AsyncReadablePropertyType

public protocol AsyncReadablePropertyType : AnyObject, AsyncPropertyType

Undocumented

  • The property’s value type.

    Declaration

    Swift

    associatedtype Value

  • The type of change delivered by the signal. For simple properties, this will be the same as Value, but for complex properties (e.g. where Value is an array or tree structure) this may be an enumerated type that indicates fine-grained changes to the value.

    Declaration

    Swift

    associatedtype SignalChange

  • Converts this instance into a concrete AsyncReadableProperty.

    Declaration

    Swift

    var property: AsyncReadableProperty<Value> { get }

  • The underlying signal.

    Declaration

    Swift

    var signal: Signal<SignalChange> { get }

  • The most recent value delivered by the underlying signal.

    Declaration

    Swift

    var value: Value? { get }
  • start() Extension method

    Declaration

    Swift

    public func start()

Operations
  • map(_:) Extension method

    Returns an AsyncReadableProperty whose value is derived from this property’s value. The given transform will be applied whenever this property’s value changes.

    Declaration

    Swift

    public func map<U>(_ transform: @escaping (Self.Value) -> U) -> AsyncReadableProperty<U>
  • flatMap(_:) Extension method

    Returns an AsyncReadableProperty whose value is derived from the given property’s value. The given transform will be applied whenever this property’s value changes, and in turn the property returned by transform becomes the new source of values.

    Declaration

    Swift

    public func flatMap<P: AsyncReadablePropertyType>(_ transform: @escaping (Self.Value) -> P) -> AsyncReadableProperty<P.Value>
    where P.Value == P.SignalChange
