Writing a template that can use a std::vector or a std::set
c++, templates
Solution
How about the `insert(iterator, value_type)` overload and calling it with `end()`? It's available in both and should do what you want! Works on `std::list` as well!
There's really no need for type-dispatching here.
Problem
I've written an asynchronous job queue class which has been working nicely for ages. It uses a `std::vector` as the underlying collection to keep jobs in and then processes them later as you might expect. When I add a job it does a `push_back` on this `vector`. Recently I decided that I wanted to templatize the underlying collection type that it uses and the with way I've written it, this should be very simple. It's now declared thus: ``` template<typename J, typename CollectionT = std::vector<J>> class async_jobqueue { public: ``` There's just one snag, for vectorish type containers I want to push things onto the end of the collection and call `push_back`, for settish type containers I'll want to call `insert`. How can I make a compile decision about which to call? Or is there a handy adapter I can use?
