Interface Summary
Interface	Description
Graph	A graph.
ReactiveStreamsEngine	An engine for turning reactive streams graphs into Reactive Streams publishers/subscribers.
Stage	A stage of a Reactive Streams graph.
Stage.Cancel	A cancelling stage.
Stage.Collect	A collect stage.
Stage.Concat	Concatenate the given graphs together.
Stage.Coupled	A stage that couples a wrapped subscriber graph to a wrapped publisher graph.
Stage.Distinct	A stage returning a stream consisting of the distinct elements (according to `Object.equals(Object)`) of this stream.
Stage.DropWhile	A drop while stage.
Stage.Failed	A failed publisher.
Stage.Filter	A filter stage.
Stage.FindFirst	A subscriber stage that emits the first element encountered.
Stage.FlatMap	A flat map stage.
Stage.FlatMapCompletionStage	A flat map stage that emits and flattens `CompletionStage`.
Stage.FlatMapIterable	A flat map stage that emits and fattens `Iterable`.
Stage.FromCompletionStage	A publisher representation of a `CompletionStage`.
Stage.FromCompletionStageNullable	A publisher representation of a `CompletionStage`.
Stage.Limit	A limit stage.
Stage.Map	A map stage.
Stage.Of	A publisher of zero to many values.
Stage.OnComplete	A stage returning a stream containing all the elements from this stream, additionally performing the provided action when this stream completes.
Stage.OnError	A stage returning a stream containing all the elements from this stream, additionally performing the provided action if this stream conveys an error.
Stage.OnErrorResume	A stage to handle errors from upstream.
Stage.OnErrorResumeWith	A stage to handle errors from upstream.
Stage.OnTerminate	A stage returning a stream containing all the elements from this stream, additionally performing the provided action if this stream terminates with an error, completes, or is cancelled by downstream.
Stage.Peek	A stage returning a stream containing all the elements from this stream, additionally performing the provided action on each element.
Stage.ProcessorStage	A processor stage.
Stage.PublisherStage	A publisher stage.
Stage.Skip	A skip stage.
Stage.SubscriberStage	A subscriber.
Stage.TakeWhile	A take while stage.
SubscriberWithCompletionStage<T,R>	A subscriber and completion stage pair.
ToGraphable	All instances of `PublisherBuilder`, `ProcessorBuilder`, `SubscriberBuilder` and `CompletionRunner` must implement this, to ensure that the builder can be turned into a graph by other implementations of the API.

Package org.eclipse.microprofile.reactive.streams.operators.spi Description

The Reactive Streams utils SPI. Implementors are expected to implement the ReactiveStreamsEngine interface, and use this SPI to inspect the graph of stages. A TCK is also provided that validates that an implementation is both correct according to this specification, and the Reactive Streams specification.
