Method Summary

Modifier and Type	Method	Description
(package private) void	drain()
(package private) void	drainLoop()
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.
void	onError(Throwable t)	Signal a Throwable exception.
void	onNext(T t)	Signal a normal value.
long	requested()	The current outstanding request amount.
FlowableEmitter<T>	serialize()	Ensures that calls to onNext, onError and onComplete are properly serialized.
void	setCancellable(Cancellable c)	Sets a Cancellable on this emitter; any previous Disposable or Cancellable will be disposed/cancelled.
void	setDisposable(Disposable d)	Sets a Disposable on this emitter; any previous Disposable or Cancellable will be disposed/cancelled.
String	toString()
boolean	tryOnError(Throwable t)	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.

Method Details

onNext

public void onNext(T t)

Description copied from interface: Emitter

Signal a normal value.

Specified by:

onNext in interface Emitter<T>

Parameters:

t - the value to signal, not null

onError

public void onError(Throwable t)

Description copied from interface: Emitter

Signal a Throwable exception.

Specified by:

onError in interface Emitter<T>

Parameters:

t - the Throwable to signal, not null

tryOnError

public boolean tryOnError(Throwable t)

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:

t - the throwable error to signal if possible

Returns:

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

onComplete

public void onComplete()

Description copied from interface: Emitter

Signal a completion.

Specified by:

onComplete in interface Emitter<T>

drain

void drain()

drainLoop

void drainLoop()

setDisposable

public 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 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 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

isCancelled

public 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

serialize

public 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 AtomicInteger
