CircularKernel::CompareYatX_2 Concept Reference
Geometric Concepts

## Definition

A function object concept to compare a point `p` and an arc `a` on the vertical line passing through `p`.

## Operations
A model of this concept must provide:
Comparison_result | operator() (const CircularKernel::Circular_arc_point_2 &p, const CircularKernel::Circular_arc_2 &a)
| For a circular arc. More...
Comparison_result | operator() (const CircularKernel::Circular_arc_point_2 &p, const CircularKernel::Line_arc_2 &a)
| Same for a segment.

## Member Function Documentation

Comparison_result CircularKernel::CompareYatX_2::operator() | ( | const CircularKernel::Circular_arc_point_2 & | p,
|  | const CircularKernel::Circular_arc_2 & | a
| ) |  |

For a circular arc.

Precondition
  The arc `a` must be monotone and `p` must be in the vertical range of `a`.
