Hi Jitesh,
The problem is that I would like to do this in compile time, using errors or
warnings...

HI,
I have tried small example. We can have poincut to constructor and check if
it is default constructor OR prameterised constructor. If it is prameterised
constructor, throw error. See if this u want.
class constructorTest
{
int a = 0;
public static void main(String[] args)
{
constructorTest obj1 = new constructorTest();
constructorTest obj2 = new constructorTest(10);
System.out.println("Program Over!");
}
public constructorTest() {
System.out.println("Executing Default Constructor");
}
public constructorTest(int a) {
this.a = a;
System.out.println("Executing parameterised Constructor : a
= "+a);
}
}
aspect testaspect
{
pointcut myConstructor() : within(constructorTest) &&
execution(constructorTest+.new(..));
before (): myConstructor() {
Object[] args = thisJoinPoint.getArgs();
if(args.length == 0) {
System.out.println("Default Constructor");
}else {
System.out.println("Parameterised Constructor");
//throw error.
}
}
}
Jitesh

Possibly. Can you write an attempt at doing this and submit it to the
list?

Hi,
I would like to declare an error if any subtype of ClassA do not have a
default constructor.
Is it possible?
Thanks

Try this:
public class Andre {
public static void main(String[] args) {}
static class A {}
static class GoodA extends A { GoodA() {} }
static class BadA extends A { BadA(String s) {} }
static class WhoCares1 { WhoCares1() {} }
static class WhoCares2 { WhoCares2(String s) {} }
static aspect C {
pointcut p():
execution(A+.new(..)) && !execution(A+.new());
declare error: p() : "boooo!";
}
}
