All,
I'm currently exposing much of our C++ API to Python and have had much success
with everything up to here. I'm running into issues trying to expose a pointer
to a vector which holds pointers to instances of a class.
The question is: is there more I have to do to export a pointer to a vector of
a class type we've defined? Or is there something simpler that I'm not seeing?
I've tried exposing a pointer to a vector, but that didn't turn out well. I
was getting value_type undefined errors and could not find any postings on them.
Perhaps that way was correct but I didn't not have the whole piece in place.
Thanks in advance!
CODE: (all of my code and sample types replace our actual data types)
-------------------------------------------------------------------------
C++
-------
class sample {
public:
std::vector<Derived*> *vec;
};
class_<std::vector<Derived *> >("std_vector_Derived")
.def(vector_indexing_suite<vector<Derived *>())
;
class_<sample>("sample")
.def_readwrite("vec", &sample::vec)
;
Python
--------
inst = EXPOSED_MODULE.EXPOSED_FUNCT( )
#EXPOSED_MODULE/FUNCT are replacements for the real name...
#inst is an instance of "sample" returned from a exposed c++ function after it
was populated it with data.
print inst.vec[0]
#Assume vector was populated from C++ side and verified to be populated in C++.
#Problem occurs here because of type...
STDERR (PYTHON)
---------------
TypeError: No to_python(by-value) converter found for C++ type: class
std::vector<class Derived*, class std::allocator<class Derived*> > *
