TTGeoJSONPolygon

@interface TTGeoJSONPolygon : TTGeoJSONObject

A Geometry type comprising one or more LineStrings. The exterior ring represents the outer edges of a polygon and is a LineStrings of at least four Positions in counterclockwise order. The interior rings (0 or more) - LineStrings of at least four Positions in clockwise order - define holes in the polygon. In all cases the first and the last position in a LineString contain identical values.


                    
                    
                    -initWithExteriorRing:withInteriorRings:withBoundingBox:

Creates an instance of Polygon without a bounding box, with provided exterior ring and insterior rings.

Declaration

Objective-C

- (instancetype _Nonnull)
    initWithExteriorRing:(TTGeoJSONLineString *_Nonnull)exteriorRing
       withInteriorRings:(NSArray<TTGeoJSONLineString *> *_Nonnull)interiorRings
         withBoundingBox:(TTBoundingBox *_Nullable)boundingBox;

Swift

init(exteriorRing: TTGeoJSONLineString, withInteriorRings interiorRings: [TTGeoJSONLineString], with boundingBox: TTBoundingBox?)

Parameters

`boundingBox`	a bounding box encompassing this Polygon
`exteriorRing`	the exterior ring, definiting the outline of this Polygon
`interiorRings`	a collection of interior rings, defining the holes in this Polygon

Return Value

TTGeoJSONPolygon
