AddressComponent
struct AddressComponent
extension AddressComponent : CustomStringConvertible, Equatable, Hashable
Represents a component of an address, e.g., street number, postcode, city, etc.
-
Returns a Boolean value indicating whether two values are equal.
Equality is the inverse of inequality. For any values
a
andb
,a == b
implies thata != b
isfalse
.Declaration
Swift
static func == (lhs: AddressComponent, rhs: AddressComponent) -> Bool
Parameters
lhs
A value to compare.
rhs
Another value to compare.
-
A textual representation of this instance.
Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the
String(describing:)
initializer. This initializer works with any type, and uses the customdescription
property for types that conform toCustomStringConvertible
:struct Point: CustomStringConvertible { let x: Int, y: Int var description: String { return "(\(x), \(y))" } } let p = Point(x: 21, y: 30) let s = String(describing: p) print(s) // Prints "(21, 30)"
The conversion of
p
to a string in the assignment tos
uses thePoint
type’sdescription
property.Declaration
Swift
var description: String { get }
-
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. Callhasher.combine(_:)
with each of these components.Important
In your implementation of
hash(into:)
, don’t callfinalize()
on thehasher
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 aHashable
requirement. To conform toHashable
, implement thehash(into:)
requirement instead. The compiler provides an implementation forhashValue
for you.Declaration
Swift
var hashValue: Int { get }
-
Instantiates an
AddressComponent
with the specified information.AddressComponent
s can be gotten from aPlace
object. This initializer can be used for testing.Declaration
Swift
init(types: Set<PlaceType>, name: String, shortName: String? = nil)
Return Value
An
AddressComponent
containing the specified information. -
Name of the address component, e.g. “Sydney”
Declaration
Swift
var name: String { get }
-
Short name of the address component, e.g. “AU”
Declaration
Swift
var shortName: String? { get }
-
Types associated with the address component. For a list of supported types, see https://developers.google.com/places/ios-sdk/supported_types#table2. This set will contain one or more
PlaceType
defined in PlaceTypes.swift.Declaration
Swift
var types: Set<PlaceType> { get }
