Function that takes an STL iterator over ANY container of a elements of a specific type

Question

How would I define a function that takes as input an iterator over any type of STL container, but only to those of a specific templated type. For example:

Any iterator o

Answer 1

You only want to iterate over containers of my_special_type? In that case:

template 
struct enable_if;

template 
struct enable_if
{
    typedef T type;
};

template 
struct is_same
{
    enum {value = false};
};

template 
struct is_same
{
    enum {value = true};
};

template 
typename enable_if::value,
                  void>::type
function(Iter begin, Iter end)
{
    // ...
}
