RVS_GeneralObserverSubTrackerProtocol

public protocol RVS_GeneralObserverSubTrackerProtocol : AnyObject, RVS_GeneralObserverProtocol

This is a class protocol, so we can mutate the properties in the protocol extension, and we won’t have the issue of unlinked references.

  • This is where we will track our subscriptions.

    Declaration

    Swift

    var subscriptions: [RVS_GeneralObservableProtocol] { get set }
  • unsubscribeAll() Default implementation

    This unsubs the observer from all of its subscriptions.

    Default Implementation

    Default unsubs us from all of our subscriptions.

    Declaration

    Swift

    @discardableResult
func unsubscribeAll() -> [RVS_GeneralObservableProtocol]

    Return Value

    An Array, of all the observables it unsubbed from.

INTERNAL-USE ONLY

  • internalSubscribedTo(_:) Default implementation

    This is called after being subscribed to an Observable.

    This is a method that is unique to this protocol, and is used for internal management.

    This is called after the Observable’s observer(_:, didSubscribe:) method was called.

    In the default implementation, this is called in the subscription execution context, so that will be the thread used for the callback.

    Default Implementation

    Default simply adds the observable to our list.

    Declaration

    Swift

    func internalSubscribedTo(_ inObservableInstance: RVS_GeneralObservableProtocol)
  • internalUnsubscribedFrom(_:) Default implementation

    This is called after being unsubscribed from an Observable.

    This is a method that is unique to this protocol, and is used for internal management.

    This is called after the Observable’s observer(_:, didSubscribe:) method was called.

    In the default implementation, this is called in the unsubscription execution context, so that will be the thread used for the callback.

    Default Implementation

    Default simply removes the observable from our list.

    Declaration

    Swift

    func internalUnsubscribedFrom(_ inObservableInstance: RVS_GeneralObservableProtocol)
