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)

adviseAddRemove

open fun adviseAddRemove(lifetime: Lifetime, handler: (AddRemove, K, V) -> Unit)

Adds a subscription to additions and removals of map elements. When a map element is updated, the handler is called twice: to report the removal of the old element and the addition of the new one.

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

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.
