abstract class BaseUninitializedObservable<T>(observation: ObservationUninitialized<T>) : BaseObservable<T, T, ObservableOptional<T>> , UninitializedObservable<T> , Uninitialized<T>

An abstract class extending BaseObservable that implements UninitializedObservable

Parameters

T

the type of value to expect.

observation

The ObservationUninitialized to handle observing the value.

Inheritors

Constructors

BaseUninitializedObservable

constructor(observation: ObservationUninitialized<T>)

Properties

open override val currentOrNull: T?

The current value T or null being observed

open override val initialValue: ObservableOptional.Nothing<T>

The initial ObservableOptional value of T.

expect open override val stateFlow: StateFlow<T?>

StateFlow that expresses the content from the observable.

expect open override val valueDelegate: ReadOnlyProperty<Any?, T?>

A ReadOnlyProperty of T

Functions

open operator override fun getValue(thisRef: Any?, property: KProperty<*>): ObservableOptional<T>

open override fun observe(onNext: (T?) -> Unit): Disposable

Creates an observation that calls onNext each time a new value is observed until the resulting Disposable is disposed

observeNotNullOnLifecycle

fun <T> WithState<T?>.observeNotNullOnLifecycle(lifecycleOwner: LifecycleOwner, filter: suspend (T) -> Boolean = { true }, onNext: (T) -> Unit): Job

Observes WithState of a nullable value on the lifecycle of a LifecycleOwner

observeOnLifecycle

fun <T> WithState<T>.observeOnLifecycle(lifecycleOwner: LifecycleOwner, filter: suspend (T) -> Boolean = { true }, onNext: (T) -> Unit): Job

Observes WithState on the lifecycle of a LifecycleOwner

fun <T, R> WithState<T>.observeOnLifecycle(lifecycleOwner: LifecycleOwner, filter: suspend (T) -> Boolean = { true }, transform: suspend (T) -> R, onNext: (R) -> Unit): Job

Observes WithState on the lifecycle of a LifecycleOwner by transforming the observed value.

toDefaultObservable

fun <R : T, T> ReadOnlyProperty<Any?, T?>.toDefaultObservable(defaultValue: R): ReadOnlyPropertyDefaultObservable<R, T?>

Converts a ReadOnlyProperty into a ReadOnlyPropertyDefaultObservable

toInitializedObservable

fun <T> ReadOnlyProperty<Any?, T>.toInitializedObservable(): ReadOnlyPropertyInitializedObservable<T>

Converts a ReadOnlyProperty into a ReadOnlyPropertyInitializedObservable
