Method Summary

Modifier and TypeMethod and Description
pack-priv boolean
add(SingleCache.CacheDisposable<T> observer)

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.
pack-priv void
remove(SingleCache.CacheDisposable<T> observer)

protected void
subscribeActual(final SingleObserver<? super T>
the SingleObserver to handle, not null
observer)

Implements abstract io.reactivex.Single.subscribeActual.

Implement this method in subclasses to handle the incoming SingleObservers.

onErrorback to summary
public void onError(Throwable e)

Implements io.reactivex.SingleObserver.onError.

Doc from io.reactivex.SingleObserver.onError.

Notifies the SingleObserver that the Single has experienced an error condition.

If the Single calls this method, it will not thereafter call onSuccess.

Parameters
e:Throwable

the exception encountered by the Single

onSubscribeback to summary
public void onSubscribe(Disposable d)

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

the Disposable instance whose Disposable#dispose() can be called anytime to cancel the connection

Annotations

onSuccessback to summary
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

the item emitted by the Single

subscribeActualback to summary
protected void subscribeActual(final SingleObserver<? super T> observer)

Implements abstract io.reactivex.Single.subscribeActual.

Doc from io.reactivex.Single.subscribeActual.

Implement this method in subclasses to handle the incoming SingleObservers.

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

Parameters
observer:SingleObserver<? super T>

the SingleObserver to handle, not null
