Method Summary

Modifier and Type	Method	Description
final void	cancel()
protected void	completeDownstream()
protected boolean	errorDownstream(Throwable e)
final boolean	isCancelled()	Returns true if the downstream cancelled the sequence or the emitter was terminated via Emitter.onError(Throwable), Emitter.onComplete() or a successful FlowableEmitter.tryOnError(Throwable).
void	onComplete()	Signal a completion.
final void	onError(Throwable e)	Signal a Throwable exception.
(package private) void	onRequested()
(package private) void	onUnsubscribed()
final void	request(long n)
final long	requested()	The current outstanding request amount.
final FlowableEmitter<T>	serialize()	Ensures that calls to onNext, onError and onComplete are properly serialized.
final void	setCancellable(Cancellable c)	Sets a Cancellable on this emitter; any previous Disposable or Cancellable will be disposed/cancelled.
final void	setDisposable(Disposable d)	Sets a Disposable on this emitter; any previous Disposable or Cancellable will be disposed/cancelled.
boolean	signalError(Throwable e)
String	toString()
final boolean	tryOnError(Throwable e)	Attempts to emit the specified Throwable error if the downstream hasn't cancelled the sequence or is otherwise terminated, returning false if the emission is not allowed to happen due to lifecycle restrictions.

Constructor Details

BaseEmitter

BaseEmitter(org.reactivestreams.Subscriber<? super T> downstream)

Method Details

onComplete

public void onComplete()

Description copied from interface: Emitter

Signal a completion.

Specified by:

onComplete in interface Emitter<T>

completeDownstream

protected void completeDownstream()

onError

public final void onError(Throwable e)

Description copied from interface: Emitter

Signal a Throwable exception.

Specified by:

onError in interface Emitter<T>

Parameters:

e - the Throwable to signal, not null

tryOnError

public final boolean tryOnError(Throwable e)

Description copied from interface: FlowableEmitter

Attempts to emit the specified Throwable error if the downstream hasn't cancelled the sequence or is otherwise terminated, returning false if the emission is not allowed to happen due to lifecycle restrictions.

Unlike Emitter.onError(Throwable), the RxjavaPlugins.onError is not called if the error could not be delivered.

History: 2.1.1 - experimental

Specified by:

tryOnError in interface FlowableEmitter<T>

Parameters:

e - the throwable error to signal if possible

Returns:

true if successful, false if the downstream is not able to accept further events

signalError

public boolean signalError(Throwable e)

errorDownstream

protected boolean errorDownstream(Throwable e)

cancel

public final void cancel()

Specified by:

cancel in interface org.reactivestreams.Subscription

onUnsubscribed

void onUnsubscribed()

isCancelled

public final boolean isCancelled()

Description copied from interface: FlowableEmitter

Returns true if the downstream cancelled the sequence or the emitter was terminated via Emitter.onError(Throwable), Emitter.onComplete() or a successful FlowableEmitter.tryOnError(Throwable).

This method is thread-safe.

Specified by:

isCancelled in interface FlowableEmitter<T>

Returns:

true if the downstream cancelled the sequence or the emitter was terminated

request

public final void request(long n)

Specified by:

request in interface org.reactivestreams.Subscription

onRequested

void onRequested()

setDisposable

public final void setDisposable(Disposable d)

Description copied from interface: FlowableEmitter

Sets a Disposable on this emitter; any previous Disposable or Cancellable will be disposed/cancelled.

This method is thread-safe.

Specified by:

setDisposable in interface FlowableEmitter<T>

Parameters:

d - the disposable, null is allowed

setCancellable

public final void setCancellable(Cancellable c)

Description copied from interface: FlowableEmitter

Sets a Cancellable on this emitter; any previous Disposable or Cancellable will be disposed/cancelled.

This method is thread-safe.

Specified by:

setCancellable in interface FlowableEmitter<T>

Parameters:

c - the Cancellable resource, null is allowed

requested

public final long requested()

Description copied from interface: FlowableEmitter

The current outstanding request amount.

This method is thread-safe.

Specified by:

requested in interface FlowableEmitter<T>

Returns:

the current outstanding request amount

serialize

public final FlowableEmitter<T> serialize()

Description copied from interface: FlowableEmitter

Ensures that calls to onNext, onError and onComplete are properly serialized.

Specified by:

serialize in interface FlowableEmitter<T>

Returns:

the serialized FlowableEmitter

toString

public String toString()

Overrides:

toString in class AtomicLong
