Good morning, First of all, thank you very much for your help in advance. I have a problem in dynamic casting. sc_object *o = (sc_object*)(x[i]); if (typeid(*o)==typeid(sc_out<bool>)) sc_out<bool> *thisPort=dynamic_cast(o); sc_out<T> type is a polymorphic template class that inherits sc_object class. I would like to cast the polymorphic object (*o) without to know the template type T of sc_out<T>. I would avoid all the possible casts that can result in an enormous computational burden. I would like to access to the methods of sc_out<T> type.I cannot modify the code of sc_out<T> and sc_object.Does exist any way to perform this "blind" operation? Does exist a boost library that allows the use of the string typeid.name() as type in dynamic cast operation? thank you very much in advance Lorenzo PIERALISI
