Re: Get TypeNames of Variadic Templates

[Christian Köstlin]

Hi Philippe,

wonderful solution. I also added
T get(T)() {
  return components[staticIndexOf!(T, Children)];
}
to the class to get the Children out by type (works as long as there is 
only one child of each type in the tuple).

thanks a lot!!!

Hi Christian,

My question is, is it possible to generate this with some mapping algorithm,
instead of writing this loop by hand?

You can create a tuple:

class Component(Children...) {
     Children components;  //<- Here

     this() {}

     static if (Children.length>  0)
         this(Children args)
         {
             components = args;
         }
}

void main()
{
     auto c = new Component!(int, double, Component!(string));
     writeln(c.components);

     c.components[0] = 1;
     c.components[1] = 3.14159;
     c.components[2] = new Component!(string)("abc");

     writeln(c.components);
     writeln(c.components[2].components);
}
