Annotation Type ConstructorArg


  • @Retention(RUNTIME)
    @Target(PARAMETER)
    public @interface ConstructorArg
    Annotation for the auto injection of immutable beans. As with Java up to version 8 is not possible to retrieve the constructor's parameter name through reflection, this annotation needs to be specified next to each one of them. e.g. public class Square { private final int x; private final int y; public Square(@ConstructorArg("x") final int x, @ConstructorArg("y") final int y) { this.x = x; this.y = y; } }
