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

Adds a subscription to additions and removals of list elements. When a list 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
