Returns a Boolean value indicating whether two values are equal.
Equality is the inverse of inequality. For any values
aandb,a == bimplies thata != bisfalse.Declaration
Swift
static func == ( a : PolygonGeometry , b : PolygonGeometry ) -> Bool -
Hashes the essential components of this value by feeding them into the given hasher.
Implement this method to conform to the
Hashableprotocol. The components used for hashing must be the same as the components compared in your type’s==operator implementation. Callhasher.combine(_:)with each of these components.Important
In your implementation of
hash(into:), don’t callfinalize()on thehasherinstance provided, or replace it with a different instance. Doing so may become a compile-time error in the future.Declaration
Swift
func hash ( into hasher : inout Hasher ) -
The hash value.
Hash values are not guaranteed to be equal across different executions of your program. Do not save hash values to use during a future execution.
Important
hashValueis deprecated as aHashablerequirement. To conform toHashable, implement thehash(into:)requirement instead. The compiler provides an implementation forhashValuefor you.Declaration
Swift
var hashValue : Int { get } -
Creates a polygon geometry representing the whole earth with cut-outs for the inner paths.
Declaration
Swift
init ( innerPaths : [[ LatLngAltitude ]] = [])Parameters
innerPathsInner boundary of the polygon. A Polygon can contain multiple inner paths, which create multiple cut-outs inside the polygon.
-
Creates a polygon geometry with outer and inner boundaries.
If
pathis empty, this polygon geometry will cover the whole earth with cut-outs for the inner paths.Declaration
Swift
init ( path : [ LatLngAltitude ], innerPaths : [[ LatLngAltitude ]] = [])Parameters
pathOuter boundary of the polygon.
innerPathsInner boundary of the polygon. A Polygon can contain multiple inner paths, which create multiple cut-outs inside the polygon.
-
Inner boundary of the polygon. A Polygon can contain multiple inner paths, which create multiple cut-outs inside the polygon.
Declaration
Swift
let innerPaths : [[ LatLngAltitude ]] -
Outer boundary of the polygon.
Declaration
Swift
let path : [ LatLngAltitude ]
