Interface Emitter<T>

Type Parameters:

T - the value type emitted

All Known Subinterfaces:

FlowableEmitter<T>, ObservableEmitter<T>

public interface Emitter<T>

Base interface for emitting signals in a push-fashion in various generator-like source operators (create, generate).

Note that the onNext(T), onError(java.lang.Throwable) and onComplete() methods provided to the function via the Emitter instance should be called synchronously, never concurrently. Calling them from multiple threads is not supported and leads to an undefined behavior.

Method Summary

Modifier and Type	Method and Description
void	onComplete() Signal a completion.
void	onError(@NonNull Throwable error) Signal a Throwable exception.
void	onNext(T value) Signal a normal value.
