Class SafeMaybeObserver<T>

java.lang.Object

io.reactivex.rxjava3.internal.observers.SafeMaybeObserver<T>

Type Parameters:

T - the element type of the sequence

All Implemented Interfaces:

MaybeObserver<T>

public final class SafeMaybeObserver<T>
extends Object
implements MaybeObserver<T>

Wraps another MaybeObserver and catches exceptions thrown by its onSubscribe, onSuccess, onError or onComplete methods despite the protocol forbids it.

Such exceptions are routed to the RxJavaPlugins.onError(Throwable) handler.

Since:

3.0.0

void	onSubscribe(@NonNull Disposable d)	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.

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 MaybeObserver<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(Throwable).

Specified by:

onSuccess in interface MaybeObserver<T>

Parameters:

t - the item emitted by the Maybe

onError

public void onError(@NonNull
 @NonNull Throwable e)

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 MaybeObserver<T>

Parameters:

e - 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 MaybeObserver<T>
