Can AOP help me?

[platinumdragon]

Hi,

I have an issue resolving public and internal interfaces, and I am hoping AOP can help me. I've been through the documentation, but I'm hoping somebody with more experience in AOP can see a solution.

Basically, my question is this: Can I set the value of a method-level field with the value from the calling object? I am essentially looking for parameter functionality without the explicit parameter.

More specifically, I'm looking to do something like..

public interface PublicInterface
{
 public void callMe(String name);
}

@Stateless
public class Target implements PublicInterface
{
 public void callMe(String name)
 {
 CallerContext ctx = null;

 // Use valid ctx here...
 }
}

@Stateful
public class Caller implements PublicInterface
{
 private CallerContext ctx;
 private Target target;

 public void callMe(String name)
 {
 target.callMe(name);
 }
}

I could do this:

public interface PrivateInterface
{
 public void callMe(String name, CallerContext);
}

and make Target implement PrivateInterface instead, but I really hate the idea of maintaining another interface almost exactly the same, and without any compiler-level enforcement for changes to one interface or the other. Also in real life there's about 45 methods in PublicInterface *ugh*.

Any ideas would be appreciated. If I'm missing something basic, please be gentle :)

Thanks,
Mike
