AsyncSubject

java.lang.Object
- rx.Observable<R>
- - rx.subjects.Subject<T,T>
  - - rx.subjects.AsyncSubject<T>

Type Parameters:: T - the type of item expected to be observed by the Subject

All Implemented Interfaces:: Observer<T>

public final class AsyncSubject<T>
extends Subject<T,T>

Subject that publishes only the last item observed to each Observer that has subscribed, when the source Observable completes.

Example usage:

  // observer will receive no onNext events because the subject.onCompleted() isn't called. AsyncSubject<Object> subject = AsyncSubject.create(); subject.subscribe(observer); subject.onNext("one"); subject.onNext("two"); subject.onNext("three"); // observer will receive "three" as the only onNext event. AsyncSubject<Object> subject = AsyncSubject.create(); subject.subscribe(observer); subject.onNext("one"); subject.onNext("two"); subject.onNext("three"); subject.onCompleted();

```
- Method Detail
  - create
```
public static <T> AsyncSubject<T> create()
```
    Creates and returns a new AsyncSubject.
    
    Type Parameters:
    
    T - the result value type
    
    Returns:
    
    the new AsyncSubject
  - onCompleted
```
public void onCompleted()
```
    Description copied from interface: Observer
    
    Notifies the Observer that the Observable has finished sending push-based notifications.
    The Observable will not call this method if it calls Observer.onError(java.lang.Throwable).
  - onError
```
public void onError(Throwable e)
```
    Description copied from interface: Observer
    
    Notifies the Observer that the Observable has experienced an error condition.
    If the Observable calls this method, it will not thereafter call Observer.onNext(T) or Observer.onCompleted().
    
    Parameters:
    
    e - the exception encountered by the Observable
  - onNext
```
public void onNext(T v)
```
    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 either Observer.onCompleted() or Observer.onError(java.lang.Throwable).
    
    Parameters:
    
    v - the item emitted by the Observable
  - hasObservers
```
public boolean hasObservers()
```
    Description copied from class: Subject
    
    Indicates whether the Subject has Observers subscribed to it.
    
    Specified by:
    
    hasObservers in class Subject<T,T>
    
    Returns:
    
    true if there is at least one Observer subscribed to this Subject, false otherwise
