Observable

public protocol Observable

Observable is an interface for a container of observers. It allows sending notifications on certain events to all of the added observers.

We provide the implementation of this protocol: TomTomSDKCommon/ObservableHandler.


                    
                    
                    addObserver(_:)

Add an Observer in the Observable container.

Swift

func addObserver(_ observer: Observer)


                                observer

Observer to add.


                    
                    
                    notifyObservers(notificationAction:)

Notify observers about some specific event.

Swift

func notifyObservers(notificationAction: @escaping (Observer) -> ())


                                notificationAction

Use the closure to define what event every observer will receive. This method applies the notificationAction closure to every added observer.


                    
                    
                    notifyObservers(notificationAction:completion:)

Notify observers about some specific event.

Swift

func notifyObservers(notificationAction: @escaping (Observer) -> (), completion: (() -> ())?)

`notificationAction`	Use the closure to define what event every observer will receive. This method applies the `notificationAction` closure to every added observer.
`completion`	Called when the `notificationAction` closure is applied to all the added observers.


                    
                    
                    removeObserver(_:)

Remove an Observer.

Swift

func removeObserver(_ observer: Observer)


                                observer

Observer to remove.
