Question

I create my enums through reflection, for that I add to each enum an inner class which implements the abstract factory. Now I want to access this inner class in order to invoke the method:

@Factory(FooFactory.class)
public enum Foo {

     FOO, BAR;

     public class FooFactory implements AbstractFactory<Foo> {

          public Foo create(String value) {
               return valueOf(value.toUpperCase());
          }
     }
}

The definition of @Factory is:

@Retention(RetentionPolicy.RUNTIME)
public @interface Factory {

        Class<?> value();
}

With this, however, I receive the following error:

Class cannot be resolved to a type FooFactory.java

When I try @Factory(Foo$FooFactory.class) I receive the error:

The nested Foo$FooFactory cannot be referneced using its binary name.

So is it even possible to reference a nested class?

From the comments… apparently

@Factory(Foo.FooFactory.class)

was needed.
