title: Class transformer in JAVA ASM - can it be generated?
body: <p>I'd like to start using Java ASM to transform classes in my project - to add one <code>String</code> argument to some methods and send log with this argument.</p>
  
  <p>On <a href="http://asm.ow2.org/index.html" rel="nofollow">asm website</a> I've read</p>
  
  <blockquote>
    <p>If you want to implement a class transformer, write two Java source
    files (before and after transformation) and use the compare view of
    the plugin in ASMifier mode to compare the equivalent ASM code.</p>
  </blockquote>
  
  <p>But I find using Java ASM extremely hard. Is there any tool which can generate <code>class transformer</code>? It would be very useful! </p>
