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 java.lang.Object implements MaybeObserver<T>
Wraps anotherMaybeObserver
and catches exceptions thrown by itsonSubscribe
,onSuccess
,onError
oronComplete
methods despite the protocol forbids it.Such exceptions are routed to the
RxJavaPlugins.onError(Throwable)
handler.- Since:
- 3.0.0

Called once the deferred computation completes normally.void
onError(@NonNull java.lang.Throwable e)
Notifies theMaybeObserver
that theMaybe
has experienced an error condition.void
onSubscribe(@NonNull Disposable d)
Provides theMaybeObserver
with the means of cancelling (disposing) the connection (channel) with theMaybe
in both synchronous (from withinonSubscribe(Disposable)

onSuccess(T t)
Notifies theMaybeObserver
with one item and that theMaybe

onSubscribe
public void onSubscribe(@NonNull @NonNull Disposable d)
Description copied from interface:MaybeObserver
Provides theMaybeObserver
with the means of cancelling (disposing) the connection (channel) with theMaybe
in both synchronous (from withinonSubscribe(Disposable)
itself) and asynchronous manner.- Specified by:
onSubscribe
in interfaceMaybeObserver<T>
- Parameters:
d
- theDisposable
instance whoseDisposable.dispose()
can be called anytime to cancel the connection
-
onSuccess
public void onSuccess(@NonNull T t)
Description copied from interface:MaybeObserver
Notifies theMaybeObserver
with one item and that theMaybe
has finished sending push-based notifications.The
Maybe
will not call this method if it callsMaybeObserver.onError(java.lang.Throwable)
.- Specified by:
onSuccess
in interfaceMaybeObserver<T>
- Parameters:
t
- the item emitted by theMaybe
-
onError
public void onError(@NonNull @NonNull java.lang.Throwable e)
Description copied from interface:MaybeObserver
Notifies theMaybeObserver
that theMaybe
has experienced an error condition.If the
Maybe
calls this method, it will not thereafter callMaybeObserver.onSuccess(T)
.- Specified by:
onError
in interfaceMaybeObserver<T>
- Parameters:
e
- the exception encountered by theMaybe
-
onComplete
public void onComplete()
Description copied from interface:MaybeObserver
Called once the deferred computation completes normally.- Specified by:
onComplete
in interfaceMaybeObserver<T>
