Constructor Detail

ASMContentHandler

public ASMContentHandler(ClassVisitor cv)

Constructs a new ASMContentHandler object.

Parameters:

cv - class visitor that will be called to reconstruct the classfile using the XML stream.

Method Detail

startElement

public final void startElement(String ns,
                String lName,
                String qName,
                Attributes list)
                        throws SAXException

Process notification of the start of an XML element being reached.

Specified by:

startElement in interface ContentHandler

Overrides:

startElement in class org.xml.sax.helpers.DefaultHandler

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

endElement

Specified by:

endElement in interface ContentHandler

Overrides:

endElement in class org.xml.sax.helpers.DefaultHandler

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.
