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. + + @since 1.6 +*/ +@Documented @Target(CONSTRUCTOR) @Retention(RUNTIME) +public @interface ConstructorProperties { + /** +

The getter names.

+ @return the getter names corresponding to the parameters in the + annotated constructor. + */ + String[] value(); +}
