/**
   <p>An annotation on a constructor that shows how the parameters of
   that constructor correspond to the constructed object's getter
   methods.  For example:

   <blockquote>
<pre>
   public class Point {
       &#64;ConstructorProperties({"x", "y"})
       public Point(int x, int y) {
           this.x = x;
           this.y = y;
       }

       public int getX() {
           return x;
       }

       public int getY() {
           return y;
       }

       private final int x, y;
   }
</pre>
</blockquote>

   The annotation shows that the first parameter of the constructor
   can be retrieved with the {@code getX()} method and the second with
   the {@code getY()} method.  Since parameter names are not in
   general available at runtime, without the annotation there would be
   no way to know whether the parameters correspond to {@code getX()}
   and {@code getY()} or the other way around.
