Class XMLReaderFactory

java.lang.Object

org.eclipse.rdf4j.common.xml.XMLReaderFactory

public class XMLReaderFactory
extends Object

Factory class for creating an XMLReader. This factory tries to use the system property 'org.xml.sax.driver', if that fails it falls back on javax.xml.sax.parsers.SAXParserFactory. If the SAXParserFactory class can not be found (this can happen when using a Java 1.3 or older), or the initialization using SAXParserFactory fails otherwise, the factory falls back on the Xerces 2 SAX Parser.

Method Details

createXMLReader

public static XMLReader createXMLReader()
                                 throws SAXException

creates an org.xml.sax.XMLReader object. The method first tries to create the XMLReader object specified in the 'org.xml.sax.driver' system property. If that fails, it tries to use java.xml.parsers.SAXParserFactory. If that also fails, it tries to initialize the Xerces 2 SAX parser. If that also fails, a SAXException is thrown.

Returns:

an XMLReader

Throws:

SAXException - when no default XMLReader class can be found or instantiated.

createXMLReader

public static XMLReader createXMLReader(String name)
                                 throws SAXException
