Stream Iterator (CGAL_Istream_iterator)

Definition

#include <CGAL/IO/Istream_iterator.h>

Creation

CGAL_Istream_iterator<T,Stream> i;
	creates an end-of-stream iterator i. This is a past-the-end iterator, and it is useful when constructing a range.
CGAL_Istream_iterator<T,Stream> i ( Stream& s);
	creates an input iterator i reading from $s$. When $s$ reaches end of stream, this iterator will compare equal to an end-of-stream iterator created using the default constructor.

Operations

Example

#include <CGAL/Cartesian.h>
#include <CGAL/Point_2.h>
#include <CGAL/IO/Istream_iterator.h>
#include <CGAL/IO/Window_stream.h>
#include <iostream.h>
#include <algo.h>

typedef CGAL_Point_2< CGAL_Cartesian< double > >           Point;
typedef CGAL_Istream_iterator< Point, CGAL_Window_stream>  Iterator;

int main () {
    CGAL_Window_stream window( 512, 512);
    window.init( -1.0, 1.0, -1.0);
    copy( Iterator(window), Iterator(), ostream_iterator<Point>(cout,"\n"));
    return 0;
}
