Hi list,

how can I detect if a class inherits from a generic class? E.g.,

template <class Derived> class base {};

class final: public base<final> {};

is_instance_of from lambda library is what you want (see boost/lambda/detail/is_instance_of.hpp). It's not part of public interface though, so either copy it to your location or use on your own risk. Roman Perepelitsa.

thanks for the pointer, that's exactly it. However, I think I will end up deriving the base class from a non-templated tag class and use is_base_of instead - I do not think I'd be able to maintain my own version is_instance_of should it be changed/removed. Cheers, Francesco.
