I feel there ought to be a neater way I can't quite think of, but
these are options:
import org.aspectj.lang.reflect.*;
public aspect Foo {
boolean around(): get(boolean value) {
boolean b = proceed();
System.out.println("around advice: "+b);
return b;
}
after(C target): get(boolean C.value) && target(target) {
try {
boolean b =
((FieldSignature)thisJoinPoint.getSignature()).getField().getBoolean(target);
System.out.println("before advice: "+b);
} catch (Exception e) {}
}
public static void main(String []argv) {
new C().run();
}
}
class C {
boolean value = true;
public void run() {
boolean b = value;
value= false;
b = value;
}
}
