public SingleSource<T> source()

Implements io.reactivex.internal.fuseable.HasUpstreamSingleSource.source.

Doc from io.reactivex.internal.fuseable.HasUpstreamSingleSource.source.

Returns the upstream source of this Single.

Allows discovering the chain of observables.

Returns:SingleSource<T>

the source SingleSource

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

Implements abstract io.reactivex.Maybe.subscribeActual.

Doc from io.reactivex.Maybe.subscribeActual.

Implement this method in subclasses to handle the incoming MaybeObservers.

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

Parameters
observer:MaybeObserver<? super T>

the MaybeObserver to handle, not null

public void
dispose()

Implements io.reactivex.disposables.Disposable.dispose.

Dispose the resource, the operation should be idempotent.
public boolean
isDisposed()

Implements io.reactivex.disposables.Disposable.isDisposed.

Returns true if this resource has been disposed.
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.
