public class NumberTranslatorFactory
extends Object
implements TranslatorFactory<Number,Object>

Numbers are funky in the datastore. You can save numbers of any size, but they always retrieve as Long. For the hell of it, we also handle String in the datastore by trying to parse it.

Not a ValueTranslatorFactory because Numbers are not assignable to primitives. Java lame.
