CGAL::Env_surface_data_traits_3< Traits, XyData, SData, Cnv >::Xy_monotone_surface_3 Class Reference

`#include <CGAL/Env_surface_data_traits_3.h>`

## Inherits from

Base_xy_monotone_surface_3.

## Definition

The `Xy_monotone_surface_3` class nested within the surface-data traits extends the `Base_traits_3::Xy_monotone_surface_3` type with an extra data field.

## Creation

| Xy_monotone_surface_3 ()
| default constructor.
| Xy_monotone_surface_3 (const Base_xy_monotone_surface_3 &base)
| constructs an \( xy\)-monotone surface from the given `base` surface with uninitialized data field.
| Xy_monotone_surface_3 (const Base_xy_monotone_surface_3 &base, const Xy_monotone_surface_data &data)
| constructs an \( x\)-monotone surface from the given `base` \( x\)-monotone surface with an attached `data` field.

## Access Functions

const Xy_monotone_surface_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 Xy_monotone_surface_data &data)
| sets the data field.
