a vector of different class

[ilyes]

hi
i have a base class and many other class that i have derived from this class

class Base{};
class Deri1: public Base{};// with private methode and attribut
class Deri2: public Base{};// with private methode and attribut
..
..

now i am parsing a buffer and so instanciate one of this class and stok it in a vector<Base*> myvector;
i relosve that with the cast
and after that, when i would like to do
myvector[i]->methodeofDeri1();//this methode is public
i will generate an error
error: class Base had no member call methodeofDeri1();

what can i do to resolve this problem?

thinks,

[Bazzy]

Put a virtual method in Base class called methodeofDeri1, then override it in the derived classes

[ilyes]

so,
i have many derived class with many methodes that i can't put them as virtual in the base class!

Virtual functions are definately the way to go when you can. If that's not an option you can fall back to dynamic_cast
