C++ (Cpp) addLineString Examples

Example #1

File: OffsetCurveSetBuilder.cpp Project: asapnet/geos

/*private*/
void
OffsetCurveSetBuilder::add(const Geometry& g)
{
	if (g.isEmpty()) return;

	const Polygon *poly = dynamic_cast<const Polygon *>(&g);

	}

	const Point *point = dynamic_cast<const Point *>(&g);

		return;
	}

	const GeometryCollection *collection = dynamic_cast<const GeometryCollection *>(&g);

		return;
	}

	std::string out=typeid(g).name();
	throw util::UnsupportedOperationException("GeometryGraph::add(Geometry &): unknown geometry type: "+out);

Example #2

	// LineString also handles LinearRings
