Package rx.subjects
Class PublishSubject<T>
java.lang.Object
rx.Observable<T>
rx.subjects.Subject<T,T>
rx.subjects.PublishSubject<T>
- Type Parameters:
T
- the type of items observed and emitted by the Subject
- All Implemented Interfaces:
Observer<T>
Subject that, once an
Observer
has subscribed, emits all subsequently observed items to the
subscriber.
Example usage:
PublishSubject<Object> subject = PublishSubject.create();
// observer1 will receive all onNext and onCompleted events
subject.subscribe(observer1);
subject.onNext("one");
subject.onNext("two");
// observer2 will only receive "three" and onCompleted
subject.subscribe(observer2);
subject.onNext("three");
subject.onCompleted();

Method Details
-
create
Creates and returns a newPublishSubject
.- Type Parameters:
T
- the value type- Returns:
- the new
PublishSubject
-
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)
. -
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
-
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:
v
- the item emitted by the Observable
-
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
-
hasThrowable
Check if the Subject has terminated with an exception.- Returns:
- true if the subject has received a throwable through
onError
.
-
hasCompleted
Check if the Subject has terminated normally.- Returns:
- true if the subject completed normally via
onCompleted
-
getThrowable
Returns the Throwable that terminated the Subject.- Returns:
- the Throwable that terminated the Subject or
null
if the subject hasn't terminated yet or it terminated normally.
