container to store multiple types

container to store multiple types

container to store multiple types

Is there a way I could store multiple objects of different types in a container, say, a vector or map or an array?

template <class T>
class Holder
        T * m_ptr;
        Holder(T * ptr)
            m_ptr = ptr;

class Cls1

class Cls2

class Cls3

int main()
    Cls1 ptr1 = new Cls1;
    Cls2 ptr2 = new Cls2;
    Cls3 ptr3 = new Cls3;

    Holder<Cls1> hobj1(ptr1);
    Holder<Cls2> hobj2(ptr2);
    Holder<Cls3> hobj3(ptr3);

    //How to store the holder objects hobj1, hobj2, hobj3
    // in a STL container or array?

RE: container to store multiple types

I understand there is boost::any
Apart from this, is there any workaround possible with C++ standard libraries itself?

RE: container to store multiple types

Derive them from the same empty base class
