How to extend a templated c++ class in python with SWIG to allow the [] operator

Question

I have a templated c++ array class which uses the standard vector class:

#include 
#include 

using namespace std;

template

        

Answer 1

To provide a more generic solution:

%define ArrayExtendVal(name, T) %extend name { T getitem(int i) { return (*self)[i]; } } %enddef %define ArrayExtendRef(name, T) %extend name { T& getitem(int i) { return (*self)[i]; } } %enddef %define ArrayExtendConstRef(name, T) %extend name { const T& getitem(int i) { return (*self)[i]; } } %enddef ... %ignore myNamespace::myClass::operator[] %include "my_class.h" ArrayExtendVal(myClass, double); ArrayExtendRef(myClass, double); ArrayExtendConstRef(myClass, double);

Note the %ignore directive that is missing in the other answers.
