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 MaybeEmitter.onSuccess(Object), MaybeEmitter.onError(Throwable), MaybeEmitter.onComplete() or a successful MaybeEmitter.tryOnError(Throwable).
void	onComplete()	Signal the completion.
void	onError(Throwable t)	Signal an exception.
void	onSuccess(T value)	Signal a success value.
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

onSuccess

public void onSuccess(T value)

Description copied from interface: MaybeEmitter

Signal a success value.

Specified by:

onSuccess in interface MaybeEmitter<T>

Parameters:

value - the value, not null

onError

public void onError(Throwable t)

Description copied from interface: MaybeEmitter

Signal an exception.

Specified by:

onError in interface MaybeEmitter<T>

Parameters:

t - the exception, not null

tryOnError

public boolean tryOnError(Throwable t)

Description copied from interface: MaybeEmitter

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 MaybeEmitter.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 MaybeEmitter<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: MaybeEmitter

Signal the completion.

Specified by:

onComplete in interface MaybeEmitter<T>

setDisposable

public void setDisposable(Disposable d)

Description copied from interface: MaybeEmitter

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 MaybeEmitter<T>

Parameters:

d - the disposable, null is allowed

setCancellable

public void setCancellable(Cancellable c)

Description copied from interface: MaybeEmitter

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 MaybeEmitter<T>

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: MaybeEmitter

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

This method is thread-safe.

Specified by:

isDisposed in interface Disposable

Specified by:

isDisposed in interface MaybeEmitter<T>

Returns:

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

toString

public String toString()

Overrides:

toString in class AtomicReference<Disposable>
