In C++ it is possible to determine whether there exists a member of a class of a specified type (including member functions) with a given name. As far as I know, there exists no such functionality in Boost. Why is this? It can easily be implemented as a traits class for a specific identifier/signature, which can then be made into a macro.

Sounds like BOOST_MPL_HAS_XXX_TRAIT_DEF : http://www.boost.org/doc/libs/1_36_0/libs/mpl/doc/refmanual/has-xxx-trait-de... HTH, ~ Scott

No, because that only detects member typedefs. It is possible to detect members of any type, for instance, whether there exists an int T.foo. Sean

Boost.MPL provides such a macro, although I believe it only detects nested types at the moment. Sebastian

Well, it wasn't made because it was'nt made *pouts* There is a starting for this that have been satrted like today by Daniel Walker and myself.

Ah. I apologize. I had assumed that it was so simple that it would have to be in Boost, thus there would be some rationale for it not being. However, it looks like Joel Falcou has whipped something up while I complained about it, so props to him. Sean

Hi, I'm not sure if it is exactly what you're looking for, but you can also take a look at the Mirror reflection library. You can find the most recent version in the boost sandbox svn repository at: http://svn.boost.org/svn/boost/sandbox/mirror/ a more stable version in the vault: http://www.boostpro.com/vault/ -- ________________ ::matus_chochlik

Is it planned to get it into review for acceptance/or not ? It looks quite interesting. -- Alp Mestan --- http://blog.mestan.fr/ --- http://alp.developpez.com/ --- In charge of the Qt, Algorithms and Artificial Intelligence sections on Developpez

Yep, the plan is to ask for a review when several minor things get fixed and the docs are finished. But currently I have some other projects that need a lot of attention, so I had to put Mirror on hold for a while. I'm hoping to have it review ready by the end of this year.
It looks quite interesting. Thanks ;)
