CGAL::Arr_polycurve_traits_2< SubcurveTraits_2 >::Construct_curve_2 Class Reference

`#include <CGAL/Arr_polycurve_traits_2.h>`

## Definition

template<typename SubcurveTraits_2>
class CGAL::Arr_polycurve_traits_2< SubcurveTraits_2 >::Construct_curve_2

Construction functor of a general (not necessarily \(x\)-monotone) polycurve.

This functor constructs general polycurve. Its `operator()` is oveloaded to support various input types.

Note that the composing subcurves, depending on the `SubcurveTraits_2`, might not be \(x\)-monotone.

## Operations
Curve_2 | operator() (const Subcurve_2 &subcurve) const
| Obtain a polycurve that comprises of one given subcurve.
template<typename ForwardIterator >
Curve_2 | operator() (ForwardIterator begin, ForwardIterator end) const
| Construct a well-oriented polycurve from a range of either `SubcurveTraits_2::Point_2` or `SubcurveTraits_2::Curve_2`.

## Member Function Documentation

## ◆ operator()() [1/2]

template<typename SubcurveTraits_2 >

Curve_2 CGAL::Arr_polycurve_traits_2< SubcurveTraits_2 >::Construct_curve_2::operator() | ( | const Subcurve_2 & | subcurve | ) | const

Obtain a polycurve that comprises of one given subcurve.

Parameters

  subcurve | input subcurve.

Precondition
  `subcurve` is not degenerated (not tested).

Returns
  A polycurve with one subcurve, namely `subcurve`.

## ◆ operator()() [2/2]

template<typename SubcurveTraits_2 >
template<typename ForwardIterator >

Curve_2 CGAL::Arr_polycurve_traits_2< SubcurveTraits_2 >::Construct_curve_2::operator() | ( | ForwardIterator | begin,
|  | ForwardIterator | end
| ) |  | const

Construct a well-oriented polycurve from a range of either `SubcurveTraits_2::Point_2` or `SubcurveTraits_2::Curve_2`.

Parameters

  begin | iterator pointing to the first element in the range.
  end | iterator pointing to the past-the-end element in the range.

Precondition
  The given range form a continuous and well-oriented polycurve (not tested).
  Contains no degenerated subcurves (not tested)

Returns
  A polycurve using the corresponding construction implementation.
