MaybeObserver
| io.reactivex.MaybeObserver<T> |
 Known Indirect Subclasses

Class Overview
Provides a mechanism for receiving push-based notifications.
After a MaybeObserver calls a Maybe's subscribe method,
first the Maybe calls onSubscribe(Disposable) with a Disposable that allows
cancelling the sequence at any time, then the
Maybe calls only one of the MaybeObserver's onSuccess(T), onError(Throwable) or
onComplete() methods to provide notifications.

Public Methods
public abstract void onComplete ()
Called once the deferred computation completes normally.
public abstract void onError (Throwable e)
Notifies the MaybeObserver that the Maybe has experienced an error condition.
If the Maybe calls this method, it will not thereafter call onSuccess(T).
Parameters
| e | the exception encountered by the Maybe |
|---|
public abstract void onSubscribe (Disposable d)
Provides the MaybeObserver with the means of cancelling (disposing) the
connection (channel) with the Maybe in both
synchronous (from within onSubscribe(Disposable) itself) and asynchronous manner.
Parameters
| d | the Disposable instance whose dispose() can
be called anytime to cancel the connection
|
|---|
public abstract void onSuccess (T t)
Notifies the MaybeObserver with one item and that the Maybe has finished sending
push-based notifications.
The Maybe will not call this method if it calls onError(Throwable).
Parameters
| t | the item emitted by the Maybe |
|---|
