Functions

advise

open override fun advise(lifetime: Lifetime, handler: (T) -> Unit)

Adds an event subscription. Every time an event occurs, the handler is called, receiving an instance of the event. The subscription is removed when the given lifetime expires.

advise

fun IVoidSource.advise(lifetime: Lifetime, handler: () -> Unit)

adviseEternal

fun <T> ISource<T>.adviseEternal(handler: (T) -> Unit)

Adds an event subscription that never gets removed.

adviseNotNull

fun <T : Any> ISource<T?>.adviseNotNull(lifetime: Lifetime, handler: (T) -> Unit)

Adds an event subscription that filters out null values.

adviseNotNullOnce

fun <T : Any> ISource<T?>.adviseNotNullOnce(lifetime: Lifetime, handler: (T) -> Unit): LifetimeDefinition

Executes handler exactly once when the source fires an event with a non-null value, then terminates the subscription

adviseOnce

fun <T> ISource<T>.adviseOnce(lifetime: Lifetime, handler: (T) -> Unit)

Executes handler exactly once then terminates the subscription

adviseSuspend

fun <T> ISource<T>.adviseSuspend(lifetime: Lifetime, scheduler: IScheduler, handler: suspend (T) -> Unit)

fun <T> ISource<T>.adviseSuspend(lifetime: Lifetime, context: CoroutineContext, handler: suspend (T) -> Unit)

adviseUntil

fun <T> ISource<T>.adviseUntil(lifetime: Lifetime, handler: (T) -> Boolean)

Holds subscription until handler returns true or lifetime is terminated

adviseWithPrev

fun <T> ISource<T>.adviseWithPrev(lifetime: Lifetime, handler: (prev: Maybe<T>, cur: T) -> Unit)

asFlow

fun <T> ISignal<T>.asFlow(): SignalFlow<T>

asProperty

fun <T> ISource<T>.asProperty(defaultValue: T): IPropertyView<T>

distinct

fun <T> ISource<T>.distinct(): ISource<T>

filter

fun <T> ISource<T>.filter(f: (T) -> Boolean): ISource<T>

fire

open override fun fire(value: T)

fire

fun IVoidSignal.fire()

flowInto

fun <TSrc> ISource<TSrc>.flowInto(lifetime: Lifetime, target: IMutablePropertyBase<TSrc>)

fun <TSrc : Any, TDst : Any> ISource<IViewableList.Event<TSrc>>.flowInto(lifetime: Lifetime, target: IMutableViewableList<TDst>, tf: (TSrc) -> TDst)

fun <TKey : Any, TValue : Any> ISource<IViewableMap.Event<TKey, TValue>>.flowInto(lifetime: Lifetime, target: IMutableViewableMap<TKey, TValue>, tf: (TValue) -> TValue)

fun <TSrc : Any, TDst : Any> ISource<IViewableSet.Event<TSrc>>.flowInto(lifetime: Lifetime, target: IMutableViewableSet<TDst>, tf: (TSrc) -> TDst)

fun <T> ISource<T>.flowInto(lifetime: Lifetime, target: ISignal<T>)

Whenever a change happens in this source, fires a change in the target signal of the same type.

fun <TSrc, TDst> ISource<TSrc>.flowInto(lifetime: Lifetime, target: IMutablePropertyBase<TDst>, tf: (TSrc) -> TDst)

Whenever a change happens in this source, changes the target property of the same type.

fun <TSource, TTarget> ISource<TSource>.flowInto(lifetime: Lifetime, target: ISignal<TTarget>, tf: (TSource) -> TTarget)

Whenever a change happens in this source, fires a change in the target signal obtained by running the given tf function.

map

fun <T, R> ISource<T>.map(f: (T) -> R): ISource<R>

Returns a new source which remaps events happening in this source using the given function f.
