How to iterate over a container that has no begin/end?

Question

(C++98, gcc4.4.7) Let's say I have a database-connected container that does not provide iterators over itself, but only an indexed getter and size(), ex:

template<typename T>
class DbVector
{
public:
  const T& getValue(const size_t) const;
  size_t size() const;
};

I'd like to be able to use it in range-based algorithms. This sounds like a common problem. Does Boost provide a solution for this?

I've looked a bit into Boost.Iterator and Boost.Range, but with no success. I'm not even sure how my google query should be formulated to find anything useful.

I thought maybe there is a library, that would allow something like:

typedef Iterable<DbVector<int>,
                 &DbVector<int>::getValue,
                 &DbVector<int>::size>
        IterableDbVectorInt;

const DbVector<int>& dbVector = getDbVector();
return boost::any_of_equal(IterableDbVectorInt(dbVector), someValue);

I know I could write it myself from scratch, but I'm really trying not to reinvent the wheel.

Any boost-based ideas?
