Hi Owen,

 

Traced is a protected interface that is defined within Log4jExecutionTracing itself. You just use the aspect by extending it and using declare parents to make the relevant classes you want to trace implement traced, as in:

 

public aspect MyLog4jExecutionTracing extends Log4jExecutionTracing {

     declare parents: com.bigboxco.myapp..* implements Traced;

}

Subject: [aspectj-users] question on ajlib:

 

With regards to ajlib:

http://fisheye.codehaus.org/browse/ajlib-incubator/org.codehaus.ajlib

 

There is a class Log4jExecutionTracing not covered in the unit tests and for which there are no examples of its usage. It uses a class called "Traced" that I don't see anywhere and I *think* that is at the core of my not comprehending how to use this class.

 

Basically if I have a test tracing aspect like this it works great (DummyObject is the class whose methods are to be traced):

 

package com.AjlibTest;

import org.codehaus.ajlib.util.tracing.ExecutionTracing;

public aspect TestTraceAspect extends ExecutionTracing

{

    public pointcut scope() : within(DummyObject);

    before(): scope()

    {

         System.out.println("Tracing");

    }

}

 

But if I change ExecutionTracing to Log4jExecutionTracing it doesn't weave anything (advice defined in com.AjlibTest.TestTraceAspect has not been applied [Xlint:adviceDidNotMatch]).

 

much appreciated,

Owen
