onSubscribe
public void onSubscribe(org.reactivestreams.Subscription s)
Description copied from interface:FlowableSubscriber
Implementors of this method should make sure everything that needs to be visible inSubscriber.onNext(Object)
is established before callingSubscription.request(long)
. In practice this means no initialization should happen after therequest()
call and additional behavior is thread safe in respect toonNext

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(FlowableFlatMapCompletable.FlatMapCompletableMainSubscriber.InnerConsumer inner)
