Detailed Description

Map iterator.

The Map iterator is an abstract class which provides access to the elements of the map without having to copy them first. The constness of its methods refers actually to the constness of the Map it's attached to, not to the constness of the iterator itself: for instance, the 'set' methods are non-const because they change the map, even if they don't change the iterator state; conversely, the 'reset' method is const even if it does change the state of the iterator, but the map itself is untouched
