c++ - SWIG: How to wrap boost::shared_ptr to std::vector? -

i have c++ code returns boost::shared_ptr std::vector, unable swig wrap correctly make object iterable in python. without boost::shared_ptr works fine. know how wrap vector when it's inside shared_ptr?

here example demonstrating problem:

%module example  %include <std_vector.i> %include <boost_shared_ptr.i>  %shared_ptr(inner) %shared_ptr(innervector)  %inline %{ #include <boost/shared_ptr.hpp> #include <vector>  struct inner {   int dummy; }; typedef std::vector< boost::shared_ptr<inner> > innervector; typedef boost::shared_ptr<innervector> innervectorptr;  innervectorptr getvectorptr() {   innervectorptr v(new innervector());   boost::shared_ptr<inner> i(new inner);   i->dummy = 222;   v->push_back(i);   return v; }  %}  %template(innervector) ::std::vector< boost::shared_ptr<inner> >; 

and example python script:

import example  v = example.getvectorptr() print 'vector is:', v in v:      print 'instance is:',      print 'value is:', i.dummy 

which me, says this:

vector is: <swig object of type 'innervectorptr *' @ 0x1127270> traceback (most recent call last):   file "test.py", line 5, in <module>     in v: typeerror: 'swigpyobject' object not iterable 

any suggestions?

you might want try boost.python , py++. if using boost provides nice wrapping (and pretty automatic wrapping) of complex c++ constructs. have used in several projects.

also should take @ this question looks related not issue.
