Once populated, ClassMetadata instances are usually cached in a serialized form.
IMPORTANT NOTE:
The fields of this class are only public for 2 reasons:
1) To allow fast READ access.
2) To drastically reduce the size of a serialized instance (public/protected members
get the whole class name, namespace inclusive, prepended to every property in
the serialized representation).
