Re: [aspectj-users] Join point for directly accessing a field?

[Alexander Kriegisch <Alexander@xxxxxxxxxxxxxx>]

You want to familiarise yourself with get() and set() pointcut types:

https://eclipse.dev/aspectj/doc/latest/progguide/progguide.html#quick-pointcuts
https://eclipse.dev/aspectj/doc/latest/progguide/progguide.html#_field_related_pointcuts

For example, assuming all this code is inside file A.aj and compiled
with ajc:

public class A {
  public static int a = 42;

  public static void main(String[] args) {
    new B().b();
  }
}

class B {
  void b() {
    System.out.println(A.a);
  }
}

aspect MyAspect {
  before() : get(* A.a) {
    System.out.println(thisJoinPoint);
  }
}

Console log:

get(int A.a)
42

In your pseudo code, class A is static, as if it was contained in
another class. In that case, the class qualifier in the pointcut would
need to contain the outer class.
