CGAL::Arr_curve_data_traits_2< Tr, XData, Mrg, CData, Cnv >::X_monotone_curve_2 Class Reference

`#include <CGAL/Arr_curve_data_traits_2.h>`

## Inherits from

Base_x_monotone_curve_2.

## Definition

The `X_monotone_curve_2` class nested within the curve-data traits extends the `Base_traits_2::X_monotone_curve_2` type with an extra data field.

## Creation

| X_monotone_curve_2 ()
| default constructor.
| X_monotone_curve_2 (const Base_x_monotone_curve_2 &base)
| constructs an \( x\)-monotone curve from the given `base` curve with uninitialized data field.
| X_monotone_curve_2 (const Base_x_monotone_curve_2 &base, const X_monotone_curve_data &data)
| constructs an \( x\)-monotone curve from the given `base` \( x\)-monotone curve with an attached `data` field.

## Access Functions

const X_monotone_curve_data & | data () const
| returns the field (a non-const version, which returns a reference to the data object, is also available).
void | set_data (const X_monotone_curve_data &data)
| sets the data field.
