Detailed Description

template<bool Reverse, typename Point, typename PointOfSegment = Point, typename CalculationType = void>
class boost::geometry::strategy::within::oriented_winding< Reverse, Point, PointOfSegment, CalculationType >

Within detection using winding rule, but checking if enclosing ring is counter clockwise and, if so, reverses the result.

Template Parameters

Point
Reverse	True if parameter should be reversed
PointOfSegment
CalculationType

Author

Barend Gehrels

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
