IViewableList

interface IViewableList<out V : Any> : List<V> , IViewable<Pair<Int, V>> , ISource<IViewableList.Event<V>>

A list allowing its contents to be observed.

Types

sealed class Event<out V>

Represents an addition, update or removal of an element in the list.

Functions

abstract fun advise(lifetime: Lifetime, handler: (IViewableList.Event<V>) -> 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.

adviseAddRemove

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

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.

open override fun view(lifetime: Lifetime, handler: (Lifetime, Pair<Int, V>) -> Unit)

Adds a subscription to changes of the contents of the list.

open fun view(lifetime: Lifetime, handler: (Lifetime, Int, V) -> Unit)
