Range and value iterators
[Common functionality]
Detailed Description
Both range and value iterators have a rather simple interface for controlling iteration (which deviates from what you might be used to from other iterators).
The application operator (if i
is an iterator, it is invoked by i()
) tests whether an iterator has not yet reached its end (in this case, true
is returned). The prefix increment operator (if i
is an iterator, this is invoked as ++i
) moves the iterator to the next element (either next value or next range).
Value iterators provide access to the value by the member function val()
. Range iterators provide access to the smallest, largest, and width of the current range by min()
, max()
, and width()
respectively.
