C++ Programming :: Determining if type T is a subclass of X


	Determining if type T is a subclass of X Hi, Is there a way using templates at compile time to determine if a type T is a subclass of another type? Basically I want to chose one struct if it is a subclass, or another struct if it is not. flopbucket wrote: > Is there a way using templates at compile time to determine if a type > T is a subclass of another type? > Basically I want to chose one struct if it is a subclass, or another > struct if it is not. Yes, IIRC. Check "is_derived_from" (or something like that) in Boost.

Yes there is, see boost::is_base_of http://www.boost.org/doc/html/boost_typetraits/reference.html#boost_t... - Sylvester On Jun 4, 10:27 am, Sylvester Hesp <s.hes@SPAMoisyn.nl> wrote: > flopbucket wrote : > > Hi, > > Is there a way using templates at compile time to determine if a type > > T is a subclass of another type? > > Basically I want to chose one struct if it is a subclass, or another > > struct if it is not. > Yes there is, see boost::is_base_of > http://www.boost.org/doc/html/boost_typetraits/reference.html#boost_t... > - Sylvester Is it possible to do this without using Boost library functions ???

Sure. Look at how Boost did it... do the same thing.

Look at "Modern C++ Design" - Alexandrescu The whole process is explained (and used in Loki).
