Use of overloaded function inside template with template param

Question

Can it be done in a nice way?

template <class T> Init(T &object, Type type)
{
    Collider collider;
    switch (type)
    {
    case TypeA:
        collider.InitAsA(object);
        break;
    case TypeB:
        collider.InitAsB(object);
    }
}

call with

A a;
Init(a, TypeA);
B b;
Init(b, TypeB);

A and B have no common ancestor.

void Collider::InitAsA(A &a);
void Collider::InitAsB(B &b);

EDIT:

Collider::InitAs.. can't be changed into template, and can't be changed at all, for reason i can't change others code.

Type can be int, actually it is an enum.

With your Init() function, you can just use function overloading:

void Init(A &object)
{
    Collider collider;
    collider.InitAsA(object);
}

void Init(B &object)
{
    Collider collider;
    collider.InitAsB(object);
}

However, you could just overload the Init() method:

void Collider::Init(A &a);
void Collider::Init(B &b);

And then, if you still want a template function, it could look like this:

template <typename T>
void Init (T &object)
{
    Collider collider;
    collider.Init(object);
}
