Kernel::AreStrictlyOrderedAlongLine_2 Concept Reference
Kernel Function Object Concepts

## Definition

Refines:
  `AdaptableFunctor` (with three arguments)

See Also
  `CGAL::are_strictly_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 the three points are collinear and `q` lies strictly between `p` and `r`. More...

## Member Function Documentation

bool Kernel::AreStrictlyOrderedAlongLine_2::operator() | ( | const Kernel::Point_2 & | p,
|  | const Kernel::Point_2 & | q,
|  | const Kernel::Point_2 & | r
| ) |  |

returns `true`, iff the three points are collinear and `q` lies strictly between `p` and `r`.

Note that `false` is returned, if `q==p` or `q==r`.
