rescue::polygonal_curve Template Class Reference

This class provides basic functionality for polygonal curves, such as appending points, removing points, file-IO and iterators, as well as expressing the action of a transformation group acting on the curve. More...

Detailed Description

template<class point> template class rescue::polygonal_curve

This class provides basic functionality for polygonal curves, such as appending points, removing points, file-IO and iterators, as well as expressing the action of a transformation group acting on the curve.

Constructor & Destructor Documentation

template<classpoint>
rescue::polygonal_curve< point >::polygonal_curve<point> ( )
 

Standard-Konstruktor, welcher einen leeren Polygonzug erzeugt.

Dieser kann durch push_front() -Aufrufe zu einem nicht-leeren Polygonzug erweitert werden.

template<classpoint>
rescue::polygonal_curve< point >::polygonal_curve<point> ( const polygonal_curve< point >& P )
 

Copy-Construcotr for a polygonal curve.

All vertices in the returned curve are newly instantiated.

Member Function Documentation

template<classpoint>
polygonal_curve< point >& rescue::polygonal_curve< point >::operator= ( const polygonal_curve< point >& P )
 

Copy-Construcotr for a polygonal curve.

All vertices in the returned curve are newly instantiated.
