[André Dantas Rocha <ad-rocha@xxxxxxxxxx>]

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.
		}
	}
}
