* A helper that exposes package-private fields in this package for reflective lookup.
|
|
* <p>
|
|
* By adding a subclass of this to every package in the model, we can write generic code that can
|
|
* access fields with package private access. The other alternative is to call
|
|
* {@link Field#setAccessible} with {@code true} on any such Field objects, but that does not work
|
|
* reliably in Google App Engine cross-package because of its custom security manager
|
|
* implementation.
