Class MaybeToObservable<T>

java.lang.Object
io.reactivex.rxjava3.core.Observable<T>
io.reactivex.rxjava3.internal.operators.maybe.MaybeToObservable<T>
Type Parameters:
T - the value type
All Implemented Interfaces:
ObservableSource<T>, HasUpstreamMaybeSource<T>

public final class MaybeToObservable<T> extends Observable<T> implements HasUpstreamMaybeSource<T>
Wraps a MaybeSource and exposes it as an Observable, relaying signals in a backpressure-aware manner and composes cancellation through.

  • Method Details

    • source

      public MaybeSource<T> source()
      Description copied from interface: HasUpstreamMaybeSource
      Returns the upstream source of this Maybe.

      Allows discovering the chain of observables.

      Specified by:
      source in interface HasUpstreamMaybeSource<T>
      Returns:
      the source MaybeSource
    • subscribeActual

      protected void subscribeActual(Observer<? super T> observer)
      Description copied from class: Observable
      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 Observable.subscribe(Observer) before this method gets called.

      Specified by:
      subscribeActual in class Observable<T>
      Parameters:
      observer - the incoming Observer, never null
    • create

      public static <T> MaybeObserver<T> create(Observer<? super T> downstream)
      Creates a MaybeObserver wrapper around a Observer.

      History: 2.1.11 - experimental

      Type Parameters:
      T - the value type
      Parameters:
      downstream - the downstream Observer to talk to
      Returns:
      the new MaybeObserver instance
