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 Emitter.onError(Throwable), Emitter.onComplete() or a successful ObservableEmitter.tryOnError(Throwable).
void	onComplete()	Signal a completion.
void	onError(Throwable t)	Signal a Throwable exception.
void	onNext(T t)	Signal a normal value.
ObservableEmitter<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: ObservableEmitter

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 ObservableEmitter<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>

setDisposable

public void setDisposable(Disposable d)

Description copied from interface: ObservableEmitter

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 ObservableEmitter<T>

Parameters:

d - the Disposable, null is allowed

setCancellable

public void setCancellable(Cancellable c)

Description copied from interface: ObservableEmitter

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 ObservableEmitter<T>

Parameters:

c - the Cancellable resource, null is allowed

serialize

public ObservableEmitter<T> serialize()

Description copied from interface: ObservableEmitter

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

Specified by:

serialize in interface ObservableEmitter<T>

Returns:

the serialized ObservableEmitter

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: ObservableEmitter

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

This method is thread-safe.

Specified by:

isDisposed in interface Disposable

Specified by:

isDisposed in interface ObservableEmitter<T>

Returns:

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

toString

public String toString()

Overrides:

toString in class AtomicReference<Disposable>
