Hello Francesco,
Indeed, multi_index_container provides a nested value_type typedef that you can use exactly in the way you describe. Have you encountered any problem in doing so?
Hi Joaquin, funny thing, I used that syntax in the example but did not try it really in the code. Talk about intuitive interface :) The only thing I had to do was to add a "typename" before "T::" and everything seems to be ok now. Sorry about the noise, I'm quite a newbie C++ programmer and I could not find the answer in the headers.
Thank you for using Boost.MultiIndex,
_I_ am the one who should thank you :) I'm writing this astronomical program to manipulate Poisson series (which are to be ordered in different ways at the same time), and multiIndex really lifted a lot of weight from my shoulders. My only possible concern about multiIndex is how much widespread is its use in the C++ programming community. Knowing that there are many people adopting it would really make me feel safer, since I'm going to use it _very_ heavily in my software. Anyway, thanks very much, for multiIndex and your answer :) Francesco
