public final Class ObservableThrottleLatest<T>

extends AbstractObservableWithUpstream<T, T>
Class Inheritance
Type Parameters
<T>
the upstream and downstream value type
Imports
java.util.concurrent.TimeUnit, java.util.concurrent.atomic.*, io.reactivex.*, io.reactivex.disposables.Disposable, io.reactivex.internal.disposables.DisposableHelper

Emits the next or latest item when the given time elapses.

The operator emits the next item, then starts a timer. When the timer fires, it tries to emit the latest item from upstream. If there was no upstream item, in the meantime, the next upstream item is emitted immediately and the timed process repeats.

History: 2.1.14 - experimental

Since
2.2

protected void subscribeActual(Observer<? super T> observer)

Implements abstract io.reactivex.Observable.subscribeActual.

Doc from io.reactivex.Observable.subscribeActual.

Operator implementations (both source and intermediate) should implement this method that performs the necessary business logic and handles the incoming Observers.

There is no need to call any of the plugin hooks on the current Observable instance or the Observer; all hooks and basic safeguards have been applied by subscribe(Observer) before this method gets called.

Parameters
observer:Observer<? super T>

the incoming Observer, never null

onCompleteback to summary
public void onComplete()

Implements io.reactivex.Observer.onComplete.
