Description
SetEmpty returns the Geometry to its original initialization state by releasing all data referenced by the Geometry.
Remarks
Use the SetEmpty method to clear geometries and release memory. For example, a polygon with 100 rings will have an internal array of 100 pointers to ring objects. That array will go away and Release will be called on each ring. If that polygon had the only reference on those rings, then they'll go away, which releases all their segments, which may also then go away.
