+/**
+   <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.
