Method Details

onSubscribe

public void onSubscribe(@NonNull
 @NonNull Disposable d)

Description copied from interface: MaybeObserver

Provides the MaybeObserver with the means of cancelling (disposing) the connection (channel) with the Maybe in both synchronous (from within onSubscribe(Disposable) itself) and asynchronous manner.

Specified by:

onSubscribe in interface CompletableObserver

Specified by:

onSubscribe in interface MaybeObserver<T>

Specified by:

onSubscribe in interface SingleObserver<T>

Parameters:

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

onSuccess

public void onSuccess(@NonNull
 T t)

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(java.lang.Throwable).

Specified by:

onSuccess in interface MaybeObserver<T>

Specified by:

onSuccess in interface SingleObserver<T>

Parameters:

t - the item emitted by the Maybe

onError

public void onError(Throwable t)

Description copied from interface: MaybeObserver

Notifies the MaybeObserver that the Maybe has experienced an error condition.

If the Maybe calls this method, it will not thereafter call MaybeObserver.onSuccess(T).

Specified by:

onError in interface CompletableObserver

Specified by:

onError in interface MaybeObserver<T>

Specified by:

onError in interface SingleObserver<T>

Parameters:

t - the exception encountered by the Maybe

onComplete

public void onComplete()

Description copied from interface: MaybeObserver

Called once the deferred computation completes normally.

Specified by:

onComplete in interface CompletableObserver

Specified by:

onComplete in interface MaybeObserver<T>

cancelUpstream

void cancelUpstream()

clear

void clear()

cancel

public boolean cancel(boolean mayInterruptIfRunning)

Specified by:

cancel in interface Future<T>

Overrides:

cancel in class CompletableFuture<T>

complete

public boolean complete(T value)

Overrides:

complete in class CompletableFuture<T>

completeExceptionally

public boolean completeExceptionally(Throwable ex)

Overrides:

completeExceptionally in class CompletableFuture<T>
