Within detection using winding rule. Side strategy used internally is choosen based on Point's coordinate system.
template<typename Point, typename PointOfSegment, typename CalculationType> class strategy::within::winding : public within::detail::winding_base_type::type< Point, PointOfSegment, CalculationType > { // ... };
| Parameter | Default | Description | 
|---|---|---|
| typename Point | Any type fulfilling a Point Concept | |
| typename PointOfSegment | Point | segment point type | 
| typename CalculationType | void | numeric type for calculation (e.g. high precision); if void then it is extracted automatically from the coordinate type and (if necessary) promoted to floating point |
