Method Detail

onSubscribe
public void onSubscribe(Disposable d)
Description copied from interface:Observer
Provides theObserver
with the means of cancelling (disposing) the connection (channel) with theObservable
in both synchronous (from withinObserver.onNext(Object)
) and asynchronous manner.- Specified by:
onSubscribe
in interfaceObserver<T>
- Parameters:
d
- theDisposable
instance whoseDisposable.dispose()
can be called anytime to cancel the connection
-
onNext
public void onNext(T value)
Description copied from interface:Observer
Provides theObserver
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 eitherObserver.onComplete()
orObserver.onError(java.lang.Throwable)
.
-
onError
public void onError(java.lang.Throwable e)
Description copied from interface:Observer
Notifies theObserver
that theObservable
has experienced an error condition.If the
Observable
calls this method, it will not thereafter callObserver.onNext(T)
orObserver.onComplete()
.
-
onComplete
public void onComplete()
Description copied from interface:Observer
Notifies theObserver
that theObservable
has finished sending push-based notifications.The
Observable
will not call this method if it callsObserver.onError(java.lang.Throwable)
.- Specified by:
onComplete
in interfaceObserver<T>
-
dispose
public void dispose()
Description copied from interface:Disposable
Dispose the resource, the operation should be idempotent.- Specified by:
dispose
in interfaceDisposable
-
isDisposed
public boolean isDisposed()
Description copied from interface:Disposable
Returns true if this resource has been disposed.- Specified by:
isDisposed
in interfaceDisposable
- 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 interfaceSimpleQueue<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 interfaceSimpleQueue<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 interfaceSimpleQueue<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 interfaceQueueFuseable<T>
- Parameters:
mode
- the requested fusion mode, allowed values areQueueFuseable.SYNC
,QueueFuseable.ASYNC
,QueueFuseable.ANY
combined withQueueFuseable.BOUNDARY
(e.g.,requestFusion(SYNC | BOUNDARY)
).- Returns:
- the established fusion mode:
QueueFuseable.NONE
,QueueFuseable.SYNC
,QueueFuseable.ASYNC
.
-
innerComplete
void innerComplete(ObservableFlatMapCompletable.FlatMapCompletableMainObserver.InnerObserver inner)
-
innerError
void innerError(ObservableFlatMapCompletable.FlatMapCompletableMainObserver.InnerObserver inner, java.lang.Throwable e)
