Detailed Description

template<typename Point, typename PointOfSegment = Point, typename SideStrategy = typename strategy::side::services::default_strategy < typename cs_tag<Point>::type >::type, typename CalculationType = void>
class boost::geometry::strategy::within::winding< Point, PointOfSegment, SideStrategy, CalculationType >

Within detection using winding rule.

Template Parameters

Point	Any type fulfilling a Point Concept
PointOfSegment	segment point type
SideStrategy	Side strategy
CalculationType	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

Note

The implementation is inspired by terralib http://www.terralib.org (LGPL)

but totally revised afterwards, especially for cases on segments

Only dependant on "side", -> agnostic, suitable for spherical/latlong
