[aspectj-users] Pointcut expression for matching generic interface

[Jan <jan@xxxxxxxxxx>]

Dear AspectJ users,

Considering the following interface:

public interface IFooService<T extends Foo>
{
 public T create();
 public void save (T foo);
}

with object classes:

class Foo {}
class Bar extends Foo {}

and factory implementation

public class BarService implements IFooService<Bar>
{
 public Bar create() { return new Bar(); }
 public void save (Bar bar)
 {
   // save the object
 }
}

How would one formulate a pointcut expression matching "any method on 
implementations of IFooService"?

I tried the following:
execution(* IFooService.*(..))

but that would only match the create() function, not the save() 
function!!! I suspect this is due to the type erasure that comes into 
play when using generics; IFooService will contain a save(Foo) method, 
while BarService implements a save(Bar) method....these don't match 
exactly.

Still, I'd like to formulate "any implementation of IFooService, with 
any generic type".... ideas?
