|void||setOuterBoundary (KmlLinearRing outerBoundary)|
A Polygon is defined by an outer boundary and 0 or more inner boundaries. The boundaries, in turn, are defined by LinearRings. When a Polygon is extruded, its boundaries are connected to the ground to form additional polygons, which gives the appearance of a building or a box. Extruded Polygons use PolyStyle for their color, color mode, and fill.
