Class SynchronizedObserver<T>

java.lang.Object
  rx.operators.SynchronizedObserver<T>

Type Parameters:

T -

All Implemented Interfaces:

Observer<T>

public final class SynchronizedObserver<T>
extends java.lang.Object
implements Observer<T>

A thread-safe Observer for transitioning states in operators.

Execution rules are:

• Allow only single-threaded, synchronous, ordered execution of onNext, onCompleted, onError
• Once an onComplete or onError are performed, no further calls can be executed
• If unsubscribe is called, this means we call completed() and don't allow any further onNext calls.

Constructor Summary

SynchronizedObserver(Observer<? super T> Observer)
Used when synchronizing an Observer without access to the subscription.

SynchronizedObserver(Observer<? super T> Observer, SafeObservableSubscription subscription)

Method Summary

void	onCompleted() Notifies the Observer that the Observable has finished sending push-based notifications.
void	onError(java.lang.Throwable e) Notifies the Observer that the Observable has experienced an error condition.
void	onNext(T arg) Provides the Observer with new data.
