org.mulgara.jena.rdf.arp.impl
Class XMLHandler

java.lang.Object
  extended by org.xml.sax.helpers.DefaultHandler
      extended by org.mulgara.jena.rdf.arp.impl.XMLHandler
All Implemented Interfaces:
ARPErrorNumbers, Names, ContentHandler, DTDHandler, EntityResolver, ErrorHandler, LexicalHandler
Direct Known Subclasses:
RDFXMLParser, SAX2RDFImpl
public class XMLHandler
extends DefaultHandler
implements ARPErrorNumbers, Names

This class converts SAX events into a stream of encapsulated events suitable for the RDF parser. In effect, this is the RDF lexer. updates by kers to handle exporting namespace prefix maps.
