Hi Dave,
that's a bit hard to tell without context; generally, Python can
construct wrapper code for std::vector that makes those iterable, and
handles the interna a bit different, but with PMTs the non-bracket
method of access might work:
your_vector_of_pmts_in_python.at(index)
if that works, you can tell SWIG that your vector type should be an
iterable; try going into your OOT's swig/ootname.i and add a
%include <std_vector.i>
pretty much at the beginneing, and make sure to have in your %{%}:
%{
#include <pmt/pmt.h>
#include <vector>
%}
and further down, declare
%template(ootname_vector_pmt_t) std::vector<pmt::pmt_t>;
And then hope that SWIG does what you want :(
Best regards,
Marcus
