Re: [Boost-users] [tuple] How to manipulate the types

Adrián Etchevarne writes:

Problem:

How can I get a tuple type from a tuples::cons<> list ?

example:

given the type:

cons > >

obtain

tuple

Real problem:

I need to insert a type T at the beginning of a tuple, how I can do this?

example

given the type T and tuple, obtain a tuple

That's a lot easier to solve, in some sense, than the "Problem:" above. The cons list *is* a valid tuple. So to inserta new type at the front, just write const You might also want to look at http://spirit.sourceforge.net/dl_more/fusion_v2/libs/fusion/doc/html/index.h... which was recently accepted into Boost. -- Dave Abrahams Boost Consulting www.boost-consulting.com
