Operations

A model of this concept must provide:

bool operator() (const Kernel::Circle_2 &c, const Kernel::Point_2 &p)
 returns true iff p lies on the negative side of c. More...
 
bool operator() (const Kernel::Line_2 &l, const Kernel::Point_2 &p)
 returns true iff p lies on the negative side of l (l is considered a half-space). More...
 
bool operator() (const Kernel::Triangle_2 &t, const Kernel::Point_2 &p)
 returns true iff p lies on the negative side of t. More...
