Hi,

Don't suppose there is anything that can be used to help guide template construction. For example:

Thanks,
Uni
template<typename TName>
class C{
      if TName==X
            int function();
      else
            TName function();
      end if
};

It seems that you are thinking of template specialization here, see http://www.cprogramming.com/tutorial/template_specialization.html for more. Otherwise, you are right, there is no such thing with templates.

Also, besides what jkr said, to reuse common template code in a conditional manner (albeit at pre-processor time) you can use old-fashioned # preprocessor directives and include in separate files with/without a given #define.

It may be a little messy and I don't do it personally, I prefer the templates to be clean (as possible).
