User development, A new message was posted in the thread "determining if code passed to insertAfter() is executed after an exception handler or before normal return": http://community.jboss.org/message/526689#526689 Author : Arvind K Profile : http://community.jboss.org/people/megalodon Message: -------------------------------------------------------------- I didnt know much about CtMethod.instrument() and ExprEditor and its edit methods before. You can use them to solve the above problem: // Suppose you want to know from where the insertBefore code of 'myCtMethod' is running, You can add a boolean // variable to the class for this purpose (unfortunately, we need one for every such method). In our case, I call // it 'inHandler'. Set it to false upon initialization.     myCtMethod.instrument(new ExprEditor() {    public void edit(Handler myHandler) throws CannotCompileException {     try {         // insertBefore inserts the statement before the catch block is entered. You can even change the exception here, i think.      // Here I set inHandler to true signifying entry into the catch block.      myHandler.insertBefore("inHandler = true;");  // inHandler is an (added) field of the CtClass containing myCtMethod           // Below statement prints some description of the handler object, if needed.      myHandler.insertBefore("System.out.println(\"Instrumentation detected presence of a Handler for " + myHandler.getType().getName() + " at line number " + myHandler.getLineNumber()+"\");");     } catch (NotFoundException ntfnde) {      ntfnde.printStackTrace();     }    }   });     // The below if statement will distinguish between normal code and exception handler code and execute accordingly   sayCtM.insertAfter("if (inHandler == true) System.out.println(\"Running within a handler.\"); else System.out.println(\"Running in normal code\");");   -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/526689#526689
