## Operations
A model of this concept must provide the following operations. For each of them, it returns `true` iff `x` and `y` are equal.
bool | operator() (const Kernel::Point_2 &x, const Kernel::Point_2 &y)
bool | operator() (const Kernel::Vector_2 &x, const Kernel::Vector_2 &y)
bool | operator() (const Kernel::Direction_2 &x, const Kernel::Direction_2 &y)
bool | operator() (const Kernel::Line_2 &x, const Kernel::Line_2 &y)
bool | operator() (const Kernel::Ray_2 &x, const Kernel::Ray_2 &y)
bool | operator() (const Kernel::Segment_2 &x, const Kernel::Segment_2 &y)
bool | operator() (const Kernel::Circle_2 &x, const Kernel::Circle_2 &y)
bool | operator() (const Kernel::Triangle_2 &x, const Kernel::Triangle_2 &y)
bool | operator() (const Kernel::Iso_rectangle_2 &x, const Kernel::Iso_rectangle_2 &y)
