SAXClassAdapter

public final class SAXClassAdapter extends Object implements ClassVisitor
A {@link oracle.toplink.libraries.asm.ClassVisitor ClassVisitor} that generates SAX 2.0 events from the visited class. It can feed any kind of {@link org.xml.sax.ContentHandler ContentHandler}, e.g. XML serializer, XSLT or XQuery engines.
