void |
onSubscribe(Disposable d)
Provides the Observer with the means of cancelling (disposing) the
connection (channel) with the Observable in both
synchronous (from within
Observer.onNext(Object) ) and asynchronous manner. |

Observer
The Observable
may call this method 0 or more times.
The Observable
will not call this method again after it calls either Observer.onComplete()
or
Observer.onError(java.lang.Throwable)
.
public void onError(Throwable t)
Observer
Observable
has experienced an error condition.
If the Observable
calls this method, it will not thereafter call Observer.onNext(T)
or
Observer.onComplete()
.
public void onComplete()
Observer
Observable
has finished sending push-based notifications.
The Observable
will not call this method if it calls Observer.onError(java.lang.Throwable)
.
