/**
|
|
<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 {
|
|
@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.
