#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.
