Where are parameters stored within ForneyLab

Consider the following code snippet:

using ForneyLab
g = FactorGraph()
@RV x ~ Bernoulli(0.7)

My question is: in what data structure is 0.7 stored? I found that Bernoulli is a struct by examining the ForneyLab source code. So far, I have not been able to access “0.7” by examining with g or x from the command line. I am working in Jupyterlab. For example,



Variable(:clamp_1, Edges:
Edge belonging to variable clamp_1: ( clamp_1.i[out] )----( bernoulli_1.i[p] ).

I am simply trying to better understand the internal structure of this package, which I find quite interesting. Thank you.
