- * In practice this means that you can make it appear as though {@code delegate} implements the
- * {@code clazz} interface, without this in practice being the case. As an example, if you
- * create an interface representing the {@link android.media.MediaPlayer}, you could pass this
- * interface in as the first argument, and a real {@link android.media.MediaPlayer} in as the
- * second argument, and now calls to the interface will be automatically sent on to the real
- * media player. The reason you may be interested in doing this in the first place is that this
- * allows you to test classes that have dependencies that are final or cannot be easily mocked.
