Method Summary

Modifier and Type	Method	Description
void	dispose()	Dispose the resource, the operation should be idempotent.
boolean	isDisposed()	Returns true if the downstream disposed the sequence or the emitter was terminated via CompletableEmitter.onError(Throwable), CompletableEmitter.onComplete() or a successful CompletableEmitter.tryOnError(Throwable).
void	onComplete()	Signal the completion.
void	onError(Throwable t)	Signal an exception.
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

onComplete

public void onComplete()

Description copied from interface: CompletableEmitter

Signal the completion.

Specified by:

onComplete in interface CompletableEmitter

onError

public void onError(Throwable t)

Description copied from interface: CompletableEmitter

Signal an exception.

Specified by:

onError in interface CompletableEmitter

Parameters:

t - the exception, not null

tryOnError

public boolean tryOnError(Throwable t)

Description copied from interface: CompletableEmitter

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 CompletableEmitter.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 CompletableEmitter

Parameters:

t - the throwable error to signal if possible

Returns:

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

setDisposable

public void setDisposable(Disposable d)

Description copied from interface: CompletableEmitter

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

Specified by:

setDisposable in interface CompletableEmitter

Parameters:

d - the disposable, null is allowed

setCancellable

public void setCancellable(Cancellable c)

Description copied from interface: CompletableEmitter

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

Specified by:

setCancellable in interface CompletableEmitter

Parameters:

c - the cancellable resource, null is allowed

dispose

public void dispose()

Description copied from interface: Disposable

Dispose the resource, the operation should be idempotent.

Specified by:

dispose in interface Disposable

isDisposed

public boolean isDisposed()

Description copied from interface: CompletableEmitter

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

This method is thread-safe.

Specified by:

isDisposed in interface CompletableEmitter

Specified by:

isDisposed in interface Disposable

Returns:

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

toString

public String toString()

Overrides:

toString in class AtomicReference<Disposable>
