      • apply

        org.reactivestreams.Publisher<CacheEntry<K,​V>> apply​(SegmentPublisherSupplier.Notification<CacheEntry<K,​V>> cacheEntryNotification)
                                                            throws Throwable
        This should be invoked on a notification before actually processing the data. Note this method modifies the underlying listener state. It will return a Publisher with the entries that need to be notified or an empty Publisher if none
        Specified by:
        apply in interface io.reactivex.rxjava3.functions.Function<K,​V>
        cacheEntryNotification - The notification being processed
        a Publisher that returns all the CacheEntries that need to be notified
      • handleEvent

        boolean handleEvent​(EventWrapper<K,​V,​E> wrapper,
                            ListenerInvocation<Event<K,​V>> invocation)
        This should be called by any listener when an event is generated to possibly queue it. If it is not queued, then the caller should take appropriate action such as manually firing the invocation.
        wrapper - The event that was just raised
        invocation - The invocation the event would be fired on
        Whether or not it was queued. If it wasn't queued the invocation should be fired manually
      • transferComplete

        CompletionStage<Void> transferComplete()
        This is needed to tell the handler when the complete iteration is done. Depending on the implementation this could also fire all queued events that are remaining.
