Hi,
I was trying to make some simple mixins using AspectJ.
My scenario is the following. I have an (abstract) class, let's say Foo,
that implements the interface Bar, and that has a template method in which
it calls the methods provided by the Bar interface.
interface Bar {
String barMethod();
}
abstract class Foo implements Bar {
public void run() {
System.out.println( barMethod() );
}
}
so, I would like to have various mixins which can provide the Bar
implementation, and only choose one of them to be actually merged in.
I was trying to adopt the approach of writing them in the following way:
public privileged aspect BarAspect_First {
public String Foo.barMethod() {
return "First";
}
}
public privileged aspect BarAspect_Second{
public String Foo.barMethod() {
return "Second";
}
}
but clearly Eclipse/AJDT complains about conflict inter-type declarations.
So going back to my question, how do I declare the mixins and them be able
to specify which one to actually be used?
Thanks in advance for any suggestion.
Regards,
Alessio Pace.
