scanUnsafe	back to summary
public Object scanUnsafe(Scannable.Attr<T> key) Overrides reactor.core.publisher.InternalFluxOperator.scanUnsafe. Implements reactor.core.Scannable.scanUnsafe. Doc from reactor.core.Scannable.scanUnsafe. This method is used internally by components to define their key-value mappings in a single place. Although it is ignoring the generic type of the `Attr` key, implementors should take care to return values of the correct type, and return null if no specific value is available. For public consumption of attributes, prefer using `scan(Attr)`, which will return a typed value and fall back to the key's default if the component didn't define any mapping. Parameters key:Scannable.Attr<T> a `Attr` to resolve for the component. Returns:Object the value associated to the key for that specific component, or null if none. Annotations @Override

public CoreSubscriber<? super O> subscribeOrReturn(CoreSubscriber<? super O> actual) Implements abstract reactor.core.publisher.InternalFluxOperator.subscribeOrReturn. Implements reactor.core.publisher.OptimizableOperator.subscribeOrReturn. Doc from reactor.core.publisher.OptimizableOperator.subscribeOrReturn. Allow delegation of the subscription by returning a `CoreSubscriber`, or force subscription encapsulation by returning null. This can be used in conjunction with `nextOptimizableSource()` to perform subscription in a loop instead of by recursion. Returns:CoreSubscriber<? super O> next `CoreSubscriber` or "null" if the subscription was already done inside the method Annotations @Override

Invoked after calling `Publisher#subscribe(Subscriber)`. No data will start flowing until `Subscription#request(long)` is invoked. It is the responsibility of this `Subscriber` instance to call `Subscription#request(long)` whenever more data is wanted.

request	back to summary
public void request(long n) Implements org.reactivestreams.Subscription.request. Doc from org.reactivestreams.Subscription.request. No events will be sent by a `Publisher` until demand is signaled via this method. It can be called however often and whenever needed—but if the outstanding cumulative demand ever becomes Long.MAX_VALUE or more, it may be treated by the `Publisher` as "effectively unbounded". Whatever has been requested can be sent by the `Publisher` so only signal demand for what can be safely handled. A `Publisher` can send less than is requested if the stream ends but then must emit either `Subscriber#onError(Throwable)` or `Subscriber#onComplete()`. Parameters n:long the strictly positive number of elements to requests to the upstream `Publisher` Annotations @Override

requestFusion	back to summary
public int requestFusion(int requestedMode) Implements reactor.core.Fuseable.QueueSubscription.requestFusion. Doc from reactor.core.Fuseable.QueueSubscription.requestFusion. Request a specific fusion mode from this QueueSubscription. One should request either SYNC, ASYNC or ANY modes (never NONE) and the implementor should return NONE, SYNC or ASYNC (never ANY). For example, if a source supports only ASYNC fusion but the intermediate operator supports only SYNC fuseable sources, the operator may request SYNC fusion and the source can reject it via NONE, thus the operator can return NONE as well to downstream and the fusion doesn't happen. Parameters requestedMode:int the mode requested by the intermediate operator Returns:int the actual fusion mode activated Annotations @Override
