STL-pair-like triplet class - do I roll my own?
c++, std, stdtuple, triplet
Solution
No, don't roll your own. Instead, take a look at `std::tuple` - it's a generalization of `std::pair`. So here's a value-initialized triple of `int`s:
std::tuple<int, int, int> triple;
If you want, you can have a type alias for triples only:
template<typename T1, typename T2, typename T3>
using triple = std::tuple<T1, T2, T3>;
Problem
I want to use a triplet class, as similar as possible to std::pair. STL doesn't seem to have one. I don't want to use something too heavy, like Boost. Is there some useful FOSS non-restrictive-license triplet class I could lift from somewhere? Should I roll my own? Should I do something else entirely? Edit: About `std::tuple`... Is there really no benefit to a triplet-specific class? I mean, with tuple, I can't do ``` template<typename T1, typename T2, typename T3> std::tuple<T1, T2, T3> triple; ``` now can I? Won't I have to typedef individual-type-combination triples?
