Class that represents an iterator pointing to a single element in the IndexSet as returned by IndexSet::begin().
Definition at line 712 of file index_set.h.
using IndexSet::ElementIterator::iterator_category = std::forward_iterator_tag |
Mark the class as forward iterator and declare some alias which are standard for iterators and are used by algorithms to enquire about the specifics of the iterators they work on.

inline |
Return the distance between the current iterator and the argument. In the expression it_left-it_right
the distance is given by how many times one has to apply operator++ to the right operand it_right
to get the left operand it_left
(for a positive return value), or to it_left
to get the it_right
(for a negative return value).
