onNext
public void onNext(T t)
-
tryOnNext
public boolean tryOnNext(T t)
Description copied from interface:ConditionalSubscriber
Conditionally takes the value.- Parameters:
t
- the value to deliver- Returns:
- true if the value has been accepted, false if the value has been rejected and the next value can be sent immediately
-
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.- 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
.

poll
@Nullable public T poll() throws java.lang.Throwable
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.- Returns:
- the item or null to indicate an empty queue
- Throws:
java.lang.Throwable
- if some pre-processing of the dequeued item (usually through fused functions) throws.
