IPropertyView

interface IPropertyView<out T> : IPropertyBase<T>

A read-only property that can be observed.

Functions

open override fun advise(lifetime: Lifetime, handler: (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.

invoke

open operator fun invoke(): T

view

open override fun view(lifetime: Lifetime, handler: (Lifetime, T) -> Unit)

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

Properties

change

abstract val change: ISource<T>

Allows to subscribe to subsequent changes of the property value. Unlike subscribing to the property directly, the callback will not be immediately called with the current value of the property.

value

abstract val value: T

Returns the current value of the property.
