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

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 T> next `CoreSubscriber` or "null" if the subscription was already done inside the method Annotations @Override @SuppressWarnings:unchecked

onSubscribe	back 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

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

poll back to summary

public R poll()

Implements java.util.Queue.poll.

Returns:R

Annotations

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

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

Overrides default reactor.core.publisher.InnerProducer.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

size back to summary

public int size()

Implements java.util.Collection.size.

Doc from java.util.Collection.size.

Returns the number of elements in this collection. If this collection contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

Returns:int
