trait Observable[T] extends AnyRef

Observable, as the name suggests, observes values being fired against it. This is the core functionality of Reactify and provides the infrastructure used by Channel, Val, Var, Prop, and Dep.

T

the type of value this Observable will receive

  6. def attach(f: (T) ⇒ Unit, priority: Double = Observer.Priority.Normal): Observer[T]

    Attaches a function to observe values fired against this Observable.

    Attaches a function to observe values fired against this Observable.

    f

    function observer

    returns

    the supplied function. This reference is useful for detaching the function later

  7. def changes(observer: ChangeObserver[T]): Observer[T]

    Works similarly to attach, but also references the previous value that was fired.

    Works similarly to attach, but also references the previous value that was fired. This is useful when you need to handle changes, not just new values.

    observer

    the ChangeObserver

    returns

    the observer attached. This can be passed to detach to remove this observer

  8. def clearObservers(): Unit

    Clears all attached observers from this Observable.

    Detaches a function from observing this Observable.

    Detaches a function from observing this Observable.

    observer

    function observer that was previously attached

  18. def future(condition: (T) ⇒ Boolean = (_: T) => true): Future[T]

    Returns a Future[T] that represents the value of the next firing of this Observable.

    Returns a Future[T] that represents the value of the next firing of this Observable.

    condition

    the condition under which the observer will be invoked. Defaults to always return true.

  22. def map[R](f: (T) ⇒ R): Observable[R]

    Maps the Observable to another type.

    Maps the Observable to another type.

    R

    the type of the new Observable

    f

    function to handle the mapping from T to R

    returns

    Observable[R]

  26. def observe(observer: Observer[T]): Observer[T]

    Direct attachment of a observer.

    Direct attachment of a observer.

    observer

    the observer to attach

    returns

    the same observer supplied

  27. def observers: List[Observer[T]]

    List of all the observers currently observing changes to this Observable.

  28. def on(f: ⇒ Unit, priority: Double = Observer.Priority.Normal): Observer[T]

    Works like attach, but doesn't receive the fired value.

    Works like attach, but doesn't receive the fired value.

    f

    function to invoke on fire

    returns

    observer

  29. def once(f: (T) ⇒ Unit, condition: (T) ⇒ Boolean = (_: T) => true, priority: Double = Observer.Priority.Normal): Observer[T]

    Invokes the observer only one time and then detaches itself.

    Invokes the observer only one time and then detaches itself. If supplied, the condition filters the scenarios in which the observer will be invoked.

    f

    the function observer

    condition

    the condition under which the observer will be invoked. Defaults to always return true.
