Detailed Description

template<class T>
class OFSetIterator< T >

This template class represents an iterator class for corresponding set data structures in ofstd.

Note the following properties of this class:

• even if the underlying set is unordered, it does have an internal order which can be used for iteration purposes
• a reference to the set which shall be iterated over will be remembered inside an object of OFSetIterator<T>; the set will NOT be copied
• it is possible to iterate from beginning to end or from end to beginning of the underlying set using Next() or Prev() (see below)
• if an element from the set is removed during the iteration, the iteration process has to be cancelled and restarted
• two OFSetIterators can be compared through operators == and !=; two iterators are considered to be identical, if and only if they operate on the exact same set (identical memory addresses) and they currently refer to the same element
