Description
Class Summary | |
---|---|
ASMContentHandler | A ContentHandler
that transforms XML document into Java class file. |
Processor | Processor is a command line tool that can be used for bytecode waving directed by XSL transformation. |
SAXClassAdapter | A ClassVisitor that generates SAX 2.0
events from the visited class. |
SAXCodeAdapter | A CodeVisitor that generates SAX 2.0
events from the visited code. |
Provides SAX 2.0 adapters for ASM visitors that can be used to convert bytecode to and from XML. These adapters can be chained with other SAX compliant content handlers and filters, eg. XSLT or XQuery engines. This package is bundled as a separate asm-xml.jar library and requires asm.jar.
ASMContentHandler and SAXClassAdapter/SAXCodeAdapter are using asm-xml.dtd. Here is the example of bytecode to bytecode XSLT transformation.
SAXTransformerFactory saxtf = ( SAXTransformerFactory) TransformerFactory.newInstance(); Templates templates = saxtf.newTemplates( xsltSource); TransformerHandler handler = saxtf.newTransformerHandler( templates); handler.setResult( new SAXResult( new ASMContentHandler( outputStream, computeMax))); ClassReader cr = new ClassReader( bytecode); cr.accept( new SAXClassAdapter( handler, cr.getVersion(), false), false);See JAXP and SAX documentation for more detils.
There are few illustrations of the bytecode transformation with XSLT in examples directory. The following XSLT procesors has been tested.
