/**
|
|
||||||
<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.
