Evening all,
I'd like to copy the contents of a boost::mpl::vector_c (or similar) into an output iterator at runtime. I've not found a clean way to get an MPL sequence into a runtime-usable form. So far, I've gotten the included ugliness to work.
0) Is there some simple, idiomatic way to accomplish this goal that I've missed? 1) Any suggestions for how to clean this up? Specifically ways to reduce the assumptions about the underlying MPL sequence or fixes for braindead mistakes I've made? 2) Is there some way to have syntax like 'seqcopy<S>(iter)' where the iterator type is deduced but the sequence type is explicit?
Thanks, Rhys
Good morning, 0) the "only" run-time stuff in the MPL is mpl::for_each. 1) See attached, I guess this could be considered a bit cleaner. 2) Probably easiest by writing a function that does the type deduction for you. But ... Perhaps Boost.Fusion is what you are looking for? Hope this helps, Cheers, Rutger
