iterator_adaptor const iterator question

I have now built a couple of iterators using boost::iterator_adaptor.
These are not adapted iterators but rather iterators developed to iterate
over interfaces that have not iterators.

I havent found a good example of how to declare the equivalent of a
const_iterator like in vector. What would the declartion look like?

If the definition of an iterator is:

typedef boost::iterator_adaptor< Base, Policy > iterator;

What would the declartion for a const_iterator look like?

Thanks for the help.
