public class ASMContentHandler extends DefaultHandler implements Opcodes
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.

ClassWriter
used to write
class bytecode. Label
instances for current method. ASMContentHandler
object.
Parameters: os output stream to write generated class. computeMax true if the maximum stack size and the
maximum number of local variables must be automatically computed.
This value is passed to ClassWriter
instance.
Throws: SAXException if parsing or writing error is to be reported.
Parameters: ns - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed. lName - The local name (without prefix), or the empty string if Namespace processing is not being performed. qName - The qualified XML 1.0 name (with prefix), or the empty string if qualified names are not available.
Throws: SAXException if a parsing error is to be reported
Parameters: ns - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed. lName - The local name (without prefix), or the empty string if Namespace processing is not being performed. qName - The qualified name (with prefix), or the empty string if qualified names are not available. list - The attributes attached to the element. If there are no attributes, it shall be an empty Attributes object.
Throws: SAXException if a parsing error is to be reported
Returns: the bytecode of the class that was build with underneath class writer or null if there are no classwriter created.
