/**
An annotation on a constructor that shows how the parameters of
that constructor correspond to the constructed object's getter
methods. For example:
public class Point {
@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;
}
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.
