Constructor Detail

ASMContentHandler

public ASMContentHandler(java.io.OutputStream os,
                         boolean computeMax)

Constructs a new 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.

Method Detail

toByteArray

public byte[] toByteArray()

Returns the bytecode of the class that was build with underneath class writer.

Returns:

the bytecode of the class that was build with underneath class writer or null if there are no classwriter created.

startElement

public final void startElement(java.lang.String ns,
                               java.lang.String localName,
                               java.lang.String qName,
                               org.xml.sax.Attributes list)
                        throws org.xml.sax.SAXException

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

Specified by:

startElement in interface org.xml.sax.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.

localName - - 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:

org.xml.sax.SAXException - if a parsing error is to be reported

endElement

public final void endElement(java.lang.String ns,
                             java.lang.String localName,
