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

#include <CGAL/iterator.h>

Definition

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

Public Types
typedef Op::result_type	value_type
typedef std::iterator_traits< I1 >::difference_type	difference_type
typedef value_type *	pointer
typedef value_type &	reference

Public Member Functions
I1	current_iterator1 () const
	returns current position of the first iterator.
I2	current_iterator2 () const
	returns current position of the second iterator.
I3	current_iterator3 () const
	returns current position of the second iterator.
const value_type &	operator* () const
	returns op(current_iterator1(), current_iterator2(), current_iterator3()).

Creation
	Join_input_iterator_3 ()
	Default constructor.
	Join_input_iterator_3 (I1 i1, I2 i2, I3 i3, const Op &op=Op())
	creates a join iterator from the given iterators i1, i2, i3, and the functor op.
