The valueOf method in Enum subclasses is static, so Enum itself can't
usefully declare it. But the description of the Enum class could say
in text what the generated methods are, rather than referring the
reader to the JLS without even a link. If you forget what the methods
are you can always look in any enum, such as Thread.State
but you shouldn't have to.
