The first index, 0, will always return the exterior ring. Indices > 0 will return the interior ring at the given index (e.g., poly[1] and poly[2] would return the first and second interior ring, respectively). CAREFUL: Internal/External are not the same as Interior/Exterior! Return a pointer from the existing geometries for use internally by the object's methods. _get_single_external() returns a clone of the same geometry for use by external code. rr N)r*Z get_extringr3Z get_intringrindexr r r_get_single_internalzs  zPolygon._get_single_internalcCstt|||jdS)N)r:)rr*r2r>r:r<r r r_get_single_externalszPolygon._get_single_externalcCs t|jS)z$Return the number of interior rings.)r*Z get_nringsr3rr r rrszPolygon.num_interior_ringscCs|dS)z%Get the exterior ring of the Polygon.rr rr r r _get_ext_ringszPolygon._get_ext_ringcCs ||d<dS)z%Set the exterior ring of the Polygon.rNr )rr9r r r _set_ext_ringszPolygon._set_ext_ringcstfddttDS)z,Get the tuple for each ring in this Polygon.c3s|]}|jVqdSr1)rr'rrr r sz Polygon.tuple..)rrrrr rrrsz Polygon.tuplecs0dfddtjD}ddj|fS)z.Return the KML representation of this Polygon.c3s |]}d|djVqdS)z%%sr N)kmlrBrr rrCszPolygon.kml..z:%s%sr)joinrrrE)rZ inner_kmlr rrrEsz Polygon.kml)r5)__name__ __module__ __qualname__Z _minlengthr rr classmethodr%r r&r,r;r>r?rZ_set_single_rebuildZ _set_singleZ_assign_extended_slice_rebuildZ_assign_extended_slicepropertyrr@rAZ exterior_ringr0rZcoordsrE __classcell__r r rrr s4 %      rN) ctypesrrZdjango.contrib.gis.geosrr*Z django.contrib.gis.geos.geometryrZdjango.contrib.gis.geos.libgeosrZ"django.contrib.gis.geos.linestringrrr r r rs
