Operations

A model of this concept must provide:

Kernel::Vector_2 operator() (const Kernel::Point_2 &a, const Kernel::Point_2 &b)
 introduces the vector b-a.
 
Kernel::Vector_2 operator() (const Origin &o, const Kernel::Point_2 &b)
 introduces the vector b.
 
Kernel::Vector_2 operator() (const Kernel::Point_2 &a, const Origin &o)
 introduces the vector -a.
 
Kernel::Vector_2 operator() (const Kernel::Segment_2 &s)
 introduces the vector s.target()-s.source().
 
Kernel::Vector_2 operator() (const Kernel::Ray_2 &r)
 introduces a vector having the same direction as r.
 
Kernel::Vector_2 operator() (const Kernel::Line_2 &l)
 introduces a vector having the same direction as l.
 
Kernel::Vector_2 operator() (const Null_vector &NULL_VECTOR)
 introduces a null vector .
