Thank you, this was very helpful.
Following that, I have another question -
This code prints errors. How can I avoid them?
code:
spot::bdd_dict_ptr dict = spot::make_bdd_dict();
spot::kripke_ptr model = std::make_shared<MyKripke>(dict);
model->register_ap("p");
errors:
some maps are not empty
Variable Map:
0 Var[p] x1 { 0xb32fd0 }
1 Free
Anonymous lists: [0]
Free list: (1, 1)
Aborted
This is the bdd_dict telling you that BDD variable #0 is still
associated to atomic proposition "p" for the object 0xb32fd0 (which in
this case should be your model).
You probably need
get_dict()->unregister_all_my_variables(this);
in the destructor of MyKripke.
I realize now that since we introduced twa::register_ap() to hide most
of the interactions with the bdd_dict, it should probably be cleaner
if unregister_all_my_variables() was called in the twa destructor so
that it is not necessary to call it in the destructor of every
subclass. I'll have a look at that.
