Kernel::AreParallel_2 Concept Reference
Kernel Function Object Concepts

## Definition

Refines:
  `AdaptableFunctor` (with two arguments)

See Also
  `CGAL::parallel()`

## Operations

A model of this concept must provide:
bool | operator() (const Kernel::Line_2 &l1, const Kernel::Line_2 &l2)
| returns `true`, if `l1` and `l2` are parallel or if one of those (or both) is degenerate.
bool | operator() (const Kernel::Ray_2 &r1, const Kernel::Ray_2 &r2)
| returns `true`, if `r1` and `r2` are parallel or if one of those (or both) is degenerate.
bool | operator() (const Kernel::Segment_2 &s1, const Kernel::Segment_2 &s2)
| returns `true`, if `s1` and `s2` are parallel or if one of those (or both) is degenerate.
