CollisionBehavior
enum CollisionBehavior
extension CollisionBehavior : Equatable, Hashable
-
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: CollisionBehavior, b: CollisionBehavior) -> 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 }
-
Specifies that the marker should only be displayed if it does not overlap
with other markers. If two markers of this type would overlap, the one with
the higher draw order is shown. If they have the same draw order, the one
with the lower vertical screen position is shown.
Declaration
Swift
case optionalAndHidesLowerPriority
-
Specifies that the marker should always be displayed regardless of
collision.
-
Specifies that the marker should always be displayed regardless of
collision. Markers with OPTIONAL_AND_HIDES_LOWER_PRIORITY collision
behavior or the default map labels that overlap with this marker will be
hidden.
Declaration
Swift
case requiredAndHidesOptional
