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 between p and r. More...
 

Member Function Documentation

bool Kernel::AreOrderedAlongLine_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 between p and r.

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