*
* <pre>
* public class Foo {
* public interface Factory {
* Foo create(int a);
* }
* @Inject
* Foo(Logger log, @Assisted int a) {...}
* }
* </pre>
*
* Just pass {@code Foo.Factory.class} to this method. The factory will be
* generated to return its one return type as declared in the creation method.
*
* @param factory interface which specifies the bean factory method.
