Modifier and Type	Method and Description
public Object	scanUnsafe(Scannable.Attr<T> a `Attr` to resolve for the component. key) Overrides reactor.core.publisher.InternalMonoOperator.scanUnsafe. Implements reactor.core.Scannable.scanUnsafe. This method is used internally by components to define their key-value mappings in a single place.
public CoreSubscriber<? super T>	subscribeOrReturn(CoreSubscriber<? super T> actual) Implements abstract reactor.core.publisher.InternalMonoOperator.subscribeOrReturn. Implements reactor.core.publisher.OptimizableOperator.subscribeOrReturn. Allow delegation of the subscription by returning a `CoreSubscriber`, or force subscription encapsulation by returning null.

scanUnsafe	back to summary
public Object scanUnsafe(Scannable.Attr<T> key) Overrides reactor.core.publisher.InternalMonoOperator.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

subscribeOrReturn	back to summary
public CoreSubscriber<? super T> subscribeOrReturn(CoreSubscriber<? super T> actual) Implements abstract reactor.core.publisher.InternalMonoOperator.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 T> next `CoreSubscriber` or "null" if the subscription was already done inside the method Annotations @Override

Class Inheritance

extends MonoMetrics.MetricsSubscriber<T>
implements Fuseable, Fuseable.QueueSubscription<T>

java.lang.Object
reactor.core.publisher.MonoMetrics.MetricsSubscriber
reactor.core.publisher.MonoMetricsFuseable.MetricsFuseableSubscriber

All Implemented Interfaces

reactor.core.Fuseable.QueueSubscription, org.reactivestreams.Subscription, java.util.Queue, java.util.Collection, java.lang.Iterable, reactor.core.Fuseable

Implementation Note

we don't want to particularly track fusion-specific calls, as this subscriber would only detect fused subsequences immediately upstream of it, so Counters would be a bit irrelevant. We however want to instrument onNext counts.

requestFusion	back to summary
public int requestFusion(int mode) 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 mode:int the mode requested by the intermediate operator Returns:int the actual fusion mode activated Annotations @Override
