 If users perfer performance to correctness, method !GetFixPolygonVertexOrderAction will use table1. It guarantees that polygons in the target will have the correct vertex order if the target is enforced. If users perfer correctness to performance, method !GetFixPolygonVertexOrderAction will use table2. It guarantees that polygons in the target will have the correct vertex order if the vertex order rule of the target isn't none.
+
+Considering perfomrance, an additional paramether 'FdoBoolean checkInteriorRings' will be added for method FdoSpatialUtility::ReversePolygonVertexOrder(...). If users know the input polygon is a valid polygon, they can pass false for parameter checkInteriorRings to reverse its vertex order. Otherwise, pass true. Method FdoSpatialUtility::ReversePolygonVertexOrder(...) will check whether interior rings have the different vertex order with exterior ring and guarantee the returned polygon is a valid polygon after reversing the vertex order of the input polygon.
