You can inline virtual functions just like any others: either by using the 'inline' keyword, or just by writing the function definition right into the declaration. Sometimes this makes sense (such as for destructors), sometimes it doesn't. It mostly depends on whether or not a compiler is able to decide what class a particular object pointer actually points to. Somtimes this can only be detemined at runtime and in that case, obviously, no inlining will occur.

More information and examples can be found on the web, e. g. here: http://msdn.microsoft.com/en-us/magazine/cc301407.aspx[^] or here: http://drdobbs.com/cpp/184403747[^]

In short - if the type of an object pointer can only be determined at runtime, then inlining is not possible, even if the base class and all derived classes do have inlined implementations of that function. If you really, absolutely, desperately need a function to be inlined, either make sure that a particular version is being called (if that is even possible), or simply don't use inheritance for that. That said, since inlining is really only the very last step in performance optimization, it's usally not a real issue: if you can't inline, then you just don't.
