Adrian has been talking about getting Java 5 support into AspectJ. I can imagine how much work that has been, and I am impressed to hear that AspectJ 5 now supports full source compilation of Java 5 programs.
AJDT also has integrated in to Eclipse 3.1 M4 with full Java 5 support, eager parsing, and early error indications all working happily (not officially released).
Check out a SimpleAspect. Java 5 style:
import java.util.List;
@MyAnnotation
public aspect SimpleAspect {
int x;
static List myStringList;
public static void main(String[] args) {
for(String s:args) {
System.out.println(s);
myStringList.add(s);
}
C c = new C();
c.whatCsDoBest();
c.somethingElse();
c.myInt(5);
c.somethingElse(new Object(), new Object());
c.whoAmI();
D d = new D();
d.whoAmI();
}
pointcut annotatedExecution() :
execution(@MyAnnotation * *(..));
before() : annotatedExecution() {
System.out.println(thisJoinPoint + " has an annotation.");
}
before() : call(* myInt(..)) && args(int) {
System.out.println("Autoboxing match");
}
before(Object[] objects) : call(* somethingElse(Object...)) && args(objects) {
System.out.print("Varargs match: ");
for (Object o:objects) {
System.out.print(o + " ");
}
System.out.println();
}
before() : execution(C whoAmI()) {
System.out.println("Covariant match on execution(C whoAmI())");
}
before() : execution(D whoAmI()) {
System.out.println("Covariant match on execution(D whoAmI())");
}
}
class C {
@MyAnnotation
public void whatCsDoBest() {
}
public void somethingElse(Object... objects) {
}
public C whoAmI() {
return this;
}
Progress getAspectJ5Progress() {
return Progress.EXCELLENT;
}
public int myInt(Integer i) {
return i;
}
}
class D extends C {
public D whoAmI() {
return this;
}
}
@interface MyAnnotation {}
enum Progress { OK, GOOD, VERYGOOD, EXCELLENT }
