This qualifier can be used to inject a stream containing the items and signals propagated by the specified channel. For example, it can be used to @Inject a Publisher representing a channel managed by the Reactive Messaging implementation.

Can be injected:

• Publisher<X> with X the payload type
• Publisher<Message<X>> with X the payload type
• Flowable<X> with X the payload type
• Flowable<Message<X>> with X the payload type
• PublisherBuilder<Message<X>> with X the payload type
• PublisherBuilder<X> with X the payload type

When this qualifier is used on an Emitter, it indicates which channel received the emitted values / signals:

 
 @Inject @Stream("my-channel") Emitter<String> emitter;

 // ...
 emitter.send("a").send("b").complete();
