Class PerhapsProcessor<T>

java.lang.Object

hu.akarnokd.rxjava2.basetypes.Perhaps<T>

hu.akarnokd.rxjava2.basetypes.PerhapsProcessor<T>

Type Parameters:

T - the input and output value type

All Implemented Interfaces:

org.reactivestreams.Processor<T,T>, org.reactivestreams.Publisher<T>, org.reactivestreams.Subscriber<T>

public final class PerhapsProcessor<T>
extends Perhaps<T>
implements org.reactivestreams.Processor<T,T>

A Processor based on the Perhaps type that emits an onNext+onComplete, only onComplete or an onError.

Calling the onNext multiple times has no effect.

Since:

0.14.0
