Method Summary

Modifier and Type	Method	Description
(package private) boolean	add(ObservableReplay.InnerDisposable<T> producer)	Atomically try adding a new InnerDisposable to this Observer or return false if this Observer was terminated.
void	dispose()	Dispose the resource, the operation should be idempotent.
boolean	isDisposed()	Returns true if this resource has been disposed.
void	onComplete()	Notifies the Observer that the Observable has finished sending push-based notifications.
void	onError(Throwable e)	Notifies the Observer that the Observable has experienced an error condition.
void	onNext(T t)	Provides the Observer with a new item to observe.
void	onSubscribe(Disposable p)	Provides the Observer with the means of cancelling (disposing) the connection (channel) with the Observable in both synchronous (from within Observer.onNext(Object)) and asynchronous manner.
(package private) void	remove(ObservableReplay.InnerDisposable<T> producer)	Atomically removes the given InnerDisposable from the observers array.
(package private) void	replay()	Tries to replay the buffer contents to all known observers.
(package private) void	replayFinal()	Tries to replay the buffer contents to all known observers.

 AtomicReference<ObservableReplay.ReplayObserver<T>> current)

Method Details

isDisposed

public boolean isDisposed()

Description copied from interface: Disposable

Returns true if this resource has been disposed.

Specified by:

isDisposed in interface Disposable

Returns:

true if this resource has been disposed

dispose

public void dispose()

Description copied from interface: Disposable

Dispose the resource, the operation should be idempotent.

Specified by:

dispose in interface Disposable

add

boolean add(ObservableReplay.InnerDisposable<T> producer)

Atomically try adding a new InnerDisposable to this Observer or return false if this Observer was terminated.

Parameters:

producer - the producer to add

Returns:

true if succeeded, false otherwise

remove

void remove(ObservableReplay.InnerDisposable<T> producer)

Atomically removes the given InnerDisposable from the observers array.

Parameters:

producer - the producer to remove

onSubscribe

public void onSubscribe(Disposable p)

Description copied from interface: Observer

Provides the Observer with the means of cancelling (disposing) the connection (channel) with the Observable in both synchronous (from within Observer.onNext(Object)) and asynchronous manner.

Specified by:

onSubscribe in interface Observer<T>

Parameters:

p - the Disposable instance whose Disposable.dispose() can be called anytime to cancel the connection

onNext

public void onNext(T t)

Description copied from interface: Observer

Provides the Observer with a new item to observe.

The Observable may call this method 0 or more times.

The Observable will not call this method again after it calls either Observer.onComplete() or Observer.onError(java.lang.Throwable).

Specified by:

onNext in interface Observer<T>

Parameters:

t - the item emitted by the Observable

onError

public void onError(Throwable e)

Description copied from interface: Observer

Notifies the Observer that the Observable has experienced an error condition.

If the Observable calls this method, it will not thereafter call Observer.onNext(T) or Observer.onComplete().

Specified by:

onError in interface Observer<T>

Parameters:

e - the exception encountered by the Observable

onComplete

public void onComplete()

Description copied from interface: Observer

Notifies the Observer that the Observable has finished sending push-based notifications.

The Observable will not call this method if it calls Observer.onError(java.lang.Throwable).

Specified by:

onComplete in interface Observer<T>

replay

void replay()

Tries to replay the buffer contents to all known observers.

replayFinal

void replayFinal()

Tries to replay the buffer contents to all known observers.
