AbstractBaseDefaultSubject

Properties

abstract val current: R

The current value of R

abstract val currentOrNull: T?

The current value T or null being observed

abstract val defaultValue: ObservableOptional.Value<R>

Functions

abstract fun observe(onNext: (R?) -> Unit): Disposable

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

observeInitialized

abstract fun observeInitialized(onNext: (R) -> Unit): Disposable

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.
