## Definition

Refines
  `AdaptableTernaryFunction`

See also
  `CGAL::collinear_are_ordered_along_line()`

## Operations
A model of this concept must provide:
bool | operator() (const Kernel::Point_2 &p, const Kernel::Point_2 &q, const Kernel::Point_2 &r)
| returns `true`, iff `q` lies between `p` and `r`.

## Member Function Documentation

## ◆ operator()()

bool Kernel::CollinearAreOrderedAlongLine_2::operator() | ( | const Kernel::Point_2 & | p,
|  | const Kernel::Point_2 & | q,
|  | const Kernel::Point_2 & | r
| ) |  |

returns `true`, iff `q` lies between `p` and `r`.

Precondition
  `p, q` and `r` are collinear.
