I need to construct a Trinomial Tree for Hull-White model. Looking at the docs:
I see many modules or members that match trinomial.
How would I know which to use?
Or if I do something like:
model = HullWhite(term_structure);
How would I know if the
TreeSwaptionEngine has selected a Trinomial tree and is it possible to print the tree or visualize with Graphviz?
I've looked at the examples here but it is still not obvious how these map back to the C++
