Types

This interface is an asynchronous variation to the ObservableProperty. Used if the initial value is undefined. It doesn't provide a value if it hasn't been assigned yet, but you can block the thread until it is.

MutableObservableProperty

interface MutableObservableProperty<T> : ObservableProperty<T>

ObservableProperty with the added functionality of a mutable value.

ObservableProperty

interface ObservableProperty<T>

A synchronous property delegate accessor.

ValueChangeListener

interface ValueChangeListener<OLD, NEW>

Implemented by listeners to observe ObservableProperty and DeferredObservableProperty value changes.

ViewModelProperty

typealias ViewModelProperty<T> = ObservableProperty<T>

Functions

asChannel

fun <T> ObservableProperty<T>.asChannel(): Channel<T>

Conversion method to Channel.

asFlow

fun <T> ObservableProperty<T>.asFlow(): Flow<T>

Conversion method to Flow.

combine

fun <T> combine(sources: List<ObservableProperty<T>>): ObservableProperty<List<T>>
