[aspectj-users] Re: How do I generate a method Signature programatically

[Olle Hallin <olle.hallin@xxxxxx>]

I found the answer myself:

import org.aspectj.lang.JoinPoint;

import org.aspectj.lang.Signature;

import org.aspectj.runtime.reflect.Factory;

    private void enumeratePublicMethods(String className) {

        try {

            Class<? extends Object> clazz = Class.forName(className);

            for (Method m : clazz.getMethods()) {

                JoinPoint.StaticPart jpsp = Factory.makeEncSJP(m);

                String methodName = jpsp.getSignature().toLongString();

                unusedMethods.add(methodName);

            }

        } catch (ClassNotFoundException e) {

            e.printStackTrace(System.err);

        }

    }

Hi,

I'm working on my DeadCodeDetector aspect in my spare time, and now it detects constructed but unused classes (by using a combination of staticinitialization and execution pointcuts).

Now I want to continue and make it detect unused public methods.

For this I intend to use reflection in the after class loading advice, and insert one string for each public method in a Set<String> unusedMethods, which later can be removed by the after public method execution advice.

So what I need is to transform a java.lang.reflect.Method to a org.aspectj.lang.Signature. How do I do that?
