pack-priv abstract Class InternalFluxOperator<I, O>

Implements reactor.core.publisher.OptimizableOperator.nextOptimizableSource.

Doc from reactor.core.publisher.OptimizableOperator.nextOptimizableSource.

Allow delegation of the subscription by returning the next OptimizableOperator UP in the chain, to be subscribed to next. This method MUST return a non-null value if the subscribeOrReturn(CoreSubscriber) method returned a non null value. In that case, this next operator can be used in conjunction with subscribeOrReturn(CoreSubscriber) to perform subscription in a loop instead of by recursion.

Returns:OptimizableOperator<?, ? extends I>

next OptimizableOperator if subscribeOrReturn(CoreSubscriber) have returned non-null result

Overrides reactor.core.publisher.FluxOperator.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.

Returns:CorePublisher<? extends I>

Doc from reactor.core.publisher.OptimizableOperator.source.

CorePublisher to call CorePublisher#subscribe(CoreSubscriber) on if nextOptimizableSource() have returned null result

@Override

Implements abstract reactor.core.publisher.Flux.subscribe.

Implements reactor.core.CorePublisher.subscribe.

Doc from reactor.core.CorePublisher.subscribe.

An internal Publisher#subscribe(Subscriber) that will bypass Hooks#onLastOperator(Function) pointcut.

In addition to behave as expected by Publisher#subscribe(Subscriber) in a controlled manner, it supports direct subscribe-time Context passing.

Parameters

subscriber:CoreSubscriber<? super O>

the Subscriber interested into the published sequence

Redeclares 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 I>

next CoreSubscriber or "null" if the subscription was already done inside the method
