Method Detail
-
subscribeActual
protected void subscribeActual(Observer<? super T> observer)
Description copied from class:Observable
Operator implementations (both source and intermediate) should implement this method that performs the necessary business logic and handles the incomingObserver
s.There is no need to call any of the plugin hooks on the current
Observable
instance or theObserver
; all hooks and basic safeguards have been applied byObservable.subscribe(Observer)
before this method gets called.- Specified by:
subscribeActual
in classObservable<T>
- Parameters:
observer
- the incomingObserver
, nevernull
-
onSubscribe
public void onSubscribe(Disposable d)
Description copied from interface:Observer
Provides theObserver
with the means of cancelling (disposing) the connection (channel) with theObservable
in both synchronous (from withinObserver.onNext(Object)
) and asynchronous manner.- Specified by:
onSubscribe
in interfaceObserver<T>
- Parameters:
d
- theDisposable
instance whoseDisposable.dispose()
can be called anytime to cancel the connection
-
onNext
public void onNext(T t)
Description copied from interface:Observer
Provides theObserver
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 eitherObserver.onComplete()
orObserver.onError(java.lang.Throwable)
.
-
onError
public void onError(java.lang.Throwable t)
Description copied from interface:Observer
Notifies theObserver
that theObservable
has experienced an error condition.If the
Observable
calls this method, it will not thereafter callObserver.onNext(T)
orObserver.onComplete()
.
-
onComplete
public void onComplete()
Description copied from interface:Observer
Notifies theObserver
that theObservable
has finished sending push-based notifications.The
Observable
will not call this method if it callsObserver.onError(java.lang.Throwable)
.- Specified by:
onComplete
in interfaceObserver<T>
-
emitLoop
void emitLoop()
Loops until all notifications in the queue has been processed.
-
test
public boolean test(java.lang.Object o)
Description copied from interface:Predicate
Test the given input value and return a boolean.
-
hasObservers
public boolean hasObservers()
Description copied from class:Subject
Returns true if the subject has any Observers.The method is thread-safe.
- Specified by:
hasObservers
in classSubject<T>
- Returns:
- true if the subject has any Observers
-
hasThrowable
public boolean hasThrowable()
Description copied from class:Subject
Returns true if the subject has reached a terminal state through an error event.The method is thread-safe.
- Specified by:
hasThrowable
in classSubject<T>
- Returns:
- true if the subject has reached a terminal state through an error event
- See Also:
Subject.getThrowable()
,Subject.hasComplete()
-
getThrowable
@Nullable public @Nullable java.lang.Throwable getThrowable()
Description copied from class:Subject
Returns the error that caused the Subject to terminate or null if the Subject hasn't terminated yet.The method is thread-safe.
- Specified by:
getThrowable
in classSubject<T>
- Returns:
- the error that caused the Subject to terminate or null if the Subject hasn't terminated yet
-
hasComplete
public boolean hasComplete()
Description copied from class:Subject
Returns true if the subject has reached a terminal state through a complete event.The method is thread-safe.
- Specified by:
hasComplete
in classSubject<T>
- Returns:
- true if the subject has reached a terminal state through a complete event
- See Also:
Subject.hasThrowable()
