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.

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

Adds a subscription for additions and removals of set elements. When the subscription is initially added, handler is called with AddRemove.Add events for all elements currently in the set.

advise

adviseEternal

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

Adds an event subscription that never gets removed.

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
