ASMContentHandler
public class ASMContentHandler extends DefaultHandler implements Opcodes(Code)
A org.xml.sax.ContentHandler ContentHandler that transforms XML document into Java class file. This class can be feeded by any kind of SAX 2.0 event producers, e.g. XML parser, XSLT or XPath engines, or custom code.
