Exposes the 'rails' as individual GroupedFlux instances, keyed by the rail index (zero based).

Each group can be consumed only once; requests and cancellation compose through. Note that cancelling only one rail may result in undefined behavior.

Method Detail

scanUnsafeback to summary
public Object scanUnsafe(Scannable.Attr<T> key)

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.

onNextback to summary
public void onNext(T t)

Doc from org.reactivestreams.Subscriber.onNext.

Data notification sent by the Publisher in response to requests to Subscription#request(long).

Parameters
t:T

the element signaled

Annotations
@Override
onSubscribeback to summary
public void onSubscribe(Subscription s)

Implements reactor.core.CoreSubscriber.onSubscribe.

Doc from reactor.core.CoreSubscriber.onSubscribe.

Implementors should initialize any state used by onNext(Object) before calling Subscription#request(long). Should further onNext related state modification occur, thread-safety will be required.

Note that an invalid request <= 0 will not produce an onError and will simply be ignored or reported through a debug-enabled reactor.util.Logger. 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.

The Publisher will send notifications only in response to Subscription#request(long).

Parameters
s:Subscription

Doc from org.reactivestreams.Subscriber.onSubscribe.

the Subscription that allows requesting data via Subscription#request(long)

Annotations
@Override
requestback 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
