We have a lot of C++ code using a home-grown Event<T> class template. An
Event<T> is just a list of pointers to callback function objects. More
precisely, an Event<T> is a std::list<unary_function<T>*>, where
unary_function is a polymorphic function object class. Code that
generates an event iterates through the list, dereferences each pointer
and calls the corresponding function.
I'd like python code to be able to generate these C++ events. To do that
Event<>s need to support Python's iterable interface, which requires
random access to the container. Unfortunately, std::list<> doesn't
support random access. Short of copying the contents of every
std::list<> to a std::vector<> for Python's benefit I don't see how this
can be accomplished.
Does anyone have any ideas for a simpler, more natural implementation?
