Metafunction defining [*type] as the ring_type of the \3.

A polygon contains one exterior ring and zero or more interior rings (holes). This metafunction retrieves the type of the rings. Exterior ring and each of the interior rings all have the same ring_type. Geometry

A type fullfilling the Ring, Polygon or MultiPolygon concept.
