All points will be removed from the collection or collections making up the geometry. In most cases this is equivalent to the .clear() method of a std::vector<...>. In the case of a polygon, this clear functionality is automatically called for the exterior ring, and for the interior ring collection. In the case of a point, boxes and segments, nothing will happen. 23 24[heading Synopsis] 25``template<typename Geometry> 26void clear(Geometry & geometry)`` 27 28[heading Parameters] 29 30[table 31[[Type] [Concept] [Name] [Description] ] 32[[Geometry &] [Any type fulfilling a Geometry Concept ] [geometry] [A model of the specified concept which will be cleared ]] 33] 34 35 36[heading Header] 37Either 38 39`#include <boost/geometry.hpp>` 40 41 42Or 43 44`#include <boost/geometry/algorithms/clear.hpp>` 45 46[include reference/algorithms/clear.qbk] 47 48 49[endsect] 50 51
