name) returns the particular property requested for in the underlying implementation of org.xml.sax.XMLReader. return xmlReader.getProperty(name);
public javax.xml.validation.Schema	getSchema() return grammar;
public org.xml.sax.XMLReader	getXMLReader() Returns the XMLReader that is encapsulated by the implementation of this class. return xmlReader;

public boolean	isValidating() try { return xmlReader.getFeature(VALIDATION_FEATURE); } catch (SAXException x) { throw new IllegalStateException(x.getMessage()); }
public boolean	isXIncludeAware() Gets the XInclude processing mode for this parser return the state of XInclude processing mode try { return xmlReader.getFeature(XINCLUDE_FEATURE); } catch (SAXException exc) { return false; }

private void	setFeatures(java.util.Hashtable features) Set any features of our XMLReader based on any features set on the SAXParserFactory. XXX Does not handle possible conflicts between SAX feature names and JAXP specific feature names, eg. SAXParserFactory.isValidating() if (features != null) { for (Enumeration e = features.keys(); e.hasMoreElements();) { String feature = (String)e.nextElement(); boolean value = ((Boolean)features.get(feature)).booleanValue(); xmlReader.setFeature0(feature, value); } }
public void	setProperty(java.lang.String name, java.lang.Object value) Sets the particular property in the underlying implementation of org.xml.sax.XMLReader. xmlReader.setProperty(name, value);
