As is often the case with such "models", there is nothing you could write down, at least not easily, and without nasty arrays of numbers. Those are things that computers are great at working with, but there is really nothing to look at. It is the same thing with a spline model. Just a bunch of coefficients, that won't make any sense to you. So there is nothing to "get". You can use it, predict with it, save it, store it, all in the container that allows you to do all of these things.
