IViewableSet

interface IViewableSet<T : Any> : Set<T> , IViewable<T> , ISource<IViewableSet.Event<T>>

A set allowing its contents to be observed.

Types

data class Event<T>(val kind: AddRemove, val value: T)

Represents an addition or removal of an element in the set.

Functions

abstract fun advise(lifetime: Lifetime, handler: (IViewableSet.Event<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.

open fun advise(lifetime: Lifetime, handler: (AddRemove, T) -> 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.
