## Definition

Refines
  `AdaptableBinaryFunction`

See also
  `CGAL::compare_xyz()`

## Operations
A model of this concept must provide:
Comparison_result | operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q)
| Compares the Cartesian coordinates of points `p` and `q` lexicographically in \( xyz\) order: first \( x\)-coordinates are compared, if they are equal, \( y\)-coordinates are compared.

## Member Function Documentation

## ◆ operator()()

Comparison_result Kernel::CompareXYZ_3::operator() | ( | const Kernel::Point_3 & | p,
|  | const Kernel::Point_3 & | q
| ) |  |

Compares the Cartesian coordinates of points `p` and `q` lexicographically in \( xyz\) order: first \( x\)-coordinates are compared, if they are equal, \( y\)-coordinates are compared.

If they are equal, \( z\)-coordinates are compared.
