Modifier and Type	Method	Description
static <T> Observer<T>	asObserver()
static <T> org.reactivestreams.Subscriber<T>	asSubscriber()
void	cancel()
void	dispose()	Dispose the resource, the operation should be idempotent.
boolean	isDisposed()	Returns true if this resource has been disposed.
void	onComplete()	Notifies the Observer that the Observable has finished sending push-based notifications.
void	onError(Throwable t)	Notifies the Observer that the Observable has experienced an error condition.
void	onNext(Object t)	Provides the Observer with a new item to observe.
void	onSubscribe(Disposable d)	Provides the Observer with the means of cancelling (disposing) the connection (channel) with the Observable in both synchronous (from within Observer.onNext(Object)) and asynchronous manner.
void	onSubscribe(org.reactivestreams.Subscription s)	Implementors of this method should make sure everything that needs to be visible in Subscriber.onNext(Object) is established before calling Subscription.request(long).
void	onSuccess(Object value)	Notifies the MaybeObserver with one item and that the Maybe has finished sending push-based notifications.
void	request(long n)
static EmptyComponent	valueOf(String name)	Returns the enum constant of this class with the specified name.
static EmptyComponent[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Method Details

values

public static EmptyComponent[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static EmptyComponent valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

asSubscriber

public static <T> org.reactivestreams.Subscriber<T> asSubscriber()

asObserver

public static <T> Observer<T> asObserver()

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: Disposable

Returns true if this resource has been disposed.

Specified by:

isDisposed in interface Disposable

Returns:

true if this resource has been disposed

request

public void request(long n)

Specified by:

request in interface org.reactivestreams.Subscription

cancel

public void cancel()

Specified by:

cancel in interface org.reactivestreams.Subscription

onSubscribe

public void onSubscribe(Disposable d)

Description copied from interface: Observer

Provides the Observer with the means of cancelling (disposing) the connection (channel) with the Observable in both synchronous (from within Observer.onNext(Object)) and asynchronous manner.

Specified by:

onSubscribe in interface CompletableObserver

Specified by:

onSubscribe in interface MaybeObserver<Object>

Specified by:

onSubscribe in interface Observer<Object>

Specified by:

onSubscribe in interface SingleObserver<Object>

Parameters:

d - the Disposable instance whose Disposable.dispose() can be called anytime to cancel the connection

onSubscribe

public void onSubscribe(org.reactivestreams.Subscription s)

Description copied from interface: FlowableSubscriber

Implementors of this method should make sure everything that needs to be visible in Subscriber.onNext(Object) is established before calling Subscription.request(long). In practice this means no initialization should happen after the request() call and additional behavior is thread safe in respect to onNext.

Specified by:

onSubscribe in interface FlowableSubscriber<Object>

Specified by:

onSubscribe in interface org.reactivestreams.Subscriber<Object>

onNext

public void onNext(Object t)

Description copied from interface: Observer

Provides the Observer with a new item to observe.

The Observable may call this method 0 or more times.

The Observable will not call this method again after it calls either Observer.onComplete() or Observer.onError(Throwable).

Specified by:

onNext in interface Observer<Object>

Specified by:

onNext in interface org.reactivestreams.Subscriber<Object>

Parameters:

t - the item emitted by the Observable

onError

public void onError(Throwable t)

Description copied from interface: Observer

Notifies the Observer that the Observable has experienced an error condition.

If the Observable calls this method, it will not thereafter call Observer.onNext(T) or Observer.onComplete().

Specified by:

onError in interface CompletableObserver

Specified by:

onError in interface MaybeObserver<Object>

Specified by:

onError in interface Observer<Object>

Specified by:

onError in interface SingleObserver<Object>

Specified by:

onError in interface org.reactivestreams.Subscriber<Object>

Parameters:

t - the exception encountered by the Observable

onComplete

public void onComplete()

Description copied from interface: Observer

Notifies the Observer that the Observable has finished sending push-based notifications.

The Observable will not call this method if it calls Observer.onError(Throwable).

Specified by:

onComplete in interface CompletableObserver

Specified by:

onComplete in interface MaybeObserver<Object>

Specified by:

onComplete in interface Observer<Object>

Specified by:

onComplete in interface org.reactivestreams.Subscriber<Object>

onSuccess

public void onSuccess(Object value)

Description copied from interface: MaybeObserver

Notifies the MaybeObserver with one item and that the Maybe has finished sending push-based notifications.

The Maybe will not call this method if it calls MaybeObserver.onError(Throwable).

Specified by:

onSuccess in interface MaybeObserver<Object>

Specified by:

onSuccess in interface SingleObserver<Object>

Parameters:

value - the item emitted by the Maybe
