CGAL::Join_input_iterator_3< I1, I2, I2, Op > Class Template Reference

#include <CGAL/iterator.h>

Definition

template<typename I1, typename I2, typename I2, typename Op>
class CGAL::Join_input_iterator_3< I1, I2, I2, Op >

The class Join_input_iterator_3 joins three iterators. The result is again an iterator (of the same iterator category type as the original iterator) that reads an object from the stream and applies a function object to that object.

Is Model Of:

InputIterator
