Re: [aspectj-users] adding synchronization/thread support in code using

[Wes Isberg <wes@xxxxxxxxxxxxxx>]

You can't change a method signature.  (There's a
FAQ entry on point.)  But you can wrap a join point
using around advice -- e.g.,

   Object around() : execution(* MyClass.*(..)) {
      synchronized(someLock) {
           return proceed();
      }
    }

   // or, for non-static methods
   Object around(MyClass myClass): target(myClass)
         && execution(* MyClass.*(..)) {
      synchronized(myClass.lock) {
           return proceed();
      }
    }

See also the examples in the distribution
(coordination package, spacewar/*Synchronization.java).
