Returns a new polygon geometry corresponding to a segmentized approximation
of the curve.

    virtual void setExteriorRing( QgsCurve *ring /Transfer/ );
%Docstring
Sets the exterior ring of the polygon. The CurvePolygon type will be updated to match the dimensionality
of the exterior ring. For instance, setting a 2D exterior ring on a 3D CurvePolygon will drop the z dimension
from the CurvePolygon and all interior rings.

:param ring: new exterior ring. Ownership is transferred to the CurvePolygon.

Adds an interior ring to the geometry (takes ownership)

%Docstring
Removes an interior ring from the polygon. The first interior ring has index 0.
The corresponding ring is removed from the polygon and deleted. If a ring was successfully removed
the function will return true.  It is not possible to remove the exterior ring using this method.

.. seealso:: :py:func:`removeInteriorRings`

    void removeInteriorRings( double minimumAllowedArea = -1 );
%Docstring
Removes the interior rings from the polygon. If the minimumAllowedArea
parameter is specified then only rings smaller than this minimum
area will be removed.
