PolygonGeometry

struct PolygonGeometry
 
extension PolygonGeometry : Equatable, Hashable

Represents the geometry definition for a polygon with an outer boundary and optional inner boundaries.

Map(mode: .hybrid) {
  Polygon(
    geometry: PolygonGeometry(path: [
      .init(latitude: 37.7749, longitude: -122.4194, altitude: 100),
      .init(latitude: 37.7750, longitude: -122.4193, altitude: 100),
      .init(latitude: 37.7751, longitude: -122.4192, altitude: 100),
    ])
  )
}

  • Returns a Boolean value indicating whether two values are equal.

    Equality is the inverse of inequality. For any values a and b, a == b implies that a != b is false.

    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 Hashable protocol. The components used for hashing must be the same as the components compared in your type’s == operator implementation. Call hasher.combine(_:) with each of these components.

    Important

    In your implementation of hash(into:), don’t call finalize() on the hasher instance 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

    hashValue is deprecated as a Hashable requirement. To conform to Hashable, implement the hash(into:) requirement instead. The compiler provides an implementation for hashValue for 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

    innerPaths

    Inner 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 path is empty, this polygon geometry will cover the whole earth with cut-outs for the inner paths.

    Declaration

    Swift

    init(path: [LatLngAltitude], innerPaths: [[LatLngAltitude]] = [])

    Parameters

    path

    Outer boundary of the polygon.
    innerPaths

    Inner 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]
