Re: [aspectj-users] Intercepting field access and thread-safety

[Andy Clement <andrew.clement@xxxxxxxxx>]

Hi,

Sorry for the late reply, we are all at Spring One 2GX.  How about:

public class Code {
  int i = 5;
  public static void main(String[] argv) {
    new Code().foo();
  }
  public void foo() {
    System.out.println(i);
  }
}

aspect X {
  int around(): get(int Code.i) {
    return 42;
  }
}

Does that do what you want?

Andy
