Returns:

the new SingleObserver instance
create(Observer<? super T>
the downstream Observer to talk to
downstream)

Creates a SingleObserver wrapper around a Observer.

public void
subscribeActual(final Observer<? super T>
the incoming Observer, never null
observer)

Implements abstract 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.

public static <T> SingleObserver<T> create(Observer<? super T> downstream)

Creates a SingleObserver wrapper around a Observer.

History: 2.0.1 - experimental

Parameters
<T>
the value type
downstream:Observer<? super T>

the downstream Observer to talk to

Returns:SingleObserver<T>

the new SingleObserver instance

subscribeActualback to summary
public void subscribeActual(final 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

Method Summary

Modifier and TypeMethod and Description
public void
dispose()

Overrides io.reactivex.internal.observers.DeferredScalarDisposable.dispose.

Implements io.reactivex.disposables.Disposable.dispose.

Dispose the resource, the operation should be idempotent.
public void
onError(Throwable
the exception encountered by the Single
e)

Implements io.reactivex.SingleObserver.onError.

Notifies the SingleObserver that the Single has experienced an error condition.
public void
onSubscribe(Disposable
the Disposable instance whose Disposable#dispose() can be called anytime to cancel the connection
d)

Implements io.reactivex.SingleObserver.onSubscribe.

Provides the SingleObserver with the means of cancelling (disposing) the connection (channel) with the Single in both synchronous (from within onSubscribe(Disposable) itself) and asynchronous manner.
public void
onSuccess(T
the item emitted by the Single
value)

Implements io.reactivex.SingleObserver.onSuccess.

Notifies the SingleObserver with a single item and that the Single has finished sending push-based notifications.

public void onError(Throwable e)

Implements io.reactivex.SingleObserver.onError.

Implements io.reactivex.SingleObserver.onSubscribe.

Doc from io.reactivex.SingleObserver.onSubscribe.

Provides the SingleObserver with the means of cancelling (disposing) the connection (channel) with the Single in both synchronous (from within onSubscribe(Disposable) itself) and asynchronous manner.

Parameters
d:Disposable

public void onSuccess(T value)

Implements io.reactivex.SingleObserver.onSuccess.

Doc from io.reactivex.SingleObserver.onSuccess.

Notifies the SingleObserver with a single item and that the Single has finished sending push-based notifications.

The Single will not call this method if it calls onError.

Parameters
value:T
