Method Details
-
create
Constructs an empty UnicastSubject instance with the default capacity hint of 16 elements.- Type Parameters:
T
- the input and output value type- Returns:
- the created UnicastSubject instance
-
create
Constructs an empty UnicastSubject instance with a capacity hint.The capacity hint determines the internal queue's island size: the larger it is the less frequent allocation will happen if there is no subscriber or the subscriber hasn't caught up.
- Type Parameters:
T
- the input and output value type- Parameters:
capacityHint
- the capacity hint for the internal queue- Returns:
- the created BufferUntilSubscriber instance
-
create
Constructs an empty UnicastSubject instance with a capacity hint and an Action0 instance to call if the subject reaches its terminal state or the single Subscriber unsubscribes mid-sequence.The capacity hint determines the internal queue's island size: the larger it is the less frequent allocation will happen if there is no subscriber or the subscriber hasn't caught up.
- Type Parameters:
T
- the input and output value type- Parameters:
capacityHint
- the capacity hint for the internal queueonTerminated
- the optional callback to call when subject reaches its terminal state or the single Subscriber unsubscribes mid-sequence. It will be called at most once.- Returns:
- the created BufferUntilSubscriber instance
-
onNext
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 eitherObserver.onCompleted()
orObserver.onError(java.lang.Throwable)
.- Parameters:
t
- the item emitted by the Observable
-
onError
Description copied from interface:Observer
Notifies the Observer that theObservable
has experienced an error condition.If the
Observable
calls this method, it will not thereafter callObserver.onNext(T)
orObserver.onCompleted()
.- Parameters:
e
- the exception encountered by the Observable
-
onCompleted
public void onCompleted()Description copied from interface:Observer
Notifies the Observer that theObservable
has finished sending push-based notifications.The
Observable
will not call this method if it callsObserver.onError(java.lang.Throwable)
. -
hasObservers
public boolean hasObservers()Description copied from class:Subject
- Specified by:
hasObservers
in classSubject<T,
T> - Returns:
- true if there is at least one Observer subscribed to this Subject, false otherwise
