public class ASMContentHandler
extends DefaultHandler
implements Opcodes

A 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.

构造器详细资料

ASMContentHandler

public ASMContentHandler(OutputStream os,
                 boolean computeMax)

Constructs a new ASMContentHandler object.

参数:

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.

方法详细资料

toByteArray

public byte[] toByteArray()

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

返回:

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(String ns,
                String lName,
                String qName,
                Attributes list)
                        throws SAXException

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

指定者:

startElement 在接口中 ContentHandler

覆盖:

startElement 在类中 DefaultHandler

参数:

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.

抛出:

SAXException - if a parsing error is to be reported

endElement

public final void endElement(String ns,
              String lName,
              String qName)
                      throws SAXException

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

指定者:

endElement 在接口中 ContentHandler

覆盖:

endElement 在类中 DefaultHandler

参数:

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.

抛出:

SAXException - if a parsing error is to be reported

endDocument

public final void endDocument()
                       throws SAXException

Process notification of the end of a document and write generated bytecode into output stream.

指定者:

endDocument 在接口中 ContentHandler

覆盖:

endDocument 在类中 DefaultHandler

抛出:

SAXException - if parsing or writing error is to be reported.
