Method Details

onSubscribe

public void onSubscribe(Disposable d)

Description copied from interface: Observer

Provides the Observer with the means of cancelling (disposing) the connection (channel) with the Observable in both synchronous (from within Observer.onNext(Object)) and asynchronous manner.

Specified by:

onSubscribe in interface Observer<T>

Parameters:

d - the Disposable instance whose Disposable.dispose() can be called anytime to cancel the connection

onNext

public void onNext(T value)

Description copied from interface: Observer

Provides the Observer with a new item to observe.

The Observable may call this method 0 or more times.

The Observable will not call this method again after it calls either Observer.onComplete() or Observer.onError(java.lang.Throwable).

Specified by:

onNext in interface Observer<T>

Parameters:

value - the item emitted by the Observable

onError

public void onError(Throwable e)

Description copied from interface: Observer

Notifies the Observer that the Observable has experienced an error condition.

If the Observable calls this method, it will not thereafter call Observer.onNext(T) or Observer.onComplete().

Specified by:

onError in interface Observer<T>

Parameters:

e - the exception encountered by the Observable

onComplete

public void onComplete()

Description copied from interface: Observer

Notifies the Observer that the Observable has finished sending push-based notifications.

The Observable will not call this method if it calls Observer.onError(java.lang.Throwable).

Specified by:

onComplete in interface Observer<T>

dispose

public void dispose()

Description copied from interface: Disposable

Dispose the resource, the operation should be idempotent.

Specified by:

dispose in interface Disposable

isDisposed

public boolean isDisposed()

Description copied from interface: Disposable

Returns true if this resource has been disposed.

Specified by:

isDisposed in interface Disposable

Returns:

true if this resource has been disposed

poll

@Nullable
public T poll()

Description copied from interface: SimpleQueue

Tries to dequeue a value (non-null) or returns null if the queue is empty.

If the producer uses SimpleQueue.offer(Object, Object) and when polling in pairs, if the first poll() returns a non-null item, the second poll() is guaranteed to return a non-null item as well.

Specified by:

poll in interface SimpleQueue<T>

Returns:

the item or null to indicate an empty queue

isEmpty

public boolean isEmpty()

Description copied from interface: SimpleQueue

Returns true if the queue is empty.

Note however that due to potential fused functions in SimpleQueue.poll() it is possible this method returns false but then poll() returns null because the fused function swallowed the available item(s).

Specified by:

isEmpty in interface SimpleQueue<T>

Returns:

true if the queue is empty

clear

public void clear()

Description copied from interface: SimpleQueue

Removes all enqueued items from this queue.

Specified by:

clear in interface SimpleQueue<T>

requestFusion

public int requestFusion(int mode)

Description copied from interface: QueueFuseable

Request a fusion mode from the upstream.

This should be called before onSubscribe returns.

Calling this method multiple times or after onSubscribe finished is not allowed and may result in undefined behavior.

Specified by:

requestFusion in interface QueueFuseable<T>

Parameters:

mode - the requested fusion mode, allowed values are QueueFuseable.SYNC, QueueFuseable.ASYNC, QueueFuseable.ANY combined with QueueFuseable.BOUNDARY (e.g., requestFusion(SYNC | BOUNDARY)).

Returns:

the established fusion mode: QueueFuseable.NONE, QueueFuseable.SYNC, QueueFuseable.ASYNC.

innerComplete

void innerComplete(ObservableFlatMapCompletable.FlatMapCompletableMainObserver<T>.InnerObserver inner)

innerError

void innerError(ObservableFlatMapCompletable.FlatMapCompletableMainObserver<T>.InnerObserver inner,
 Throwable e)
