Can I use apply() with constructor to pass arbitrary number of parameters

Question

I\'ve got a function wich can accept a varible number of parameter with a rest operator.

I want create an object passing the argument collected with the rest opera

Unfortunately no. There is no way to make apply work for constructor. What is done generally is to prepare a number of call based on the number of arguments :

public function myFunc(...arg):Myclass {
  switch (arg.length) {
    case 0:return new MyClass();
    case 1:return new MyClass(arg[0]);
    case 2:return new MyClass(arg[0], arg[1]);

    //... etc

    case n:return new MyClass(arg[0], arg[1],..,arg[n]);
    default: throw new Error("too much arguments in myFunc");
  }
}
